Vietnam Country Code (+84) and Common Vietnam Codes (VN, VNM, VND, .vn)

The Vietnam country code is one of the most common details people need when they are traveling, studying abroad, working remotely, or contacting a Vietnamese business. At the same time, the phrase Vietnam country code can also mean different identifiers used in forms, shipping tools, websites, and payments. This guide starts with the phone dialing code for Vietnam (+84) and shows you how to format landline and mobile calls correctly. It then explains other widely used Vietnam codes such as VN, VNM, 704, .vn, VND, and more, so you can choose the right code for the right task.

What Is the Vietnam Country Code?

When most people search for “country code Vietnam” or “what is the country code for Vietnam,” they usually mean the telephone country calling code used to route international calls. However, you may also see “Vietnam country code” used in a broader sense for ISO country codes, the internet domain, and other standardized identifiers. Understanding which “code system” a website or document is asking for helps you avoid form errors, failed phone calls, and shipping delays.

In the sections below, you will first learn the practical dialing rules for Vietnam phone numbers. After that, you will find the most common Vietnam codes used in databases, travel bookings, payments, online accounts, and logistics. If something does not work, it is often a formatting issue (for example, keeping a domestic leading zero) or using the wrong code type in the wrong field.

The official telephone country calling code for Vietnam is +84

The official telephone country calling code for Vietnam is +84 in international format. You will see it in phone number pickers, country calling code dropdowns, and contact forms because it tells the phone network (or an app) that the destination is Vietnam. In practical terms, +84 is the prefix that makes a call “international to Vietnam,” before the rest of the Vietnamese number is dialed.

Country Codes, Phone Codes, Dialing Codes, Telephone Codes, ISO Country Codes

It is common to see the code written as “+84” or “84.” The plus sign is important because it is a placeholder for the international access or exit code, which is different depending on the country you are calling from. For example, a mobile phone usually accepts “+” directly, while some office phones require you to dial an exit code first and then “84.” If a call fails even though the number looks correct, it may be due to numbering plan updates, a missing digit, or a local system that does not accept “+,” so it is reasonable to verify the current format with the recipient.

What people mean by “country code” beyond phone calls

The phrase “Vietnam country code” can also refer to several other standardized identifiers that are not related to phone dialing. For example, ISO country codes identify Vietnam in databases and forms (VN, VNM, and 704). The internet uses a country domain (.vn). Finance systems use a currency code (VND). You may also encounter time zone references (UTC+7), barcode prefixes (893), and postal codes for deliveries.

This article focuses first on how to call Vietnam using the Vietnam country calling code +84, because it is the most time-sensitive and error-prone task for travelers and international callers. After that, it covers other common Vietnam codes that appear in online forms, travel bookings, shipping portals, and business tools. Each code type is an identifier within its own system, and it should be used only for the purpose the field describes, not as proof of origin, manufacturing location, or legal status.

• Phone calling code: +84
• ISO country codes: VN, VNM, 704 (and subdivision patterns like VN-XX)
• Internet domain: .vn (and common categories like com.vn)
• Currency: VND
• Time zone: UTC+7
• Barcode prefix allocation: 893 (GS1)
• Postal codes: numeric local codes used for shipping and address validation

Quick checklist: which Vietnam code you need for your task

Choosing the right Vietnam code depends on what you are trying to do. If you are calling a person or a hotel in Vietnam, you need the Vietnam dialing code +84 and a correctly formatted phone number. If you are filling a country dropdown on a website, you typically need “Vietnam” or the ISO two-letter code “VN.” If you are setting prices, paying an invoice, or checking exchange rates, you want the currency code “VND.” For websites and digital targeting, you may look for .vn domains, but that is separate from phone and ISO codes.

Calling Code From Different Countries

Practical scenarios make this easier. A traveler activating a SIM may need to enter a phone number in +84 format for app verification. A student filling a university form may need VN in a “Country code (2 letters)” field. A remote worker shipping a laptop to Vietnam needs a complete address and a postal code, plus a reachable +84 phone number for the courier. If you are not sure which code is required, read the field label and hint text carefully, because many forms separate “Country” from “Calling code” and may add the calling code automatically.

If you are not sure, do not guess. Look for a tooltip, placeholder text, or an example next to the field, and check whether the system expects a phone calling code, an ISO country code, or a postal code.

How to Call Vietnam Using the +84 Country Code

Calling Vietnam from another country is straightforward once you understand the international dialing structure. The most common problem is not the Vietnam country code itself, but how the rest of the number is written in domestic format inside Vietnam. Many Vietnamese numbers are shown with a leading 0 for domestic calls, and that digit usually must be removed when dialing internationally.

This section gives you a stable, repeatable method that works for both landlines and mobile numbers: use +84 and then dial the rest of the national number without the domestic trunk prefix. You will also see practical examples using placeholders, so you can convert a number you receive by email, messaging, or a website into the correct international format.

International dialing format: exit code + 84 + destination number

The general international dialing structure is: international exit code (from the country you are calling from) + Vietnam country code 84 + the destination number in Vietnam. The destination number may start with a geographic area code (for landlines) or a mobile prefix (for mobile phones). Since exit codes vary by country and phone system, many people avoid the exit code entirely by using the “+84” format on smartphones and modern calling apps.

Calling International Numbers | How to Dial Abroad

A safe pattern to remember is: +84 [area or mobile prefix] [local number]. The brackets represent digits you receive from the person or business you are calling. The exact spacing and punctuation are not important; the digits are what matter. If you are calling from a system that does not accept the “+” symbol, you may need to replace “+” with the international access code used by your carrier or your office PBX.

1. Get the full Vietnamese number as it is written locally (often starts with 0).
2. Remove the domestic leading 0 if it is present.
3. Add +84 at the beginning.
4. Dial using your phone app, or paste the number into your calling or messaging app.
5. If “+” does not work, use your local exit code, then dial 84, then the rest of the number.

If you still cannot connect, confirm that you have the complete number (including area code for landlines) and that international calling is enabled on your line or plan.

Calling Vietnam landlines: removing the domestic leading zero

Many countries use a domestic trunk prefix, often written as a leading 0, to route calls within the country. Vietnam phone numbers are frequently written in a domestic format that starts with 0, especially for landlines. When you call Vietnam from outside the country, you typically do not dial that domestic 0. Instead, you use the Vietnam country calling code +84 and then dial the rest of the digits.

How To Call Vietnam From America (USA)

A simple rule works in most cases: if the Vietnamese number is written as 0X ... for domestic dialing, drop the 0 and replace it with +84 for international dialing. For example, a landline displayed as 0AA BBBB CCCC becomes +84 AA BBBB CCCC. Do not worry about spaces or hyphens, because different websites format numbers differently; focus on keeping the same digits in the same order.

Landline calls often fail when the caller leaves the 0 in place after +84, or when the landline number is provided without enough digits. If a business listing seems incomplete, ask for the number “in international format” to confirm it is ready for callers abroad.

Calling Vietnam mobile numbers from outside Vietnam

Vietnam mobile numbers use mobile network prefixes rather than geographic area codes, but the international approach is the same: start with +84 and then dial the national number without the domestic leading 0. Locally, a mobile number is often written starting with 0. Internationally, that 0 is usually removed because +84 already tells the network you are calling Vietnam.

How do I dial a Vietnam number?

Here are example transformations using placeholder digits (not real personal numbers). These show the conversion process rather than a specific carrier or city. If you receive a number that looks unusually short, or a prefix that seems outdated, confirm with the recipient, because numbers can be ported between networks and numbering rules can be updated over time.

• Domestic: 0M AAAA BBBB → International: +84 M AAAA BBBB
• Domestic: 0M AAA BBB CCC → International: +84 M AAA BBB CCC
• Domestic: 0M AABB CCDD → International: +84 M AABB CCDD

For travelers, two practical checks reduce frustration. First, confirm whether you are roaming or using local service, because roaming restrictions or plan limits can block international calls. Second, if you are using WhatsApp, Telegram, or another VoIP app, make sure the contact is saved with +84 format so the app matches the number correctly across networks and SIM changes.

Saving Vietnam contacts correctly on smartphones and messaging apps

The most reliable way to save Vietnam phone numbers is to use an E.164-style format: +84 followed by the full national number without the domestic trunk prefix (the leading 0). This format is widely recognized by smartphone dialers and messaging apps, and it reduces confusion when you travel or switch SIM cards. It also helps caller ID systems and contact matching features recognize the same person consistently.

If you are moving to Vietnam or working with Vietnamese contacts long-term, it is worth cleaning up old entries that were saved in mixed formats. A contact saved with a domestic 0 might work locally but fail abroad, or it may create duplicate conversations in messaging apps. Also consider dual-SIM phones: you may need to select the correct outbound line (local SIM vs home SIM) when placing an international call or when registering a number for verification.

• Remove a leading 0 after you add +84 (do not keep both).
• Do not omit digits because of spaces or hyphens; copy the full number.
• Avoid saving two versions of the same contact (one with 0, one with +84).
• Check you are not mixing landline formatting with a mobile number, or vice versa.
• When dialing, confirm the correct SIM line is selected for international calls.

A quick cleanup method is to search your contacts for numbers that start with “0” and update any Vietnam entries to start with +84 instead. After updating, open your main messaging apps and let them re-sync to reduce duplicate threads.

Vietnam Phone Number Formats and Area Codes

Vietnam phone numbers can look different depending on whether they are landlines or mobile numbers, and whether they are shown for domestic use or international callers. Some listings include spaces, hyphens, or parentheses, which can make the number seem more complex than it really is. The key is to recognize which part is the national trunk prefix (often 0) and which part identifies the landline area or the mobile network prefix.

This section helps you interpret the structure of a number you receive and explains why incomplete numbers cause many call failures. It also provides a few well-known city area code examples as recognition aids, without trying to act as a full directory.

Landline vs mobile numbers: what the structure tells you

In general, Vietnam landline numbers include a geographic area code, which links the number to a city or province. Mobile numbers use mobile prefixes that are not tied to a single city in the same way, especially when people move and keep their numbers. When you see a number written with a city name (for example, an office contact), it is often a landline and may require the area code to be dialed correctly.

How to Make an International Phone Call?

Published formats often include punctuation such as spaces, hyphens, or parentheses to make numbers easier to read. These characters do not change what you dial internationally. If you are unsure whether a number is landline or mobile, ask the sender to provide it in full international format starting with +84. That request also helps you detect incomplete numbers, such as a landline missing its area code or a shortened internal extension that only works within a company phone system.

If you receive a number that seems too short, it may be an internal extension. In that case, ask for the company’s main line in +84 format and the extension separately.

Common major city area code examples to recognize

Some Vietnam area codes are widely referenced because they are attached to major business centers and travel hubs. For recognition purposes only, many people associate Hanoi with area code 24 and Ho Chi Minh City with area code 28. You may see these codes embedded in business cards, hotel listings, and office contact pages, often written in a domestic form that starts with 0 and then the area code.

Flights to America and Japan | Vietnam Travel Guide

Examples like these are not a complete directory, and area codes and numbering plans can change over time. If a call does not connect, confirm the number on the organization’s official contact page, recent email signature, or a trusted booking confirmation. A practical method is to cross-check the number against the address shown on the website, because legitimate businesses usually publish consistent location and contact details in one place.

Examples only: the purpose of these samples is to help you recognize common patterns, not to provide an exhaustive list of Vietnam area codes.

If you need an up-to-date reference for a specific location, check an official telecom operator help page or a current numbering plan reference provided by a recognized telecommunications authority.

Why calls fail: the most frequent formatting errors

Most failed calls to Vietnam are caused by formatting mistakes rather than network outages. The most frequent issue is keeping the domestic leading 0 after adding +84, which creates an invalid number in many systems. Another common issue is missing an area code for landlines, especially when a number is copied from a local advertisement or spoken over the phone. Entering too few digits can also happen when punctuation is mistaken for part of the number, or when a caller copies only the “local” portion without the prefix.

Vietnam Dialing Code - Vietnamese Country Code - Telephone Area Codes in Vietnam

Phone systems also differ. A mobile phone dialer usually accepts “+84” directly, while a hotel phone, office PBX, or calling card service may require a specific exit sequence before the country code. This is why the same number may work on one device and fail on another. Time-of-day and network congestion can also affect connection quality, but it is best to rule out formatting first because it is the most controllable factor.

1. Confirm you have the complete number (landline area code or mobile prefix included).
2. If the number starts with 0 domestically, remove the 0 for international dialing.
3. Try dialing with +84 on a smartphone or app.
4. If “+” is not accepted, dial your local exit code, then 84, then the rest of the number.
5. If it still fails, confirm the digits from a current official source and try again.

If the format is correct but the call fails intermittently, consider network conditions, roaming restrictions, or whether international calling is enabled on your plan.

Vietnam ISO Country Codes (VN, VNM, and 704)

ISO country codes are standardized identifiers used in many systems that need consistent country data, such as shipping platforms, airline bookings, analytics dashboards, and enterprise databases. These are different from the Vietnam telephone country code +84 and are usually used when a system needs to store or validate country information in a compact format. You may be asked for a two-letter code, a three-letter code, or a numeric code depending on the tool.

Understanding the difference saves time when a form rejects your input. For example, a field labeled “Country code (2 letters)” expects VN, not +84. A data export may use VNM or 704 instead of writing “Vietnam.” The following subsections explain where each version appears and how to choose correctly.

ISO alpha-2 code: VN

Vietnam’s ISO alpha-2 country code is VN. This two-letter code is widely used in online forms, country dropdowns, shipping tools, and account settings because it is compact and easy for systems to validate. You may also see it in address validation workflows and location-based settings where a platform stores a standardized country value behind the scenes.

It is important not to confuse VN with the Vietnam phone code +84. VN identifies the country as a record in a database, while +84 routes a phone call. Some systems are strict and will only accept two letters, so typing “Vietnam” or “VNM” can cause validation errors. When you see hints like “2-character code” or “ISO 3166-1 alpha-2,” VN is the expected input.

If a form rejects VN, check whether it expects “Vietnam” as a full name instead of a code, or whether you selected a different country in another linked field.

ISO alpha-3 code: VNM

Vietnam’s ISO alpha-3 code is VNM. Three-letter codes are often preferred in reporting, logistics, and datasets because they can be more readable than numeric codes while staying standardized. You may encounter VNM in trade documentation, internal dashboards, spreadsheets, or data feeds where countries are represented with consistent three-character identifiers.

When you work across multiple systems, the same country might be stored as “Vietnam,” “VN,” or “VNM.” Matching these consistently is a common data task. In spreadsheets or exports, one practical approach is to filter or search for “VNM” when you suspect the dataset uses alpha-3 codes, then map it to your required format. Always confirm the field definition, because not all three-letter country abbreviations follow ISO rules in every product.

• When you will see this: trade or shipping datasets, analytics dashboards, some government or NGO reporting templates
• Helpful tip: if you cannot find “Vietnam” in a list, try searching for VNM in the same column

ISO numeric code: 704

Vietnam’s ISO numeric country code is 704. Numeric codes are used in some standardized data exchanges and in older systems where numbers reduce issues with language, character sets, or localization. You might see 704 in customs-related datasets, legacy databases, or reporting formats that use numeric identifiers for countries.

Because “704” is just a number, it can also appear in other contexts that have nothing to do with country identification (for example, internal codes, product IDs, or unrelated numeric fields). For that reason, confirm that the field is explicitly labeled as an ISO numeric country code or a country numeric identifier. If you are integrating data between systems, store both the human-readable value (Vietnam) and the code to make troubleshooting easier later.

ISO subdivision codes for Vietnam regions (ISO 3166-2)

ISO subdivision codes identify regions within a country using a standardized pattern. For Vietnam, these codes typically start with the country prefix VN followed by a separator and additional characters that represent a province or municipality. You may see patterns like VN-XX, where the suffix varies by region and is defined by the ISO 3166-2 standard.

Subdivision codes are useful in compliance tools, address normalization systems, and region-level reporting where a consistent “province code” is needed across languages. Instead of listing every subdivision code (which can change and is better handled from a maintained reference list), focus on recognizing the pattern and storing it correctly. For data teams, a practical approach is to store both the human-readable region name and the subdivision code when it is available, so users can interpret reports even if they do not know the coding scheme.

If your form or dataset requests an ISO 3166-2 code, check whether it expects a specific string format like VN-XX rather than a province name typed in free text.

Vietnam Internet and Digital Location Codes

Digital platforms use a different set of “codes” to represent Vietnam online. These include the Vietnam country domain (.vn), common second-level domain patterns used by organizations, and configuration values in apps such as phone calling codes, country selectors, currency display, and time zone settings. These identifiers can help you recognize Vietnam-linked web presence and configure accounts correctly, but they should not be treated as automatic proof of legitimacy or physical location.

This section explains what .vn typically signals, how common domain patterns are used, and how to avoid the most frequent mismatches in online forms. These tips are especially useful when you are setting up accounts from abroad, arranging local deliveries, or managing payments and profiles tied to Vietnam.

Vietnam country domain: .vn

Vietnam’s country-code top-level domain is .vn. A website using .vn often indicates a Vietnam-focused online presence, such as a local business, a service targeting customers in Vietnam, or a Vietnam-oriented version of a brand. The .vn domain space is administered through Vietnam’s domain management framework, and you may see references to Vietnam’s domain authority in registrar and policy contexts.

It is important to understand what .vn does and does not mean. A .vn domain suggests a connection to Vietnam in naming and registration, but it does not automatically prove that a website is official, safe, or physically located in Vietnam. Travelers should still verify sensitive pages carefully, such as payment pages, visa-related services, airline booking portals, and government information pages, even if the domain looks local. Use trusted bookmarks, check for consistent contact details, and confirm you are on the correct site before entering personal or payment information.

If you are choosing a domain for a business, .vn can signal local relevance and may be helpful for audiences in Vietnam, but requirements and processes can vary, so confirm the current rules with an official registrar.

Common second-level domains under .vn and what they usually indicate

Under .vn, you may encounter common second-level domain patterns that resemble category labels, such as commercial, education, or government-oriented naming. Examples people often recognize include com.vn, edu.vn, and gov.vn. These patterns are conventions that can help you understand the likely purpose of a site at a glance, especially when comparing multiple search results or evaluating a link shared in a message.

At the same time, naming conventions are not universal proof of legitimacy. Some categories can have eligibility rules, and the details can change, so businesses should verify current registration requirements with an official registrar or the relevant authority. When setting up a website, many organizations choose between a brand domain (for example, a short brand name under .vn) and a category domain (such as a commercial category), depending on audience expectations and registration options.

If you are unsure, treat the domain as one signal among many and verify the organization through official contact pages and trusted channels.

Using Vietnam codes in digital forms and platforms

Many platforms ask for Vietnam-related codes during account setup and checkout. Common examples include a country selector (Vietnam or VN), a phone field (+84), currency displays (VND), and time zone configuration (UTC+7). Problems often occur when these fields are inconsistent, such as selecting Vietnam in the country dropdown but entering a phone number that is not in Vietnam format, or entering “VN” where the form expects a postal code.

A practical approach is to treat each field as a separate system with its own expected format. Some forms split phone input into two parts: a country dropdown that sets the calling code automatically, and a local number field. If a form rejects “+84,” look for a separate country or calling code selector that will add 84 for you. For international readers setting up accounts, it also helps to keep one “reference” version of your address and phone number in a notes app so you can paste consistent values.

• Country: choose Vietnam (or VN if the system asks for two letters)
• Phone: use +84 and remove the domestic leading 0
• Address: include district and city/province clearly
• Currency: confirm whether amounts are shown in VND or another currency
• Time zone: set UTC+7 when scheduling Vietnam-based times

If you see repeated validation errors, re-check the field label and whether the platform is asking for a “calling code,” an “ISO country code,” or a “postal code,” because these values are not interchangeable.

Vietnam Currency, Time Zone, and Trade Identifiers

Beyond phone and country identifiers, you will frequently encounter Vietnam codes related to money, time, and trade. These codes are used in payment systems, invoices, booking platforms, product labeling, and international logistics. Knowing the basics helps you confirm you are paying in the correct currency, scheduling meetings at the correct local time, and interpreting product and standards references without confusion.

This section covers the most common practical identifiers: the Vietnam currency code VND, Vietnam’s UTC+7 time zone, the GS1 barcode prefix allocation 893, and the TCVN standards identifier format. Each item serves a specific purpose in a specific system, so the key is to use it only where it applies and to confirm details from official documentation for compliance-critical decisions.

Currency code for Vietnam: VND

The currency code for Vietnam is VND, which refers to the Vietnamese dong. You will see VND in exchange rate apps, invoices, bank transfer references, payroll tools, and travel budgeting platforms. It is common to see currency codes alongside country selection, which is why people sometimes mix them up, but VND is not a country code and it is not a phone code.

When booking hotels, flights, or tours, always confirm the currency shown on the payment screen, not only on the search results page. Some platforms display prices in a “display currency” while charging in a different “settlement currency” depending on your card, location, or account settings. Remote workers and freelancers should also separate invoice currency (what you bill in) from settlement currency (what you receive after conversion), because bank fees and exchange rates can change the final amount.

• Common displays: VND, ₫, or “đ” (formatting depends on the platform)
• Practical check: confirm currency on the final checkout or invoice summary page
• For invoicing: specify currency code (VND) in writing to avoid misunderstandings

If you see a large number of zeros, that can be normal for VND amounts, so rely on the currency label rather than the number size alone.

Vietnam time zone: UTC+7

Vietnam uses the time zone UTC+7. This matters for international calls, online meetings, flight and train schedules, customer support hours, and deadline-driven work with Vietnamese teams. When you coordinate across regions, stating “UTC+7” reduces ambiguity, because city names and device time zone labels can vary by language and platform.

A simple conversion method is to start from UTC and add seven hours to get Vietnam time. For example, 12:00 UTC corresponds to 19:00 in Vietnam (UTC+7). For meeting invites, include both the city label (for example, Vietnam time) and the UTC offset, and consider adding a calendar link that automatically converts time for attendees in different regions.

• Meeting invite checklist: include UTC+7, include a city label, and confirm the date
• Team coordination tip: repeat the time in both your local time and UTC+7 in messages
• Deadline tip: specify the time zone in writing, not only the clock time

If someone misses a meeting, confirm whether the issue was a time zone conversion problem or a connectivity issue before changing schedules.

Vietnam GS1 barcode prefix: 893

The GS1 barcode prefix 893 is associated with barcode number allocations connected to Vietnam, and it appears at the beginning of many product barcodes that are registered through the relevant GS1 member organization. Retail and supply-chain systems sometimes use this prefix as a quick indicator of where the barcode number was issued, which can help with cataloging and basic inventory workflows.

It is important to understand the limitation: a barcode prefix indicates where the barcode number is issued, not necessarily where a product was manufactured. A company can register barcodes in one country and manufacture in another, or use different supply chains for different markets. For compliance, import/export, or origin claims, businesses should rely on official documentation and applicable labeling rules rather than assuming origin from a barcode alone.

• Myth: 893 always means “Made in Vietnam.”
• Fact: 893 is linked to barcode issuance allocation, not guaranteed manufacturing origin.
• Myth: barcode prefix is enough for customs decisions.
• Fact: customs and compliance decisions require proper paperwork and verified origin information.

For compliance-critical decisions, consult current GS1 documentation and your supply-chain partners’ records.

Vietnam standards identifiers: TCVN

You may encounter TCVN in product specifications, procurement documents, and compliance discussions related to Vietnam. TCVN is commonly used as an identifier for Vietnam national standards, usually shown as an acronym followed by a standard number and often a year. Seeing a reference like TCVN ####:YYYY generally means the document is pointing to a defined technical standard with a specific scope and version.

For importers, exporters, and procurement teams, the most important practical step is to confirm which standard version applies. Standards can be updated, and a supplier may reference an older or newer edition depending on contract terms. If a TCVN reference appears in documentation, request the full standard title, the version year, and the applicability statement (what the standard covers) before making design, labeling, or testing decisions.

Example format (placeholders only): TCVN ####:YYYY. Always seek official documentation or authoritative guidance when a standard is required for regulatory or safety reasons.

Vietnam Postal Codes and Addressing for Deliveries

Postal codes and address formatting become important when you ship items to Vietnam, order online deliveries, or complete address verification in international platforms. Unlike phone codes and ISO country codes, a Vietnam postal code is part of an address system used by postal and courier services to route mail. It is usually numeric, but its exact length and how strictly it is enforced can vary by carrier and by the form you are using.

This section focuses on practical delivery success: how to use postal codes when required, how to write an internationally readable Vietnam address, and how to avoid mixing up postal codes with VN, +84, or other identifiers. If you ship frequently or at high value, consider validating addresses using a trusted carrier tool or confirming the details directly with the recipient.

Vietnam postal codes: what they look like and when to use them

Vietnam uses postal codes for mail routing and address validation, and they are commonly presented as numeric codes. Depending on the platform, you may see postal codes handled with different lengths or formatting rules, especially across international e-commerce systems. The safest approach is to treat the postal code as a precise value provided for the specific area and not to guess it.

Postal codes matter most for international shipping labels, courier deliveries, online shopping checkouts, and automated address verification tools. If the recipient does not know the postal code, ask them to confirm it or check an official source rather than entering a random number just to pass validation. Some forms require a postal code even if a local recipient rarely uses it in daily life, so it may be necessary to obtain the correct code for the destination district or ward/commune.

• If a form requires a postal code: ask the recipient or check an official lookup source
• If a form accepts blanks: leave the field empty rather than guessing
• If delivery is urgent: include an accurate +84 phone number so the courier can call

Address completeness often matters more than punctuation. Ensure that street, district, and city/province fields are clear and consistent with the recipient’s location.

• Address checklist: recipient name, phone (+84), street and building, ward/commune, district, city/province, postal code (if available)

How to write a Vietnam address for international mail and couriers

International forms often expect addresses in a top-down structure (street, city, country), while local conventions may list smaller administrative units differently. For reliable international delivery, write the address in a clear, line-by-line format that includes all key subdivisions such as ward/commune and district, plus the city/province. This helps couriers route packages correctly even if they do not recognize abbreviations.

Include a reachable Vietnam phone number in international format +84 because couriers commonly call recipients to confirm location, schedule delivery, or resolve access issues. If possible, keep Vietnamese diacritics in the address because they improve local readability. If a system cannot accept special characters, provide a plain-ASCII version that preserves the same words and order.

Sample template (placeholders only):

[Recipient Name]

[Street Address, Building, Apartment]

[Ward/Commune], [District]

[City/Province] [Postal Code]

VIETNAM

Phone: +84 [national number without leading 0]

If a form provides separate fields for ward/commune and district, fill them carefully instead of combining everything into one street line.

Avoiding mix-ups between postal codes, ISO codes, and phone codes

Mix-ups happen because many checkout pages ask for multiple “codes” close together. A common error is entering “VN” into a postal code field, or pasting a postal code into a country code box that expects VN or VNM. Another frequent issue is entering “84” in a phone number field that expects the entire number with “+84,” or leaving the domestic leading 0 in place after selecting Vietnam as the calling country.

The most reliable fix is to match the field label to the correct system: “Country” is a country name or ISO code; “Phone” is the dialing format starting with +84; “Postal code” is the local numeric routing code; and “State/Province” is the region name (or a region code if explicitly requested). For businesses shipping at volume, validating addresses with a trusted carrier tool reduces returned parcels and customer support time.

If a checkout fails, re-check whether the system has a separate “calling code” dropdown and whether it auto-fills part of the phone number field.

Other Vietnam Codes You Might Encounter in Travel and Sports

In travel and international event contexts, Vietnam may be represented by codes that are not ISO country codes and are not phone codes. Sports bodies, event organizers, and ticketing systems sometimes use their own abbreviations to fit scoreboards, schedules, and roster formats. These codes are useful for reading listings quickly, but they should not be used in official administrative forms unless the form explicitly requests them.

This section explains the common sports code VIE and provides a simple way to remember which Vietnam code applies to which real-world task. If you are moving between travel bookings, business forms, and messaging apps, this mapping helps you avoid using the right code in the wrong place.

Vietnam sports country code: VIE

Vietnam is often represented as VIE in major international sports contexts, including common Olympic-style listings and some football or tournament schedules. These organization codes are designed for compact display on scoreboards and fixtures, and they may differ from ISO standards used in business and government datasets.

It is important to distinguish VIE from ISO and phone identifiers. VIE is not the ISO alpha-3 code (Vietnam’s ISO alpha-3 is VNM), and it is not the Vietnam country calling code (+84). In practical terms, use VIE only when an event system or sports listing uses it, such as when reading match schedules, checking group tables, or scanning a roster.

• VIE: sports and organization listings
• VNM: ISO alpha-3 for datasets and reporting
• VN: ISO alpha-2 for forms and country fields
• +84: telephone country calling code for Vietnam

For travelers, do not use VIE in official administrative forms unless the form explicitly asks for a sports or organization code.

A simple way to remember which Vietnam code to use

A practical way to remember Vietnam codes is to tie each code to a task. Calling someone in Vietnam uses +84. Selecting the country in a dropdown uses VN. Working in international datasets may use VNM or 704. Vietnam websites often use .vn. Prices and payments use VND. Sports listings often use VIE. When you connect each code to a scenario, it becomes harder to confuse them.

For example: save a hotel contact as +84 so WhatsApp can find it; choose Vietnam (VN) in booking forms; check that the payment screen shows VND; and treat a barcode prefix like 893 as an issuance allocation signal, not a manufacturing guarantee. If you still feel uncertain, confirm what the field label is asking for before you submit.

With these mappings in mind, the remaining common questions are usually about formatting phone numbers correctly and choosing the right field value when a form is strict.

Frequently Asked Questions

What is the Vietnam country code for phone calls?

The Vietnam telephone country calling code is +84. Use +84 at the start of the number when calling Vietnam from abroad. If your phone system does not accept the plus sign, dial your local international exit code first and then 84.

Do I keep the leading 0 when dialing a Vietnam number internationally?

No, you usually remove the domestic leading 0 when dialing internationally. Replace the leading 0 with +84 and then dial the remaining digits. This rule applies to many landline and mobile formats shown for domestic use.

Why does a website reject +84 in the phone field?

It rejects +84 when the form expects you to select the country separately and enter only the local number. Look for a country dropdown or a calling code selector that automatically adds 84. If there is no selector, try entering the number with +84 and no spaces, or follow the exact example shown in the field hint.

Is VN the same as the Vietnam country code?

No, VN is an ISO country code used in databases and forms, not a phone dialing code. The phone code is +84, while VN is the two-letter identifier for Vietnam in ISO standards. Use VN only when a field explicitly asks for a two-letter country code.

What currency code is used for Vietnam in payments and invoices?

Vietnam’s currency code is VND for the Vietnamese dong. You will see VND on invoices, exchange services, and checkout screens. Confirm the currency on the final payment page to avoid paying in an unintended display currency.

Does a barcode starting with 893 mean the product is made in Vietnam?

No, 893 indicates the barcode number allocation is associated with Vietnam, not guaranteed manufacturing origin. The barcode prefix helps identify where the number was issued, but supply chains can span multiple countries. For origin claims, rely on labeling and official documentation rather than barcode prefix alone.

What time zone should I use when scheduling with Vietnam?

Use UTC+7 for Vietnam time. Including UTC+7 in meeting invites reduces confusion for people in other regions. When possible, add the UTC offset and a calendar invitation so conversions happen automatically.

Vietnam uses several different “codes,” and each one belongs to a specific system. For phone calls, +84 is the key, and most dialing issues come from keeping the domestic leading 0 or missing digits. For forms and data, VN, VNM, and 704 appear in different contexts, while VND, UTC+7, .vn, postal codes, and 893 show up in payments, scheduling, websites, shipping, and product workflows. If something fails, re-check the field label, confirm the expected format, and ask for the value in the system’s standard form (such as a phone number written in +84 format).
