Mongolia ISO Codes: MN, MNG, 496, and .mn

Mongolia ISO codes identify the country in different data and communication systems, but they are not all interchangeable. The official ISO 3166-1 set is MN for alpha-2, MNG for alpha-3, and 496 for the numeric code. You may also see .mn for websites, +976 for international calls, MNT for currency, and MGL in Olympic data. This guide explains what each Mongolia country code means and which value to use for a specific task.

Mongolia ISO Codes at a Glance

The phrase "Mongolia country code" can refer to several standards. The three values below are the official ISO 3166-1 identifiers, while the other codes in this article belong to internet, telephone, currency, or sports systems.

The Three ISO 3166-1 Codes for Mongolia

The official ISO Online Browsing Platform record lists Mongolia with alpha-2 code MN, alpha-3 code MNG, and numeric code 496. It also identifies Mongolia as independent and the assignment status as officially assigned. These are the values to use when a system specifically requests ISO 3166-1 data.

How Mongolia's ISO Codes Are Used

The MN Alpha-2 Country Code

MN is Mongolia's two-letter country code under ISO 3166-1. It is the correct value when a form, database, or application requests an ISO alpha-2 country code. Field labels may include ISO alpha-2, ISO 3166-1 alpha-2, or country code, two letters.

For example, a customer-address record might store MN in its country-code field, while a shipping or registration form may use the same value to identify Mongolia. Alpha-2 codes are compact, so they are common in country selectors, regional datasets, and software configuration. However, MN is not a universal replacement for every Mongolia-related abbreviation. A telephone, currency, domain, or sports field may require a different standard.

The letters MN also appear in the .mn internet domain. This shared assignment explains the connection between the two values, but a DNS domain ending and an ISO country field serve different purposes.

The MNG Alpha-3 and 496 Numeric Codes

MNG is Mongolia's three-letter ISO 3166-1 code. It is useful when a system requests a more readable three-letter country abbreviation, such as an ISO alpha-3 or ISO 3166-1 alpha-3 value. Do not substitute MGL, the Olympic abbreviation, when an ISO alpha-3 code is required.

496 is Mongolia's ISO 3166-1 numeric code. It is a three-digit identifier designed for systems that use numbers instead of letters, including some statistical, administrative, or data-exchange records. The number should be treated as an ISO country value, not as a general abbreviation.

In particular, 496 is not Mongolia's international telephone code. It identifies Mongolia in ISO 3166-1 numeric data; the international calling code is +976. The receiving system's specification determines whether the correct entry is MNG or 496, because the alpha-3 and numeric formats are separate fields rather than interchangeable versions of the same abbreviation.

Mongolia's Internet Domain, Calling Code, and Currency Code

Mongolia also has identifiers used for websites, telephone networks, and money. Their values may look similar to ISO country codes, but each belongs to a different technical standard.

The .mn Country-Code Top-Level Domain

.mn is Mongolia's country-code top-level domain, or ccTLD. It is used at the end of internet domain names and can appear in website addresses or email addresses. The letters match Mongolia's ISO alpha-2 code, MN, which makes the domain easy to associate with the country.

How to register a domain name in Mongolia (.mn)

The domain is not an alternative form of the ISO country code. DNS delegation is managed through the internet domain-name system. The IANA .mn Domain Delegation Data provides the delegation information for this ccTLD and identifies its designated manager. ISO assigns country-code identifiers; IANA and the relevant domain manager handle the DNS role.

Use .mn when the task concerns a domain name or website address. Do not enter it in a database field labeled ISO alpha-2 country code, and do not assume that a .mn domain alone proves the owner's residence, nationality, or legal jurisdiction.

The +976 International Calling Code

+976 is the international telephone calling code for Mongolia. It belongs to the international numbering system and is used when addressing a Mongolian telephone number from another country. The plus sign is important because it signals an international calling prefix rather than a general country identifier.

The Telephone numbers in Mongolia reference identifies 976 as Mongolia's telephone country code. This value is separate from all three ISO 3166-1 codes. If an application asks for a telephone country calling code, use +976; if it asks for the ISO numeric country code, use 496. One must not be entered in place of the other when dialing, formatting, or validating a phone number.

The MNT Currency Code

MNT is the ISO 4217 alphabetic currency code for Mongolia's tögrög. It belongs to the currency-code standard, not to ISO 3166-1. Use it in price displays, invoices, payment records, exchange-rate data, and other fields that explicitly request a currency code.

The ISO 4217 — Currency codes page explains that currency alphabetic codes are based partly on ISO 3166 country codes. That is why MNT begins with MN and can resemble a Mongolia country abbreviation. The resemblance does not make MNT another country code.

Some currency listings also associate MNT with the numeric value 496, which can create an additional data-entry trap because 496 is Mongolia's ISO 3166-1 numeric country code as well. The standards remain distinct: MNT identifies the currency, while 496 identifies the country when the field is defined as ISO 3166-1 numeric. A price record may therefore need both a country field and a currency field, with each value stored separately.

Other Abbreviations That Can Mean Mongolia

The MGL Olympic Code and the Historical MON Code

MGL is the Olympic or IOC code used for Mongolia. It is a sports abbreviation, not Mongolia's ISO alpha-3 code. A sports results system or Olympic dataset that requests the IOC code should use MGL, while an ISO-based country field should use MNG for alpha-3 data.

A reference table of List of IOC country codes also records MON as a historical code associated with Mongolia at the 1968 Winter Games. MON should be treated as historical, not as a current replacement for MGL or MNG. Historical datasets may preserve it to describe past events, but current Olympic or ISO mappings should follow the code system named by the data provider.

How to Choose the Correct Mongolia Code

Match the Code to the Field or Task

The words country code are incomplete unless the standard or format is specified. Use this decision list to match the value to its primary function:

• ISO 3166-1 alpha-2: use MN for a two-letter Mongolia country code.
• ISO 3166-1 alpha-3: use MNG for a three-letter Mongolia country code.
• ISO 3166-1 numeric: use 496 for the three-digit country identifier.
• Website or DNS domain: use .mn for Mongolia's country-code top-level domain.
• International telephone call: use +976 as Mongolia's calling code.
• Currency: use MNT for the Mongolian tögrög.
• Olympic or IOC sports data: use MGL for the current sports abbreviation.

A single record can legitimately contain several of these values. For example, an international customer profile may use MN for the ISO alpha-2 country field, +976 for a phone field, and MNT for a currency field. Before entering or exporting a Mongolia-related code, check which standard and code format the receiving field requires. Follow the field definition or technical documentation rather than selecting a value based only on the phrase "country code."

A Quick Verification Checklist

When accuracy matters, use a short standards-based check:

1. For an ISO country identifier, consult the current Mongolia record in the ISO Online Browsing Platform and confirm whether the field requires alpha-2, alpha-3, or numeric format.
2. For a website or domain question, check IANA's current .mn delegation information rather than treating a general country-code list as DNS documentation.
3. For telephone, currency, or sports data, consult the relevant numbering, currency, or sports authority and confirm that the value is current for that system.
4. Compare the requested standard, spelling, and code length before importing, validating, or exporting the record.

This approach is especially useful when a value appears in more than one standard. MN and MNT share a prefix, and 496 can appear in both country and currency contexts, so the field label and standard name provide the necessary meaning.

Conclusion: Mongolia Code Quick Reference

Mongolia's official ISO 3166-1 codes are MN for alpha-2, MNG for alpha-3, and 496 for numeric data. The related identifiers are .mn for internet domains, +976 for international calls, MNT for the currency, and MGL for Olympic data. Keep each value tied to its governing system, and the correct Mongolia code becomes straightforward to select.
