ISO 3166-1 is part of the ISO 3166 standard published by the International Organization for Standardization (ISO), and defines codes for the names of countries, dependent territories, and special areas of geographical interest. The official name of the standard is Codes for the representation of names of countries and their subdivisions – Part 1: Country codes. It defines three sets of country codes:^[1]

• ISO 3166-1 alpha-2 — two-letter country codes which are the most widely used of the three, and used most prominently for the Internet's country code top-level domains (with a few exceptions).
• ISO 3166-1 alpha-3 — three-letter country codes which allow a better visual association between the codes and the country names than the alpha-2 codes.
• ISO 3166-1 numeric — three-digit country codes which are identical to those developed and maintained by the United Nations Statistics Division, with the advantage of script (writing system) independence, and hence useful for people or systems using non-Latin scripts.

ISO 3166 has included alphabetic country codes since its first edition in 1974, and numeric country codes since its second edition in 1981. The country codes were first published as ISO 3166-1 in 1997 in the fifth edition of ISO 3166, when ISO 3166 were divided into three separate parts.^[2]

As a widely used international standard, ISO 3166-1 is implemented in other standards and used by international organizations,^[3] to allow facilitation of the exchange of goods and information.^[4] However, it is not the only standard for country codes. Other country codes used by many international organizations are partly or totally incompatible with ISO 3166-1,^[5] although some of them closely correspond to ISO 3166-1 codes.

[edit] Criteria for inclusion

Currently 246 countries, territories, or areas of geographical interest are assigned official codes in ISO 3166-1. According to the ISO 3166 Maintenance Agency (ISO 3166/MA), the only way to enter a new country name into ISO 3166-1 is to have it registered in one of the following two sources:^[6]

• United Nations Terminology Bulletin Country Names, or
• Country and Region Codes for Statistical Use of the UN Statistics Division.

To be listed in the bulletin Country Names, a country must either be:

• A member country of the United Nations,
• A member of one of its specialized agencies, or
• A party to the Statute of the International Court of Justice.

The list of names in Country and Region Codes for Statistical Use of the UN Statistics Division is based on the bulletin Country Names and other UN sources.

Once a country name or territory name appears in either of these two sources, it will be added to ISO 3166-1 by default.

[edit] Information included

ISO 3166-1 is published officially in both English and French. Since the second edition of ISO 3166-1, the following columns are included for each entry:

1. COUNTRY NAME English (or French) short name
2. English (or French) short name lower case
3. English (or French) full name
4. Alpha-2 code
5. Alpha-3 code
6. Numeric code
7. Remarks
8. Independent (# denotes the country is considered a sovereign state)
9. Additional information: Administrative language(s) alpha-2
10. Additional information: Administrative language(s) alpha-3
11. Additional information: Local short name(s)

[edit] Current codes

[edit] Officially assigned code elements

The following is a complete ISO 3166-1 encoding list of the countries which are assigned official codes. It is listed in alphabetical order by the English short country names officially used by the ISO 3166/MA, which are all from United Nations sources.^[7] For example, Macedonia is listed as "Macedonia, the former Yugoslav Republic of" because of the Macedonia naming dispute, and Taiwan is listed as "Taiwan, Province of China" because of its political status within the UN (the Republic of China is not recognized by the UN).

[edit] Reserved and user-assigned code elements

Besides the officially assigned codes, code elements may be expanded by using either reserved codes or user-assigned codes.^[9]

Reserved code elements are codes which have become obsolete, or are required in order to enable a particular user application of the standard but do not qualify for inclusion in ISO 3166-1. To avoid transitional application problems and to aid users who require specific additional code elements for the functioning of their coding systems, the ISO 3166/MA, when justified, reserves these codes which it undertakes not to use for other than specified purposes during a limited or indeterminate period of time. Codes are usually reserved for former countries, overseas territories, international organizations, and special nationality status. The reserved alpha-2 and alpha-3 codes can be divided into the following four categories (click on the links for the reserved codes of each category):

• Alpha-2: exceptional reservations, transitional reservations, indeterminate reservations, and codes currently agreed not to use
• Alpha-3: exceptional reservations, transitional reservations, indeterminate reservations, and codes currently agreed not to use
• Numeric: no reserved codes

User-assigned code elements are codes at the disposal of users who need to add further names of countries, territories, or other geographical entities to their in-house application of ISO 3166-1, and the ISO 3166/MA will never use these codes in the updating process of the standard. The following codes can be user-assigned:

• Alpha-2: AA, QM to QZ, XA to XZ, and ZZ
• Alpha-3: AAA to AAZ, QMA to QZZ, XAA to XZZ, and ZZA to ZZZ
• Numeric: 900 to 999

[edit] Editions and changes

There have been two editions of ISO 3166-1. The first edition (ISO 3166-1:1997) was published on 1997-09-25, and the second edition (ISO 3166-1:2006) was published on 2006-11-20 (later corrected by its Technical Corrigendum 1, ISO 3166-1:2006/Cor 1:2007, published on 2007-07-15).

Between different editions, the ISO 3166/MA updates the code lists by announcing the changes in newsletters.^[10] A country is usually assigned new ISO 3166-1 codes if it changes its name or its territorial boundaries. In general, new alphabetic codes are assigned if a country changes a significant part of its name, while a new numeric code is assigned if a country changes its territorial boundaries. Codes for formerly used country names that were deleted from ISO 3166-1 are published in ISO 3166-3.
