Overview#

ISO 3166-1 alpha-2 is the 2 letter Country Code.

ISO 3166-1 alpha-2 is published by the International Organization for Standardization (ISO), to represent countries, dependent territories, and special areas of geographical interest.

ISO 3166-1 alpha-2 are the most widely used of the country codes published by ISO (the others being ISO 3166-1 alpha-3 and numeric), and are used most prominently for the Internet's country code top-level domains (with a few exceptions).

ISO 3166-1 alpha-2 were first included as part of the standard in its first edition of ISO 3166.

ISO 3166-1 alpha-2 codes are used in different environments and are also part of other standards. In some cases they are not perfectly implemented.

ISO 3166-1 alpha-2 are used within other codes or applications, for example,

• ISO 4217 Currency Code
• ISO 3901 International Standard Recording Code (ISRC)
• ISO 6166 International Securities Identifying Number (ISIN)
• ISO 9362 Bank Identifier Codes (BIC or SWIFT code)
• ISO 13616 International Bank Account Number (IBAN)
• ISO 15511 International Standard Identifier for Libraries and Related Organizations (ISIL)
• UN/LOCODE United Nations Code for Trade and Transport Locations and United Nations Economic Commission for Europe
• with deviations, for Country Code Top-Level Domain (ccTLDs) on the Internet: list of Internet TLDs.
  • United Kingdom, whose ISO 3166-1 alpha-2 code is GB, uses .UK instead of .gb as its ccTLD, as UK is currently exceptionally reserved in ISO 3166-1 alpha-2 on the request of the United Kingdom.
