ISO 3166-1 alpha-2 Totally Explained

Everything about Iso 3166-1 Alpha-2 totally explained

ISO 3166-1 alpha-2 codes are two-letter country codes in the ISO 3166-1 standard to represent countries and dependent territories. They are published by the International Organization for Standardization (ISO) as part of its ISO 3166 standard. They are the most widely used of the country codes published by ISO, and are used most prominently for country code top-level domains (with a few changes). They were first included as part of the ISO 3166 standard in its first edition in 1974.

Uses and applications

The codes are used in different environments and are also part of other standards. In some cases they're not perfectly implemented.

Perfect implementations

The two-letter ISO 3166-1 codes are used in:

ISO 3901 — International Standard Recording Code
ISO 4217 — Currency codes
ISO 6166 — International Securities Identifying Number (ISIN) system
ISO 7372 — Trade data interchange (Trade data elements directory)
ISO 9362 — SWIFT codes (Bank Identifier Codes)
ISO 9375
ISO 13616 — International Bank Account Numbers
UN/LOCODE — United Nations Code for Trade and Transport Locations, implemented by the United Nations Economic Commission for Europe
IETF language tags

Imperfect implementations

Starting in 1985, two-letter codes have been used in the domain name system as country code top-level domains (ccTLDs). Currently, the Internet Assigned Numbers Authority assign the ccTLDs, mostly following the ISO 3166-1 alpha-2 codes, but with a few exceptions (for example, the United Kingdom requested an exceptional reservation of .uk for their ccTLD instead of their native .gb).
The WIPO coding standard ST.3 uses alpha-2 codes for encoding states, other entities and intergovernmental organizations (and their Patent/Trademark Offices), but includes a number of additional codes. For these additional codes, see the section Codes currently agreed not to use. NATO country codes are also based on ISO 3166-1 alpha-2.
The European Commission uses ISO 3166-1 alpha-2 with two exceptions: EL (not GR) is used for Greece, and UK (not GB) is used for the United Kingdom.

Changes to ISO 3166-1 alpha-2 are tracked by ISO 3166-3.
