ISO 3166-1 alpha-2

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

Perfect implementations

Imperfect implementations

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.

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.^[2] This notwithstanding, Commission Regulation (EC) No 2645/98 of 9 December 1998 on the nomenclature of countries and territories for the external trade statistics of the Community and statistics of trade between Member States specified GB for the United Kingdom and GR for Greece.^[3]

The United Nations uses a combination of ISO 3166 two- and three- letter codes, along with codes that pre-date ISO 3166, for international vehicle registration codes, the codes on the oval stickers used to identify foreign road vehicles.

Officially assigned code elements

Below is a complete list of the current officially assigned ISO 3166-1 alpha-2 codes, with three columns:

User-assigned code elements

The following alpha-2 codes can be user-assigned: AA, from QM to QZ, from XA to XZ, and ZZ. These code elements are 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 them in the updating process of the standard. For example:

Reserved code elements

Reserved code elements are codes which, while not ISO 3166-1 codes, are in use for some applications in conjunction with the ISO 3166 codes. The ISO 3166/MA therefore reserves them, so that they are not used for new official
