ISO 3166-2

ISO 3166-2 is part of the ISO 3166 standard published by the International Organization for Standardization (ISO), and defines codes for identifying the principal subdivisions (e.g., provinces or states) of all countries coded in ISO 3166-1. The official name of the standard is Codes for the representation of names of countries and their subdivisions Part 2: Country subdivision code. It was first published in 1998.

The purpose of ISO 3166-2 is to establish an international standard of short and unique alphanumeric codes to represent the relevant administrative divisions and dependent territories of all countries in a more convenient and less ambiguous form than their full names. Each complete ISO 3166-2 code consists of two parts, separated by a hyphen:[1]

  • The first part is the ISO 3166-1 alpha-2 code of the country;
  • The second part is a string of up to three alphanumeric characters, which is usually obtained from national sources and stems from coding systems already in use in the country concerned, but may also be developed by the ISO itself.

Each complete ISO 3166-2 code can then be used to uniquely identify a country subdivision in a global context.

As of 22 November 2019 there are 4,964 codes defined in ISO 3166-2. For some countries, codes are defined for more than one level of subdivisions.

Current codes

  1. In ISO 3166-1, three countries are listed as subdivisions of the Netherlands. However, the mentioned Netherlands is a country on its own with the three other countries being its dependent territories. The four countries together constitute the Kingdom of the Netherlands.
  2. Taiwan is included as a subdivision of China because of its political status within the United Nations, as, even though it is de facto under the jurisdiction of the Republic of China instead of the People's Republic of China, the United Nations does not recognize the Republic of China and considers Taiwan as part of China. In ISO 3166-1, Taiwan is listed as "Taiwan, Province of China".
  3. Collectively Bonaire, Sint Eustatius and Saba are officially assigned their own country codes in ISO 3166-1.
  4. Collectively Svalbard and Jan Mayen are officially assigned their own country codes in ISO 3166-1.

The ISO 3166/MA updates ISO 3166-2 when necessary. Changes in ISO 3166-2 consist mostly of spelling corrections, addition and deletion of subdivisions, and modification of the administrative structure.

ISO used to announce changes in newsletters which updated the currently valid standard, and releasing new editions which comprise a consolidation of newsletter changes. As of July 2013, changes are published in the online catalogue of ISO only and no newsletters are published anymore. Past newsletters remain available on the ISO website.
