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 23 November 2023[update] there are 5,046 codes defined in ISO 3166-2. For some countries, codes are defined for more than one level of subdivisions.
Current codes
[edit]The following table can be used to access the current ISO 3166-2 codes of each country, and comprises three columns:[2]
- Entry: ISO 3166-1 alpha-2 code, click to view the ISO 3166-2 codes of the country
- Country name: English short name officially used by the ISO 3166 Maintenance Agency (ISO 3166/MA)
- Subdivisions assigned codes: Number and category of subdivisions assigned codes in ISO 3166-2;[1] if there are more than one level of subdivisions, the first-level subdivisions are shown in italics
Subdivisions included in ISO 3166-1
[edit]For the following countries,[note 2] a number of their subdivisions in ISO 3166-2, most of them dependent territories, are also officially assigned their own country codes in ISO 3166-1:[2]
| Entry | Country name | Subdivisions included in ISO 3166-1 (alpha-2 code) |
|---|---|---|
| CN | China | CN-TW Taiwan (TW) [note 1] CN-HK Hong Kong (HK) CN-MO Macao (MO) |
| FI | Finland | FI-01 ?land (AX) |

Notes
[edit]- ^ a b 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".
- ^ a b Not including dependent territories of Australia, Denmark, New Zealand, or the United Kingdom of Great Britain and Northern Ireland, nor Bouvet Island of Norway.
- ^ a b c Collectively Bonaire, Sint Eustatius and Saba are officially assigned their own country codes in ISO 3166-1.
- ^ a b Collectively Svalbard and Jan Mayen are officially assigned their own country codes in ISO 3166-1.
Format
[edit]The format of the ISO 3166-2 codes is different for each country. The codes may be alphabetic, numeric, or alphanumeric, and they may also be of constant or variable length. The following is a table of the ISO 3166-2 codes of each country (those with codes defined), grouped by their format: [citation needed]

Changes
[edit]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.
