ISO 3166-2
From Wikipedia, the free encyclopedia
ISO 3166-2 is part of the ISO 3166 standard published by the International Organization for Standardization (ISO), and defines codes for the names of 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 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:
- 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. Currently there are more than 4200 codes defined in ISO 3166-2.[1]
For some countries, codes are defined for more than one level of subdivisions.[2] The codes for the first-level subdivisions are defined in the official standard without the ISO 3166-1 alpha-2 code of the country as prefix (to distinguish from the codes for the second-level subdivisions), and thus do not guarantee uniqueness in a global context by themselves. These codes can be completed by adding the alpha-2 code as prefix.

[edit] Current codes
The following is a complete table of the current officially assigned ISO 3166-2 codes by each country, with three columns:
- Alpha-2 — ISO 3166-1 alpha-2 code of the country (click on alpha-2 code for ISO 3166-2 codes of the country)
- Country name — English short country name officially used by the ISO 3166 Maintenance Agency (ISO 3166/MA)
- Subdivisions assigned codes — Subdivisions currently assigned codes in ISO 3166-2 (first-level subdivisions in italics); since ISO 3166-2 is only occasionally updated, they do not necessarily reflect the latest subdivision changes
[edit] Subdivisions included in ISO 3166-1
For the following countries, a number of their subdivisions in ISO 3166-2, most of them dependent territories, are also assigned their own country codes in ISO 3166-1:
| Alpha-2 | Country name | Subdivisions included in ISO 3166-1 (alpha-2) |
|---|---|---|
| CN | China | CN-91 Hong Kong (HK) CN-92 Macao (MO) CN-71 Taiwan (TW)[note 1] |
| FI | Finland | FI-AL Åland (AX) |
| FR | France | FR-GF French Guiana (GF) FR-PF French Polynesia (PF) FR-TF French Southern Territories (TF) FR-GP Guadeloupe (GP) FR-MQ Martinique (MQ) FR-YT Mayotte (YT) FR-NC New Caledonia (NC) FR-RE Réunion (RE) FR-BL Saint Barthélemy (BL) FR-MF Saint Martin (MF) FR-PM Saint Pierre and Miquelon (PM) FR-WF Wallis and Futuna (WF) |
| NO | Norway | NO-22 Jan Mayen (SJ)[note 2] NO-21 Svalbard (SJ)[note 2] |
| US | United States | US-AS American Samoa (AS) US-GU Guam (GU) US-MP Northern Mariana Islands (MP) US-PR Puerto Rico (PR) US-UM United States Minor Outlying Islands (UM) US-VI Virgin Islands, U.S. (VI) |
- Notes
- ^ Taiwan is included as a subdivision of China, as the United Nations considers it as part of China even though it is not de facto under the jurisdiction of the People's Republic of China. In ISO 3166-1, Taiwan is listed as "Taiwan, Province of China" due to its political status within the UN.
- ^ a b Collectively Svalbard and Jan Mayen is assigned its own country codes in ISO 3166-1.
[edit] Format
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 grouped by their format (excluding countries with no defined codes):
| Number of characters (second part) | Alphabetic | Numeric | Alphanumeric |
|---|---|---|---|
| constant 1 character |
AR, BO, EC, FJ, GM, KI, KM, LS, LU, MG, SL, ST, TG, TM, VE | AT, GA, IS, NE, PA | |
| constant 2 characters |
AE, AM, AL, BI, BJ, BN, BR, BS, BW, BY, CA, CD, CH, CL, CM, CV, DE, DJ, ER, ET, FI, GE, GH, GQ, GT, GW, GY, HN, HT, HU, ID, IN, IQ, IT, JO, KW, LA, LB, LR, LT, LY, MD, MU, MW, NA, NG, NI, NL, NP, OM, PK, PL, QA, SB, SH, SK, SN, SO, SR, SV, SY, SZ, TJ, TL, US, UY, UZ, WS, YE, ZA, ZW | AD, AG, BA, BB, BD, BG, BH, CI, CN, CU, CY, DK, DM, DO, DZ, EE, GD, HR, IR, JM, JP, KN, KR, LC, LI, LK, ME, MK, MM, MT, MY, NO, NR, PT, RS, RW, SA, SC, SD, SG, SM, TN, TO, TR, TZ, UA, UM, VC, VN, ZM | BT, FR, GR |
| constant 3 characters |
AF, AO, BE, BF, FM, GB, KP, KZ, MA, MH, MX, NZ, PE, PG, PH, TT, TV, TW, VU | KE, PW, SI, UG | CZ |
| variable 1 or 2 characters |
CR, ES, GN, IE, IL, KG, RO, SE | KH | TH |
| variable 1 or 3 characters |
MZ | MN | ML |
| variable 2 or 3 characters |
AU, AZ, BZ, CF, CO, LV, RU, TD | MR, MV | |
| variable 1, 2, or 3 characters |
EG | CG, PY |
Note: For countries where codes are defined for more than one level of subdivisions, the format shown here is of the codes for the second-level subdivisions, i.e., the codes defined in the official standard with the ISO 3166-1 alpha-2 code of the country as prefix.
[edit] Editions and changes
There have been two editions of ISO 3166-2. The first edition (ISO 3166-2:1998) was published on 1998-12-20, and the second edition (ISO 3166-2:2007) was published on 2007-12-13.
Between different editions, the ISO 3166/MA updates the code lists by announcing the changes in newsletters.[3] Changes in ISO 3166-2 comprise mostly of spelling corrections, addition and deletion of subdivisions, and modification of the administrative structure.
