ISO 3166-2
|
|
ISO 3166-2 is the second part of the ISO 3166 standard. It is a geocode system created for coding the names of subdivisions of countries (subnational entities) and dependent areas. The purpose of the standard is to establish a worldwide series of short abbreviations for places, for use on package labels, containers, and such; anywhere where a short alphanumeric code can serve to clearly indicate a location in a more convenient and less ambiguous form than the full place name. There are around 3700 different codes.

Format
ISO 3166-2 codes consist of two parts, separated by a hyphen. The first part is the ISO 3166-1 alpha-2 code element, the second is alphabetic or numeric and has one, two or three digits. The second part often is based on national standards.

Decoding / Encoding lists
To find the ISO 3166-2 codes for each country see ISO 3166-1, a list of countries. If you are familiar with the two-letter country codes (similar to internet country codes) you can also use the format matrix given below.
Both ways would lead to articles like ISO 3166-2:XX, where XX stands for the ISO 3166-1 code, e.g. ISO 3166-2:AU leads to the code list for Australia.
