ISO 3166-2:GW

From Wikipedia, the free encyclopedia

ISO 3166-2:GW is the entry for Guinea-Bissau in ISO 3166-2, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), which defines codes for the names of the principal subdivisions (e.g., provinces or states) of all countries coded in ISO 3166-1.

Currently for Guinea-Bissau, ISO 3166-2 codes are defined for two levels of subdivisions:

The autonomous sector Bissau is the capital of the country and has special status equal to the regions.

Each code consists of two parts, separated by a hyphen. The first part is GW, the ISO 3166-1 alpha-2 code of Guinea-Bissau. The second part is either of the following:

  • one letter: provinces
  • two letters: autonomous sector and regions

Current codes[edit]

Subdivision names are listed as in the ISO 3166-2 standard published by the ISO 3166 Maintenance Agency (ISO 3166/MA).
