ISO 3166-2:GB

Last updated December 06, 2024

ISO 3166-2:GB is the entry for the United Kingdom of Great Britain and Northern Ireland 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.^[1] The codes and structures used are provided to the ISO by British Standards and the Office for National Statistics.

Current codes

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

BS 6879 gives alternative name forms in Welsh (cy) for some of the Welsh unitary authorities (together with alternative code elements). Since this part of ISO 3166 does not allow for duplicate coding of identical subdivisions, such alternative names in Welsh and code elements are shown for information purposes only in square brackets after the English name of the subdivision.^[1]

Countries and province

Code	Subdivision name (en)	Subdivision category
GB-ENG	England	country
GB-NIR	Northern Ireland	province
GB-SCT	Scotland	country
GB-WLS	Wales [Cymru GB-CYM]	country

Wales was changed from being described as a principality to being described as a country in the December 2011 update to the standard. England and Scotland were maintained as country and Northern Ireland was maintained as province.^[3]

Included for completeness

GB-EAW	England and Wales

The United Kingdom, a sovereign state to the northwest of continental Europe, consists of England, Northern Ireland, Scotland and Wales.

Consequently, there is "no common stratum of administrative unit encompassing the United Kingdom".

The terminology of the British Isles comprises the words and phrases that are used to describe the geographical and political areas of the islands of Great Britain and Ireland, and the smaller islands which surround them. The terms are often a source of confusion, partly owing to the similarity between some of the actual words used but also because they are often used loosely. Many of the words carry geographical and political connotations which are affected by the history of the islands. The inclusion of Ireland in the geographical definition of British Isles is debated. Ordnance Survey Ireland does not use the term.
