ISO 3166-2:GB

ISO 3166-2:GB is an International Organization for Standardization (ISO) coding system that gives geocodes to administrative divisions of the United Kingdom:

• England
  • 34 counties with county councils (all shire counties except Berkshire)
  • 32 London boroughs
  • 36 City Sections
  • 47 Large Areas (including the Isles of Scilly)
  • 1 city corporation (the City of London)
• Northern Ireland
  • 26 Subdivisions of Northern Ireland
• Scotland
  • 32 Council Areas of Scotland
• Wales
  • 22 Unitary Authorities of Wales

The Channel Islands and the Isle of Man are not part of the UK, but ISO offers codes for them under "GB-".

The first part of each code is the ISO 3166-1 code GB for the United Kingdom. The second part is a three-letter code which is the same as in the British Standard BS 6879.
