Postal/Zip Codes in the UK

Posting a letter in the UK? The post code numbers for all addresses that make up the towns and villages of England, Wales, Scotland and Northern Ireland...

The postal code system in the UK can pinpoint a location precisely and is therefore used for accurate information about location.

The system is made up of a series of 5, 6 or 7 letters and numbers:

  • A1 1AA
  • A11 1AA
  • AA1 1AA
  • AA11 1AA
  • A1A 1AA
  • AA1A 1AA

Postcodes/Zip Codes in London and the UK

The first letter or two letters indicate the general location. In London postcodes use the points of a compass making it is easy to know approximately where a building is:

  • E: East
  • EC: East Central
  • N: North
  • NW: Northwest
  • SE: Southeast
  • SW: Southwest
  • W: West
  • WC: West Central

Two 'compass' postcodes which are not in London are NE (Newcastle) and S (Sheffield). The only exception is for outer areas of London that actually fall within a county e.g. Twickenham (TW) or Bromley (BR). Although these addresses are in London boroughs, for address purposes they are not actually IN London.

The surrounding areas of London have the following postcodes:

  • BR - Bromley
  • CR - Croydon
  • DA - Dartford
  • EN - Enfield
  • HA - Harrow
  • IG - Ilford
  • KT - Kingston
  • RM - Romford
  • TN - Tonbridge
  • TW - Twickenham
  • UB - Uxbridge

Postcodes around the rest of the country begin with the letters of the local post office district, for example BT for Belfast, CF for Cardiff, EH for Edinburgh, and M for Manchester.
