List of postal areas in the United Kingdom
The UK postal system runs on a system of alphanumeric codes, or Postcodes. Each postcode begins with a prefix consisting of one or two letters. Normally this prefix, the postal area denotes the main sorting office through which the post for that place is filtered before being distributed to individual addresses; the only exception to this rule is with postcodes in the inner London area (but this does not correspond completely to other definitions of inner London).
Note that the postcodes, and also the full postal addresses, do not follow local government or traditional county boundaries. The London postal districts cover a much smaller area than the Greater London Authority and many areas in outer London have non-London postcodes, eg. UB - Uxbridge.
Postal counties are no longer required by Royal Mail; and if a postcode is supplied, the county will be ignored. Many people will still quote their address using them, however.
See also List of postal districts in the United Kingdom for a list of the 2900 districts, for example UB40.
