List of UK Postcodes and Towns

The list of UK Postcodes and Towns is an essential part of a mailing plan in the UK and is required to ensure mail is delivered accurately and quickly. Post Towns are usually based on the locations of sorting offices and are one of the elements which help to ensure an address is unique.

There are almost 1,500 Post Towns in the UK with each one covering one or more Postcode Districts and usually covering many more towns and villages.

Royal Mail state that the Post Town must be included on all mail items and that the name should be written or typed in capitals.
