List of postcodes in the United Kingdom

Template:Postcode areas imagemap

There are approximately 1.7 million postcodes in the United Kingdom (including the Channel Islands and the Isle of Man).[1]

Each postcode is divided by a space into two parts. The first part of a UK postcode is known as a postcode district. Postcode districts with the same one or two letter prefixes are grouped into postcode areas. The second part of a postcode begins with a single digit which indicates the postcode sector within each district.

Postcode areas are also divided into several post towns, which predate the introduction of postcodes, with the London post town uniquely covering more than one postcode area.

As of August 2012, there are 124 postcode areas, 2,987 postcode districts, 11,192 postcode sectors, and 1,662 post towns.[1] Addresses receiving large volumes of mail are each assigned separate "large user" postcodes. But most postcodes are shared by several neighbouring properties, typical covering about 15 addresses.


The Address Management Unit of Royal Mail maintains an official database of UK postal addresses and postcodes on its Postcode Address File (PAF), which is made available under license for a fee regulated by Ofcom.

On its Postcode Finder website, but this is limited to 15 free searches per user per day.

A complete list of all Great Britain postcodes, known as Code-Point Open, is made available online without charge by Ordnance Survey, under the government's OS OpenData initiative. The Code-Point Open list includes median coordinates for each postcode but excludes postcodes in Northern Ireland and the Crown dependencies. Unlike the PAF products provided by Royal Mail, the Code-Point Open list does not include postal address text.
