About Postcodes UK

Postcodes UK is a free geographic reference site dedicated to the United Kingdom postcode system. Our editorial team researches and writes guides covering postcodes, distances, centroids and the tools that make location data accessible to everyone.

We combine Ordnance Survey data, Royal Mail postcode records and government open data to build a comprehensive picture of every postcode, town and county across England, Scotland, Wales and Northern Ireland.

Our goal is to make UK geographic data simple, accurate and freely available. Every article we publish is grounded in the datasets that power the site, and every distance, coordinate and boundary we reference has been verified against authoritative sources.

Data Sources & Credentials

  • Experienced in Ordnance Survey open data
  • Created Royal Mail PAF data integrations
