Description

The definitive Postcode database which includes all Postcodes for the United Kingdom (England, Scotland, Wales and Northern Ireland) with their respective 6 figure OSGB grid references and Longitude and Latitude.

The Great Britain (England, Scotland and Wales) data is sourced from the latest Ordnance Survey Code-Point© Open data and Northern Ireland grid references are sourced from the latest Royal Mail information.

About the Grid References

Great Britain grid references are taken from Ordnance Survey Code-Point OpenData. These 6 figure grid references are based upon the British National Grid System and measure Postcode locations in metres from the national (0, 0) point of origin.

For the most accurate PQI’s, these grid references indicate the location to 1 metre accuracy of the first building within the Postcode.

As Ordnance Survey only provide data for Great Britain (England, Scotland & Wales), grid references for Northern Ireland (Postcodes starting with BT) are taken from Royal Mail Postzon data. These grid references are on average accurate to approximately 100 metres and are therefore less accurate than the grid references provided for Postcodes across Great Britain.

All grid references have also been converted and supplied as Latitude and Longitude decimal co-ordinates within the same file.
