you’ve found.

Behind your search

Real places.
Clear sources.

Postcodes

ONS Postcode Directory

Find a postcode on the map and check when it was introduced or retired. Your location marks the centre of a postcode area, rather than a particular building.

About the postcode source
Addresses

OpenStreetMap

Search addresses with a recorded postcode on OpenStreetMap. Your result may mark a mapped address, a linked property point, or the centre of its postcode area.

About OpenStreetMap
Property locations

OS Open UPRN

When an address includes a property reference (UPRN), you can get a matching property location from OS Open UPRN. A property reference on its own doesn’t supply an address.

Coverage

Great Britain.

You can look up postcodes across England, Scotland and Wales. Address search covers the places recorded in OpenStreetMap, so availability varies by location.

Check what your pin means. A postcode pin marks the centre of an area. A property pin is more specific, but its position can still be approximate.

Allow for missing addresses. OpenStreetMap doesn’t record every postal address. If you need complete postal validation, choose an appropriately licensed address product.
