With OS Places API you have direct access to rich address data for geocoding, postcode searching, form-filling and much more. Find UK addresses instantly online and be confident you're getting the most up-to-date information.

The OS Places API provides a detailed view of an address and its life cycle. It contains all the records of AddressBase® Premium and AddressBase® Premium – Islands, that is it provides all the information relating to an address or property from creation to retirement.

OS Places API contains local authority, Ordnance Survey and Royal Mail® addresses, current addresses, and alternatives for current addresses, provisional addresses (such as planning developments) and historic information, plus OWPAs and cross references to the OS MasterMap® TOIDS®.

OS Places API includes addresses located within the United Kingdom, Jersey, Guernsey and the Isle of Man. For address records in Jersey and Guernsey the coordinates will be ‘0.0’ as they fall outside of the British National Grid. This means they are not compatible with the GeoSearch operations.
