Address data questions and answers
How is OS addressing data different from Royal Mail?
The AddressBase products combine Royal Mail’s Postcode Address File (PAF), local authority address data and Ordnance Survey’s in-depth, property level data to create the most comprehensive dataset available.
We add a Unique Property Reference Number (UPRN) and geographic location to each property, making the data easier to analyse and offering so much more than just a postcode lookup solution.
How are the products created?
Address data is constantly maintained on a frequent basis and managed by GeoPlace, the data specialist at the heart of a complex ecosystem that produces our National Address Gazetteer. This includes over 40 million addresses and 1.45 million streets.
Bringing elements from local authority, Royal Mail and Ordnance Survey together means that AddressBase is the nation’s most authoritative, current, and accurate data. AddressBase is the only addressing you need to be assured of working with the ‘single point truth’, in every situation.
