AddressBase product family
Match millions of Royal Mail postal address to unique property reference numbers (UPRN), bringing a geographical dimension to the connected records
What is AddressBase?
The AddressBase product family is made up of four products:
- AddressBase
- AddressBase Core
- AddressBase Plus
- AddressBase Premium
AddressBase products are created by bringing together different address sources:
- Local Authority Gazetteers for England, Wales and Scotland
- Royal Mail Postcode Address File (PAF) data
- References to Valuation Office Agency (VOA) data
- Additional addresses and coordinates from Ordnance Survey
This information is managed by GeoPlace under partnership between Local Government Association and Ordnance Survey (OS). Scottish Local Authority address information is supplied under licence between OS and the Improvement Service supported by the Scottish Government.
AddressBase family features
Unique references
Each address has a Unique Property Reference Number (UPRN), which is the persistent identifier regardless of any changes made to the address to allow ease of data management and exchange of data.
Granular address details
Gain intelligence about an address with an extensive range of attribution at individual property level such as the type of address. Look up addresses on a database of millions, quickly and efficiently.
Geocoded PAF records
Every address geo data record provides Royal Mail address information from PAF, the Unique Delivery Point Reference Number (UDPRN) and X and Y coordinates.
