OS AddressBase Plus

A comprehensive GB address database with advanced attribution

Along with Royal Mail PAF data, AddressBase Plus gives you up-to-date local authority addresses, multi-occupancy addresses and OS MasterMap TOID references. Accuracy is guaranteed with address information sourced from 380 local authorities across Great Britain, Ordnance Survey large-scale mapping, Royal Mail and the Valuation Office Agency.

OS AddressBase Premium

AddressBase Plus

AddressBase Plus contains current properties using addresses sourced from Local Authorities, Ordnance Survey and Royal Mail for England, Wales and Scotland. The product currently contains approximately 35 million records. OS AddressBase Plus is provided on a six week update cycle.

All address records are provided with an UPRN (Unique Property Reference Number), and the product contains all current addresses validated from Local Custodians and additional Royal Mail attribution where matched.

The product enables the end-user to locate an address or property on a map using either X & Y coordinates supplied on the British National Grid or Latitude and Longitude coordinates provided on an ETRS89 projection. The product also includes cross references to OS MasterMap Topography Layer TOID references.

Data enrichment with UPRN

OS AddressBase Plus can be used in any application which requires the precise location of an address. It can also be used to enrich records in your data with the Unique Property Reference Number (UPRN). UPRNs allows different databases to be connected based on a unique frame of reference – location.

Adding the UPRN to databases can help make deeper sense of data once it’s all linked together. Every property in Great Britain has a UPRN, and OS AddressBase Plus adds a precise location. This accurate and consistent reference system links people across multiple services, enabling data analytics and unlocking predictive insights that can underpin policy making.
