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 37 million records.
The product contains all current addresses validated from Local Custodians and non-postal addresses such as ponds, electricity sub-stations and telephone boxes are also included.
The product enables the end-user to locate an address or property on a map using either X, Y coordinates supplied on a British National Grid or Latitude and Longitude coordinates provided on an ETRS89 projection, and display the Local Authority address elements or the Royal Mail address elements where matched.
Flat file model
AddressBase Plus is structured in a flat file model – containing current properties and addresses sourced from local authorities, Ordnance Survey and Royal Mail matched to the UPRN.
Accuracy guaranteed
The address information is sourced from 380 local authorities across Great Britain, our own large-scale mapping, Royal Mail and the Valuation Office Agency.
Useful addresses
As well as 28 million defined properties, Ordnance Survey have included more than 7 million local authority addresses, such as depots and church halls, places of worship and community centres.
Property classification
Understanding the need to categorise properties, Ordnance Survey incorporated a four-level classification scheme that explains the function of each property.
