What AddressBase Plus provides you with

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 seven 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.
