AddressBase Plus

Along with Royal Mail PAF data, AddressBase® Plus gives you up-to-date local authority addresses, multi-occupancy addresses and OS MasterMap TOID references.


Individual address referencing

For direct marketing teams: take your data analysis to the next level by referencing data to individual addresses (such as flats) rather than mail delivery points (houses divided into flats).


Easy-to-use, 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.

Easy cross-referencing
