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.


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.

How is this data supplied and what do I need to use it?

AddressBase Plus is supplied on DVD. If the file size of your order is smaller than 2Gb, you can get it from our FTP server. In addition, public sector customers can download 5km chunk orders via our download service.

You'll need geographic information system (GIS) software to use AddressBase Plus.

What's the advantage of AddressBase Plus over AddressBase?

AddressBase contains Royal Mail PAF addresses and assigns an x and y coordinate to every address. This lets you carry out only relatively basic analysis.

AddressBase Plus also includes current properties and addresses sourced from local authorities, Ordnance Survey and Royal Mail. Records are matched to the UPRN and structured in a flat-file model.

AddressBase Plus holds more records than AddressBase as it includes objects without postal addresses, such as subdivided properties, places of worship and community centres. It also allows the end-user to locate an address or property on a map, through the assigned x and y coordinates.

Crucially, cross-referencing the information with OS MasterMap products via the OS MasterMap Topography Layer and Integrated Transport Network (ITN) Layer Topographic Identifiers (TOIDs) lets you view address data within a wider geographic context.

How often is AddressBase Plus updated?

We release updates every six weeks, which we call Epochs (view release schedule). The update is made available to customers for managed sets and areas of interest as full supply or as change-only updates (COU).

Do properties yet to be built appear in AddressBase Plus?

No. You'd need to buy AddressBase Premium for this information. It's ideal when you're planning the future provision of infrastructure services such as sewerage or high-speed broadband.
