AddressBase Plus support

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. 

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.

We release updates every 6 weeks, which we call Epochs. The update is made available to customers for managed sets and areas of interest as full supply or as change-only updates (COU).

No. You'd need 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.
