Additional information

House to flat conversions

To find out detail such as houses that have been converted to flats, you'll need AddressBase Plus. it includes current properties and addresses sourced from local authorities, Ordnance Survey and Royal Mail. These are all matched to the UPRN and structured in a flat-file model.

AddressBase Plus has more records than AddressBase as it includes objects without postal addresses such as places of worship and community centres - as well as sub-divided properties. It lets you locate an address or property on a map, through the assigned X and Y coordinates.

Crucially, the cross-referencing information with OS MasterMap products via Topographic Identifiers (TOIDs) means you can view address data within a wider geographic context.

Paying Royal Mail royalties as a commercial customer

Royal Mail royalties are included in the licence fee. A separate Royal Mail royalty fee applies if you license the AddressBase data on External Transaction Solution (ETS) terms.

File size

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.

Data from Royal Mail’s PAF

The database is a vital component of the single address gazetteer database and is in each of the AddressBase products where there has been a match confirming the address to the LLPG address.
