AddressBase Plus
AddressBase Plus® contains current properties and addresses sourced from local authorities, Ordnance Survey and Royal Mail matched to the Unique Property Reference Number.
It has more records than AddressBase as it includes objects without postal addresses, such as subdivided properties, places of worship and community centres.
You can also locate an address or property on a map, by cross referencing the information with OS MasterMap® products.
Here AddressBase Plus is overlaid on OS MasterMap Topography Layer.
