AddressBase Premium provides the most detailed view of an address and its lifecycle for England, Wales and Scotland. It has approximately 40 million addresses as it records an address from creation through to retirement. All address records are provided with a Unique Property Reference Number (UPRN).
This product is updated every six weeks.
There are over 100 million cross references which include references to VOA data and products such as OS MasterMap Topography Layer and OS MasterMap Highways Network are also included.
The product contains Local Authority, Ordnance Survey and Royal Mail addresses. This includes alternative addresses for current records where available, indicating variations on the official addresses and / or addresses in different languages (Welsh or Gaelic); as well as including provisional addresses (proposed planning developments), and historic information (demolished properties) where available. Other addresses known as Objects Without a Postal Address (OWPAs) are also included in AddressBase Premium, these include places of worship, community centres and utilities.
The AddressBase Premium dataset contains Local Authority, Ordnance Survey and Royal Mail addresses, each uniquely referenced by a UPRN (Unique Property Reference Number).
Property level coordinates within AddressBase Premium allow you to conduct analysis at the level of individual addresses and spot patterns hidden in your own data.
With UPRNs being assigned as soon as planning permission is granted, with AddressBase Premium you'll have all the information you need to shape the way you plan, operate and communicate with your audience.
Each address is referenced by a UPRN, a persistent identifier for each address, allowing you to manage addresses and making your processes more efficient.
