AddressBase Premium

Our flagship address database, AddressBase® Premium gives you up to date, accurate information about addresses, properties and land areas.


Over 40 million addresses

AddressBase Premium has over 40 million addresses and 100 million cross references as well as providing all the information relating to an address from creation to retirement.

Efficient processes

Each address is referenced by the Unique Property Reference Number (UPRN), a persistent identifer for each address allowing you to manage addresses throughout their lifecycle and making your processes more efficient - meaning it easier to deliver a smooth service to your customers. 

Shape your operations

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.

Spot data patterns

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.

Addresses throughout the property lifecycle

Addresses throughout the property lifecycle

The AddressBase Premium dataset contains Local Authority, Ordnance Survey and Royal Mail addresses, each uniquely referenced by the UPRN.

This includes addresses throughout the property lifecycle; from proposed planning development through to demolished address. This includes alternative addresses for current records where available, indicating variations on the official addresses and/or addresses in different languages (Welsh or Gaelic).

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.
