**Addresses throughout the property lifecycle**

The AddressBase Premium dataset contains Local Authority, Ordnance Survey and Royal Mail addresses, each uniquely referenced by a UPRN (Unique Property Reference Number).

**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.

**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.

**Enable efficient processes**

Each address is referenced by a UPRN, a persistent identifier for each address, allowing you to manage addresses and making your processes more efficient.
