How do I get hold of UPRNs and USRNs?

GeoPlace manages the National Address Gazetteer that Ordnance Survey uses to publish the AddressBase range of products and the new OS Open UPRNs. We also maintain the National Street Gazetteer, the primary source for USRNs.

We supply USRNs to OS, so that they can create the OS MasterMapĀ® Highways Network and include USRNs in the new OS Open USRN product.

You can find out more about these at -

All of these datasets are available free of charge to the public sector under the Public Sector Geospatial Agreement.

What are UPRNs and USRNs?

UPRNs and USRNs are unique identifiers - codes - for physical objects and places.

A Unique Property Reference Number (UPRN) is a unique, numerical identifier. There's one for every addressable location in Great Britain - structures like houses, or objects that must be identified accurately, like lamp posts.

Similarly, a Unique Street Reference Number (USRN) is a unique, numerical identifier. There's one for every street across Great Britain and, once allocated, a USRN never changes.

From planning, right through to demolition, UPRNs and USRNs never change. This means that you can guarantee the information in different databases matches, whenever there's a location involved

Why is GeoPlace best placed to help?

GeoPlace is the central co-ordinator for UPRNs and USRNs in Great Britain. Our expertise in managing and using these unique identifiers is unparalleled.

We're the experts. And we're here to share our expertise.
