What OS Open UPRN provides you with

Unique Property Reference Number

A Unique Property Reference Number (UPRN) is a unique numeric identifier for every addressable location in Great Britain, found in OS's AddressBase products.

Addressable features

UPRNs are assigned to approximately 40 million addressable locations, which may be any kind of building; residential or commercial. It may also be an object that might not have a ‘postal ’ address – such as a bus shelter or electricity sub-station.

OS Open UPRN will enable you to share and link data related to UPRNs, which you can spatially analyse and visualise using the accurate location.

Authoritative source

The UPRNs in OS Open UPRN are primarily allocated by Local Authorities, under their legal duty to maintain this information. This means you can have confidence you're accessing an authoritative source of these identifiers.

Identifiers you can trust

The UPRN is a persistent identifier to an addressable location that is never re-used, allowing you to confidently manage associated information to an address.

Use cases

OS Open UPRN enables users to:

Share information held against a UPRN with a location
Link together information associated with UPRNs
