OS Open UPRN
An open dataset enabling linking, sharing and visualisation of data related to Unique Property Reference Numbers (UPRNs).
UPRNs are the authoritative identifier used to uniquely identify addressable locations in Great Britain; they are essential for bringing property and address information together.
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. The addressable location may also be an object that might not have a ‘postal ’ address – such as a bus shelter or an electricity sub-station.
Share and link data
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.
