A Unique Property Reference Number (UPRN) is a unique numeric identifier for every addressable location in Great Britain, found in OS's AddressBase products. An addressable location may be any kind of building, residential or commercial, or it may be an object that might not have a ‘postal ’ address – such as a bus shelter.
UPRNs are the authoritative identifier used to uniquely identify addressable locations in Great Britain. Essential for bringing property and address information together.
OS Open UPRN will enable you to share and link data related to UPRNs, which you can visualise using the accurate location.
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 never re-used, once its allocated to an address record, that’s it, it will never change or be reused.
