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.
Ordnance Survey's Open Unique Property Reference Product will enable you to share and link data related to UPRNs, which you can visualise using the accurate location.
UPRNs are the authoritative identifier used to uniquely identify addressable locations in Great Britain. Essential for bringing property and address information together.
