OS Open Linked Identifiers is a dataset containing the authoritative relationships between Unique Property Reference Numbers (UPRNs), Unique Street Reference Numbers (USRNs) and Topographic Object Identifiers (TOIDs). Watch our OS Open Linked Identifiers introduction video.
Connecting addresses with road features enables more related data to be joined together which simplifies a number of valuable workflows. Linking these features to graphical elements of OS MasterMap products enables better visualisation of the data related to them.
Link data related to an address with its building footprint. Validate an addresses UPRN with the name of the road that accesses it. Validate a streets USRN with the name of the road it relates to.
The relationships UPRN and USRN are provided by the bodies responsible for the identifier schemes; and these are spatially matched to OS MasterMap features by Ordnance Survey. This means you can have confidence you're accessing an authoritative source of these relationships.
The relationships are taken from our premium data products and being made open for the so everyone can access them from one trusted source.
