OS Open Linked Identifiers
OS Open Linked Identifiers provides authoritative relationship between UPRNs, USRNs, TOIDs and meta data to enable reliable matching; for greater data connectivity.
This product is updated every six weeks
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.
The OS Open Linked Identifiers product provides the valuable relationships between the following features found in OS MasterMap products (TopographicAreas limited to address and road features):
*restricted to address and road features.
Open Linked Identifiers includes the latest version information for all the respective features that are referred to. In some cases, this might be a different version of the feature than what was used to form the relationship. This means that in some cases the relationship might not still be valid. To help resolve this we’ve also included a confidence value, indicating if the feature has changed since the relationship was formed, which can be used to resolve errors.
Geometry is not included in OS Open Linked Identifiers. You can get the geometry you need from either OS Open UPRN, OS Open USRN or OS Open TOIDs.
OS Open Linked Identifiers does not contain UDPRN, as there is 3rd party IP associated with the UDPRN.
