Unique Property Reference Number (UPRN)

The Unique Property Reference Number is the United Kingdom’s persistent identifier for every addressable location — building, plot, parcel or subdivision. Issued by local authorities, curated by GeoPlace and published by Ordnance Survey, it is a stable numeric key that survives address changes, redevelopment and renaming. It underpins UK addressing, planning, conveyancing and property data, and is available under the Open Government Licence.

No provider in the catalog carries this standard as a tag yet. That is a statement about the catalog's tagging, not about adoption: a provider that implements UPRN and says so in its APIs.json profile appears here on the next build. Add or correct a listing.
