The question

To ask the Secretary of State for Science, Innovation and Technology, whether there is a unified Unique Address Reference Number (UARN) or Unique Property Reference Number (UPRN) for residential dwellings in (a) England and (b) Wales.

Answered by Ian Murray

Unique Property Reference Numbers (UPRNs) are in place for residential (and other forms) of properties in England and Wales. Unique Address Reference Numbers (UARNs), as supplied by HMRC, are linked to Ordnance Survey address data products. The data is made available under license through the OS Data Hub, including free at the point of use data to public sector users through the Public Sector Geospatial Agreement (PSGA).
