On the 2nd
of April 2020, the Government announced that the Unique Property Reference Number (UPRN) and Unique Street Reference Number (USRN) will be released under Open Government Licence. Additionally, the Open Standards Board, via Government Digital Service (GDS), has mandated that from 1st July 2020, the UPRN and USRN are the public sector standard for referencing and sharing property and street information.
"The availability of the UPRN and USRN as Open Data, and the approval as Open Standards by the Standards Board, represents a step change in the referencing of property and street information and supports GeoPlace’s vision where ‘everyone benefits from the power of location data’. The adoption of these identifiers across the public sector provides a platform for transformation and efficiency through the way location data is managed, linked, shared and used."
Steve Brandwood – Executive Director of Engagement at GeoPlace
Publish reference data for use across government
Additionally, on 11th March 2021, the Government Digital Service provided best practice guidance for creating a strategy to manage and support reference data for publishing. The guidance is aimed at government employees who need to publish reference data so others can use it across government.
The guidance specifically highlights the use of UPRNs. See https://www.gov.uk/guidance/publish-reference-data-for-use-across-government.
