A professional body for residential property managers has called on the Government to promote the wider adoption of the unique property reference number (UPRN). The Institute of Residential Property Management (IRPM) has published an open letter to Housing Minister Robert Jenrick and director of the Geospatial Commission Thalia Baldwin outlining a number of steps it believes should be taken. UPRNs provide unique identifiers for each address in the country. They are allocated by local authorities and managed nationally by GeoPlace – a joint venture of the Local Government Association and Ordnance Survey – and can be used as a key feature in matching different datasets for service delivery and planning.
