National Address Gazetteer

The national address gazetteer brings together address information from local authorities and Ordnance Survey to create a ‘national address gazetteer database’, providing one definitive source of accurate publicly-owned spatial address data for the whole of the public sector. To deliver this, the Local Government Group and Ordnance Survey have entered into a joint venture partnership, ‘GeoPlace™’, from which address products have been created. It brings together local government’s address and streets gazetteers - the National Land and Property Gazetteer (NLPG), National Street Gazetteer (NSG) and One Scotland Gazetteer (OSG) - with all of Ordnance Survey’s addressing products - ADDRESS-POINT® and OS MasterMap® Address Layer and Address Layer 2. The national address gazetteer contains the existing unique identifiers and the definitive street name and number (generated by local authorities) with the postcode from the Royal Mail as well as a link to the map base from Ordnance Survey, through the OS TOID® and grid reference. The data contains the unique property reference number (UPRN) and unique street reference number (USRN) from the NLPG and OSG as the primary keys.
