What is the National Address Gazetteer Database?

The National Address Gazetteer is a database set up to provide a source of publicly-owned spatial address data from local authorities and Ordnance Survey for the United Kingdom. The dataset is an amalgamation of both Local Land and Property Gazetteers (collectively known as the National Land and Property Gazetteer: as well as the National Street Gazetteer (NSG) and One Scotland Gazetteer (OSG). Added together, this results in a definitive street name and number, postcode as well as a Unique Property Reference Number (UPRN) as a primary key.
