The National Spatial Address Infrastructure (NSAI) was a database proposed by the UK Office of the Deputy Prime Minister (ODPM) on 26 May 2005 with the intention of creating a single repository of addresses for the UK. The proposal encountered numerous objections, particularly from local authorities who argued that such a repository already existed in the form of the National Land and Property Gazetteer (NLPG). Currently proposals for the NSAI have been suspended.
