Role of Addresses within Local Authorities

Vital to the success of building and maintaining the AddressBase products is working closely with those local authorities that have a street naming and numbering duty. They provide frequent updates to the central hub at GeoPlace with new address and street information.  Additional information is also brought in by GeoPlace from the Valuation Office Agency, Royal Mail and Ordnance Survey.

Local Authorities have a statutory duty to provide Street Naming and Numbering (SNN) information. This duty requires that all streets are named and properties numbered as local authorities are the legal source of this information.

A Street Naming and Numbering Officer within a local authority manages this process. The Address Change Intelligence (ACI) that they compile in their role feeds into the creation and maintenance process of a Local Land and Property Gazetteer (LLPG) that contains addressing information for their administrative area. 

LLPG’s are managed by a LLPG Custodian who creates and maintains address records at a local level to an agreed methodology defined by GeoPlace and elected regional representatives from the local government community.  Their LLPG is then passed to the hub (managed by GeoPlace) which tests its conformance to the agreed Data Entry Conventions based on BS7666 (2006) Parts 1 & 2. 

For further information on address creation within Local Authorities visit the GeoPlace website.
