Authority Address and Authority Street Custodians

Authority Address and Authority Street Custodians are vital to the success of GeoPlace, the AddressBase products and the National Street Gazetteer.

The local authorities capture and maintain address and street change intelligence, each with a Unique Property Reference Number (UPRN) or Unique Street Reference Number (USRN) and send GeoPlace over 5,000 update files per month. Across local authorities as a whole, there are around 2 million records modified and sent to GeoPlace each month.

Dedicated resources to help Authority Address Custodians are available on the NLPG website whilst resources for Authority Street Custodians can be found on the NSG website.
