Driving improvement, excellence and innovation through data

GeoPlace® is a public sector limited liability partnership between the Local Government Association and Ordnance Survey. Our vision is to be the recognised centre of excellence for spatial address and street information management in Great Britain.

GeoPlace's role is to create and maintain the National Address Gazetteer and the National Street Gazetteer for England and Wales, providing definitive sources of publicly-owned spatial address and street data. AddressBase™ products are produced from the National Address Gazetteer and made available by Ordnance Survey.

Through agreement with Scotland's Improvement Service Company, coverage has been extended to include Scotland.
