Data has the power to transform lives

Excellent addressing and accurate street data has the power to transform people’s lives.

In Great Britain, GeoPlace is the guardian and champion of that information on a national scale.

Authoritative UK geospatial address and street data

GeoPlace is a limited liability partnership owned equally by the Local Government Association (LGA) and OS. We are responsible for collating, managing and maintaining the primary UK authoritative geospatial address and street data.

GeoPlace is recognised world-wide as an established expert in managing address data and its associated infrastructure. We do this to a standard and in a way that inspires innovation and transforms people’s lives on a national scale.
