Gridlink® is the brand name for the joint approach to creating postcode location products. These products relate unit postcodes to geographic areas, such as electoral wards and health areas, and also provide postcode 1m grid references. The Gridlink® consortium comprises the Office for National Statistics (ONS), Ordnance Survey, Royal Mail, National Records of Scotland and the Ordnance Survey of Northern Ireland.
In the past, competition between different organisations had led to duplication of effort on postcode products and also to variation in methodology and consistency of the actual outputs. Gridlink® ensures a standard and consistent approach to postcode referencing products in the UK.
