About the IPN

The IPN is a gazetteer linking over 70,000 named places in England and Wales to their respective administrative, health and electoral areas.

It also relates places to registration districts, built-up areas and national parks.

We provide a 1-metre grid reference, and where the place has legally defined boundaries, a re-aggregated 2011 Census population count.

The places for which we give information include administrative units (ranging from parishes to regions (former GORs)), localities and urban areas/subdivisions.

From 1 January 2011, the new GSS Coding and Naming policy for some statistical geographies was implemented.

So, where new codes have been allocated, you should use them in all exchanges of statistics and published outputs that normally include codes.

The Code History Database (CHD) provides multi-functionality, including details of all codes, relationships, hierarchies and archived data.

The 2018 IPN contains the nine-character GSS coding for all geographies, except localities, settlements, urban areas and urban subdivisions.

Product details

The IPN is an MS Access 2007 file, with accompanying XML metadata and user guide.
