Geography tables (February 2025)

We’ve published the latest geography lookup table (February 2025) to help you understand which local authority, ward or local health board a postcode is in.

The table contains the names and identification codes of Welsh statistical geographies, from postcode through to local health board, and how they relate to each other.

The data will be updated quarterly following a release by the Office for National Statistics (ONS).
