National Statistics Postcode Lookup (February 2026) For The UK (Hosted Table)

This is the National Statistics Postcode Lookup (NSPL) for the United Kingdom as at February 2026 in Comma Separated Variable (CSV). This is a new hosted table so can be accessed via API. The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2021 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations) for England, Wales, Scotland and Northern Ireland. It supports the production of area-based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly.
