National Statistics UPRN Lookup (February 2021)

<p><span style='color:#4C4C4C; background:white;'>This file contains the National Statistics UPRN Lookup (NSUL) for Great Britain as at February 2021. The NSUL relates the Unique Property Reference Number (UPRN) for each GB address from AddressBase® Epoch 81 to a range of current statutory administrative, electoral, health and other statistical geographies via 'best-fit' allocation from 2011 Census output areas (National Parks and Workplace Zones are exempt from 'best-fit' and use 'exact-fit' allocations). The NSUL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSUL is issued every 6 weeks and is designed to complement the Ordnance Survey AddressBase® product.
