This file contains the National Statistics UPRN Lookup (NSUL)
for Great Britain as at June 2019. The NSUL relates the Unique Property
Reference Number (UPRN) for each GB address from AddressBase® Epoch 67 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 12 weeks and is
designed to complement the Ordnance Survey AddressBase® product. For further
technical information about this file, please refer to the User Guide document
contained within the downloadable zip file. Please note that this product
contains Royal Mail, Gridlink, Ordnance Survey and ONS Intellectual Property
Rights. (File Size – 399 MB)
