This file contains the National Statistics UPRN Lookup (NSUL)
for Great Britain as at June 2017. The NSUL relates the Unique Property
Reference Number (UPRN) for each GB address from AddressBase® Epoch 49 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. 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
