This file contains the National Statistics UPRN Lookup
(NSUL) for Great Britain as at December 2016. The NSUL relates the Unique
Property Reference Number (UPRN) for each GB address 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 'Product Specification' document contained
