National Land and Property Gazetteer

The National Land & Property Gazetteer or NLPG is a database of land and property in England and Wales. It is part of the United Kingdom's e-government programme, which aims to increase the range of official transactions that can be conducted online. Initial uses of the gazetteer include the following:

The structure of the database is defined by the BS 7666 standard (see British Standards). This includes the concept of a 12-digit Unique Property Reference Number (UPRN) for every building and plot of land in the country.

Formerly, postal addresses and postcodes were used to identify properties for official purposes, but the NLPG allows the identification of properties without postal addresses.
