Unique Property Reference Number

The Unique Property Reference Number (UPRN) is a unique numeric identifier for every spatial address in Great Britain. It is created by local authorities who have the statutory authority to name and number every street and property and Ordnance Survey who identify objects on the landscape which may not otherwise have a postal address.

This website allows you to look up all the publicly available data for any UPRN in Great Britain. Simply put the UPRN into the search box to see all the information we have for that UPRN. Alternatively, search for a postcode to see all the UPRNs in the immediate vicinity.

A UPRN is an all-numeric identifier of up to 12 digits long.
