This website started life as a spin-off from Check My Postcode. I had originally intended to include UPRNs in the data supplied with postcodes, but that turned out to be impractical due to the large quantity of data contained within the UPRN datasets.
UPRN.uk combines the two primary open data sources of UPRN information, the Office of National Statistics and Ordnance Survey, into a single database that allows you to look up the public data for any UPRN.
This is very much a work in progress, and new features and more data will be added in future.
