A Unique Street Reference Number (USRN) is a unique and persistent identifier for every street, road, track, path, cycle track or cycle way in Great Britain.
This product is updated monthly
Our Open USRN product contains USRNs across GB. They are the authoritative identifier assigned to and uniquely identifying streets and are essential for managing Great Britain's Highways. Once its allocated to a street record, a USRN will never change or be reused.
The USRNs in OS Open USRN are allocated by Highway or Road Authorities and Highway Bodies, under their statutory responsibility to maintain this information. This means you can have confidence you’re accessing an authoritative source of these identifiers.
All USRNs present in OS MasterMap Highways Network, are also included in this product – so you can be sure you’re not missing out.
OS Open USRN will enable you to start sharing and linking together information about USRNs which you can visualise with a location.
