Where does the UPRN come from?
UPRN ranges are centrally allocated and managed by us. We provide each local authority with a range of UPRNs for them to allocate as needed.
Local authorities' statutory responsibilities mean that they are the source of information within a property's lifecycle and are responsible for assigning UPRNs for each address record. Guidance to local authorities states that UPRNs should be entered against a record as soon as ‘Construction' begins or ‘street naming and numbering' has been carried - out whichever is earliest.
Activities such as street naming and numbering, planning applications, building and environmental control, licensing, electoral registration, council tax and nondomestic ratings repeatedly bring local authorities in contact with land and property enabling thorough management of its lifecycle.
