Coverage

Royal Mail forms part of the process when an address is created, meaning that street name information relating to new developments is received from Local Authorities and registered onto Royal Mail’s NYB file whilst being assigned a postcode. This instant download contains all circa. 706,940 Not Yet Built (NYB) UK wide addresses / delivery points that are currently under construction or in the planning stage.   Royal Mail works with each UK authority, supporting planning departments, to define street names and postcodes – preparing them for delivery / post distribution.  The file is the only comprehensive national and central single source database of its type.  As the file focuses on NYB properties it does not include properties that are already built; these can be found on Royal Mail’s Postcode Address File (PAF), which is an additional dataset.
