Faster look-ups and better analysis
Addressible is a GB dataset that combines Royal Mail’s Postcode Address File (PAF), Multi-Residence File, Alias File and Welsh Language addresses with location coordinates (X/Y and Lat/Long), topographical identifiers (TOIDs) and Unique Property Reference Numbers (UPRNs). Use it in internal systems, or in an address lookup service.
