Listening to our customers, Ordnance Survey has developed the first definitive address register for the UK and Crown Dependencies. This means our customers will have their geographic addressing needs for the whole of the UK and Crown Dependencies met by one supplier. Existing users of AddressBase can simplify their Address Management by using one format and data tables saving time ingesting and maintaining address data. The product also provides the UPRN for an additional 1 million records with the same attribution contained in AddressBase products, such as the location (latitude & longitude of the address).
