Today’s guest blog is from Chris Chambers, our Address Portfolio Manager at Ordnance Survey.
Our AddressBase team has recently carried out detailed analysis of the 38,418,837 addresses in the AddressBase product suite to identify ‘postally addressable’ records. This work was based on our customers’ requirement to identify all properties within the AddressBase products that have the potential to receive mail, not solely the Royal Mail Postcode Address File (PAF) data contained within.
The result of this analysis was the identification of 30,463,892 ‘live postally addressable’ records in AddressBase Plus and an additional 654,379 ‘non-live postally addressable’ records in AddressBase Premium.
This is over 2 million more than the number of PAF records in ADDRESS-POINT, and over 1.1 million more than the number of Royal Mail PAF and Multi-Residence (MR) records contained within OS MasterMap Address Layer 2.
The piece of work has enabled us, for the first time, to confirm what we in the team have known for a while – that the AddressBase products are the most complete source of geographic address data for the nation. In conjunction with several customers, partners and GeoPlace, we have now created guidance which enables users of AddressBase Plus and Premium to identify these ‘live postally addressable’ records from existing products using a combination of attributes and values. However, a change to the rules used to populate a single field is being developed to make it simpler for customers to identify these records for themselves using a single attribute. We’re hoping that this change to product will be made this financial year.
