What is the Royal Mail Postcode Address File?

18 Sep 2020, 22:07 ... ress-file/

The Royal Mail Postcode Address File (PAF) is an up-to-date address database, containing over 30 million UK postal addresses. It has numerous benefits, such as helping to verify addresses in seconds, making online transactions easier and ensuring that mail is delivered efficiently.

This is why PAF is an integral part of Ordnance Survey’s AddressBase. Combining the postal data of millions in the UK with local authority data, Unique Delivery Point Reference Numbers (UDPRN) and X and Y coordinates allows organisations to provide professional services to their customers, helping to increase the number of online sale conversions and lessening the risks of fraud.

Maintaining reliable information

With approximately 90,000 postal workers covering all of the UK’s streets six days a week, Royal Mail are consistently being informed of any changes to addresses and it is estimated that their input contributes to between 3,000-5,000 changes made to Royal Mail’s database every day. Further to this, PAF holds a staggering total of 30,828,292 delivery points across the UK – that’s a lot of address based data!

Having access to reliable postal information is instrumental for any business that takes pride in customer service. So, in order to ensure that information is as accurate and simple to analyse as possible, Royal Mail’s PAF data has been enhanced with Ordnance Survey’s detailed property data, UPRN’s, GeoPlace data and local authority data to form a product called AddressBase.
