Postcode Address File

paf royal mail logoThe most complete and up-to-date address database in the UK, containing the full address for every place the Royal Mail delivers to in the UK (over 27 million addresses).

The Postcode Address File (PAF) from the Royal Mail is the most up-to-date and complete address database in the UK, containing over 28 million addresses. PAF is an invaluable tool for creating and maintaining mailing lists and databases, as well as reducing the number of returned or undelivered items. PAF is the only complete source of all known UK Postcodes.

The data is owned and meticulously maintained by the Royal Mail's army of postal workers who are continually feeding data into the process to make PAF the most accurate national gazeteer anywhere in the world.

Address Validation techniques are now common place so that entire addresses can be captured quickly and accurately with only a few key strokes. The file is also invaluable to marketers wanting to ensure that their address data is postally correct prior to performing a mailshot in order to achieve maximum response rates and minimise returns - and also the mailsort savings that well addressed data can obtain.
