Just how accurate and affordable is PAF?

  • 29.5m
    UK addresses that can be delivered to across 1.8m postcodes

  • 4-5k
    updates a day, from thousands of postmen and women

  • License PAF for as little as
    per Postcode Area

These daily updates make PAF the UK’s most up-to-date address database. By taking advantage of daily updates you can get more letters and parcels to your customers first time. It also supports businesses in reducing abandoned baskets, expensive returns, fraudulent transactions and customer complaints. Saving you both time and money.

The cost of using our address and Postcode information is much lower than many people expect. For example, licensing the use of PAF in a single Postcode Area e.g. PO or SR, starts from just £2 per user, per year. There will be additional fees for the supply of the data or for the use of the Solution. You can find more information on prices and fees on our pricing page.
