Marketing is expensive - don't waste money on mailing to inaccurate addresses. We use the Royal Mail Address File, the UK's most up-to-date address database, with over 30 million postal addresses.
The Royal Mail Postcode Address File (PAF) is the definitive list of deliverable UK addresses. Validating against it means every address on your list is real, correctly formatted and deliverable.
Use PAF validation to clean an existing database or to auto-complete and verify addresses at the point of capture, so campaigns never fail on a bad address.
Validate against the UK's most complete address database.
Keep addresses that Royal Mail can actually deliver to.
Never pay to mail an undeliverable address again.
