What is PAF Address Cleansing ?
PAF Postal address cleansing is the process of verifying the postal addresses of your customers or contacts against the Royal Mail Postcode Address file (PAF).
PAF is the complete reference database containing all UK residential & business postal address information. It's updated with new addresses & amended postcodes on a daily basis so is fully up-to-date.
Address cleansing is an essential primary component for Data Cleansing and can also vastly improve your Deduplication results.
How does Address Cleansing Work ?
Matching against PAF will:- Update address components such as postcode changes
- Correct spelling mistakes & keystroke errors
- Add missing address elements
- Standardise the format of the postal address

Did you know?
Postal addresses with minimal information may not successfully verify against PAF.
In some cases it's possible to complete them with manual intervention.
This can be a beneficial tool if your contact data is of a sensitive nature or your customers are especially valuable.
