The improvement and cleansing of addresses reduces undeliverable mail and can improve mailing discounts. Correct addressing can also maintain your brand image and the chances of identifying duplicates within your database. 

Our advanced Address Cleansing service compares your address data against Royal Mail's Postcode Address File (PAF). PAF is the primary reference for all address data in the UK and contains over 1.8 million UK postcodes and over 30 million residential and business addresses.   The file is updated 4,000 – 5,000 times a day adding new addresses and making changes to existing addresses such as postcode changes.

Our service improves address quality in a number of ways:


Address elements e.g. postcode changes


Mispellings within address elements


Missing address elements e.g. missing town


Address Format

We utilise our own software developed over our many years of trading to enable the highest accurate match rates possible. On completion of our process, we return the data with match levels appended to allow you to assess the quality of your records and identify which records are suitable for mailing and highlight where additional information needs to be collected from your customer to complete the address.  We provide a range of output options to ensure that the enhanced data is compatible with your systems.
