Address Cleansing Services

Powerful address cleansing which utilises the extensive in-house knowledge, the latest technology and third-party data sources available to ensure date hygiene.

The Royal Mail Postcode Address File (PAF) is the definitive source for personal and business postal addresses in the UK. It contains every delivery point in the UK and is being constantly updated. Can also be used with Multiple Residence and Not Yet Built data to give additional postcodes.


Postcode Address File. 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 nearly 5,000 times a day.



Multiple Residence Data from Royal Mail provides access to self-contained flats, sub-divided houses, apartment blocks, halls of residence, and nursing homes. Lookup and verify over 800,000 additional premises not included in the PAF.


By using Not Yet Built together with Royal Mail Postcode Address File (PAF), businesses can identify and deliver services to the addresses of properties that are at the planning and construction stage. The additional dataset holds more than 500,000 new homes and offices not yet in PAF.
