NCOA Update


Almost 20,000 UK residents move house every day.

The National Change Of Address (NCOA) file provides details of more than 20 million address changes dating back to 1993. Using information from Royal Mail’s Redirection Service, the NCOA receives up to 100,000 records every month and contains old and new addresses for each registrant.

The NCOA Update service identifies records for which a new address is available and optionally overwrites existing details or appends the revised address in a separate field. The service can also be used to track multiple address changes, following a chain of moves over a period of time.

In addition to enabling companies to keep in touch with valuable customers, even after they move, the NCOA Update file helps to improve campaign ROI. Enhanced address accuracy reduces wasted resource and budget, improving mailing efficiency and avoiding damage to the brand caused by poorly targeted messages.
