NCOA® Update

The NCOA® (National Change Of Address) Update File is built exclusively from data sourced from the Royal Mail® Redirection Service, and can be used to help you stay in contact or re-connect with your customers who have moved.

Moving house is one of the most stressful things we can do , so it is no surprise that people often forget to update their details with all the companies they do business with. The file contains approximately 23 million records (November 2014), dating back to 1995, and continues to grow at the rate of around 100,000 records per month.

The NCOA® Update File is not available to buy direct. Due to the sensitive nature of redirection data and to comply with the Data Protection Acts of 1984 and 1998

The NCOA® Update File is held only by specially recruited data management bureaux such as Dynamic Data Services Limited.

If you require your forwarding details to be removed from the main Royal Mail NCOA® file then please contact Royal Mail directly by e-mail at
