National Change Of Address

What is the NCOA?

NCOA: National change of address is a dataset available from Experian Data Quality that is sourced from the Royal Mail’s redirection service. There are over 21 million records in the NCOA® Update file, and it is growing by 1.2 million every year.


Why use the National change of address dataset?

The end user, customer, choses to supply a new address when they move house or business, so that they can continue to receive post. For business this means that they can continue to communicate with customer and reconnect with those lost from a change of address. On average 11% of UK's population move every year, that equals 18,000 a day. Royal Mail state that around 50% of movers take up the NCOA® Update service.
