National Change of Address (NCOA)
The National Change of Address database is a dataset of approximately 160 million records consisting of the names and addresses of individuals, families and businesses who have filed a change-of-address with the USPS. When we process your list we will compare your list against the NCOA database and notify you of any records that have moved. We will also be able to provide you with their new address if they have provided it to the USPS. This helps ensure you are only sending mail to the individuals or businesses in your database and allows you to qualify for bulk mail discounted rates.
