Background
The U.S. Postal Service processes approximately 98,000 address changes per day. The National Change of Address (NCOA) is the system of record for all change of address requests and stores approximately 160 million change of address records. The Postal Service processed nearly 36 million address changes in 2021, with over 20 million submitted online through the Moversguide application.
 
What We Did
Our objective was to evaluate the effectiveness of the Postal Service’s controls over the security and availability of the NCOA and Moversguide applications.
