Who is responsible for maintaining inventory control of mail?

The responsibility for maintaining inventory control of mail falls to the Mail Control Activity (MCA). The MCA is specifically designed to handle the oversight and management of mail within an organization, ensuring that all incoming and outgoing mail is accurately tracked. This includes not only keeping detailed records of mail items but also managing the logistics surrounding the movement of mail, which is essential for maintaining a secure and efficient mail system.

On the other hand, the Military Post Office (MPO), Aerial Mail Terminal (AMT), and Official Mail Center (OMC) have distinct roles in the mail handling process but do not primarily focus on inventory control. The MPO facilitates mail services for military personnel, the AMT specializes in the transport of mail by air, and the OMC primarily deals with official government correspondence. While all these entities contribute to the overall mail system, it is the MCA that specifically ensures meticulous inventory control and tracking of mail items.
