How many Ancillary Service Endorsements (ASE) are there?

The correct number of Ancillary Service Endorsements (ASE) is six. Each endorsement serves a specific purpose in the routing and delivery of mail services, providing options for handling and delivery preferences. These endorsements are designed to give senders the ability to communicate specific instructions regarding their mail, such as whether the mail should be returned if not deliverable as addressed, whether the item should be forwarded to a new address, or if it should be held for pickup. Understanding the various ASEs is essential for optimizing the handling and efficiency of mail services, ensuring proper delivery outcomes based on the sender's needs.
