Abstract
A self-monitoring mail delivery system wherein mail is tracked as it passes through multiple delivery stages. A schedule is created of expected arrival times at each stage. Should a mail piece not arrive on time, the system is alerted to initiate a search for the late or missing mail piece, or to take other corrective action, such as expediting delivery of late pieces. A data center monitors the operations and provides management information to help enhance deliveries.
