Please join the U.S. Postal Service for a free, educational webinar on Undeliverable as Addressed (UAA) mail processes.  This session will provide a detailed look at the various equipment and processes utilized by the U.S. Postal Service to detect and process UAA mail.  These vary based on shape (letter vs flat / parcel), point of entry, point of detection, point of processing, UAA reason (COA vs NIXIE), and, of course, mailer’s Printed Endorsement / STID.

Adam Collinson, Director of Address Intelligence, GrayHair Software, LLC and Earl Johnson, Director Addressing & Retail Technical Services and his team will lead the webinar and will cover the flows of UAA mail throughout the vast postal network.
