The Mailers Technical Advisory Committee (MTAC) Work Group (WG) 145, established to "Promote Significant Usage of 24-Digit Intelligent Mail® Tray Labels," requests your assistance-please complete a short survey that will help us collect data on the use of 24-digit tray and sack labels. The survey will close on October 21, so please complete it and submit it as soon as possible. As background, Intelligent Mail (IM) tray labels are the Postal Service's approved method for providing a unique identifier for trays and sacks and for encoding routing, content, origin, and mailer information. Without a unique identifier, the potential benefits of in-transit visibility, manifest reconciliation, and automated mail acceptance are greatly diminished. Requirements for the 24-Digit Intelligent Mail Tray Label format are in Domestic Mail Manual (DMM) section 708.6.5.3. If you have any questions or comments, please direct them to Postal Service work group leader Himesh Patel by phone 703-280-7498 or by email himesh.a.patel@usps.gov or to Industry work group leader Paula Stoskopf by phone 856-246-8842 or by email pstoskopf@grayhairsoftware.com.
