The document provides information about Intelligent Mail Barcodes (IMb), including what they are, how they will help mailers, and the steps needed to transition from POSTNET to IMb. IMb will provide end-to-end visibility of mail and enable automated discounts. Mailers must obtain a Mailer ID, apply for IMb, and update return address panels with the new barcode. While the USPS initially planned for mandatory conversion in 2011, automation discounts for POSTNET will continue beyond that date.
