USPS® has revised procedures for Qualified Business Reply Mail™ (QBRM™) customers transitioning to the Intelligent Mail® barcode (IMb™). Unless other aspects of their mailpiece design change, mailers are not required to submit samples or reapply for approval in the QBRM program when transitioning to the IMb by replacing the POSTNET™ barcode with the IMb on existing approved QBRM letters and postcards.
