POSTNET Barcode Discontinuation Correction

On Wednesday, June 6, a revision to the POSTNET™ Barcode Discontinuation final rule was posted on the Federal Register website and it will be posted soon on the Postal Explorer^®website under Federal Register Notices.

This document corrects the May 3 final rule that discontinued price eligibility based on the use of POSTNET™ barcodes on all types of mail. The correction merely adds Domestic Mail Manual (DMM^®) revisions regarding Periodicals automation letters and flats that were inadvertently omitted from the original final rule. The effective date is January 28, 2013.
