Effective July 28, 2013, the Postal Service™ will revise the Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM®) 302.5.0 to remove obsolete language that prohibits 5-digit or 9-digit routing barcodes on automation flats. That restriction was implemented when the qualifying barcode was a POSTNET barcode. Now that all automation flats must have an Intelligent Mail barcode (IMb), and in recognition of the practice of upgrading the quality of barcodes on flats, a non-qualifying 5-digit or 9-digit barcode will be allowed on an automation flat as long as the qualifying barcode also is on the flat in a location as allowed by DMM 302.5.1. As a reminder, DMM 302.5.1 will remain as is, and mailers may use the new option immediately.
