POSTNET Barcode Discontinuation Proposed

On March 2, 2012 the POSTNET™ Barcode Discontinuation proposed rule was posted on the Federal Register website.

The proposed rule includes the basis for discontinuing use of POSTNET™ barcodes and allowing only Intelligent Mail® barcodes (IMb™) for automation price eligibility by January 2013. The Postal Service™ understands that many mailers currently use POSTNET barcodes and we are committed to providing information to and working with individual mailers and software providers to ensure that the use of an Intelligent Mail barcode is achievable for all mailing customers.
