An advance copy of the Federal Register notice proposing the use of Intelligent Mail barcodes on automation mailings of letters and flats is now available on Postal Explorer at pe.usps.com. This notice includes revised mailing standards for the use of Intelligent Mail barcodes effective May 2009 concurrent with the date that we implement the mailing services price change.

The comment period will extend 30 days from the date the notice appears in the Federal Register. We encourage mailers to review and comment on our proposal as soon as possible. Mailers may submit additional comments any time within the comment period.
