Understanding Postal

Next March, the USPS will implement new delivery address placement and format requirements for flats, the size of mail that most catalogs are classified under.

The requirements will apply to ALL catalogs and not just those destined for postal facilities that will have the new Flats Sequencing System machines that the USPS will begin deploying this fall. And this is regardless of how flats are presorted, whether they’re barcoded or where they entered the mailstream.
