Postal regulations require you to submit US Postal Service Form 3553 with each mailing claimed at an automation-based rate to demonstrate that you have used CASS-certified software. The Form 3553 shows, among other things, the number of addresses in your list file and the number of addresses that have a valid ZIP+4.
Because numerous postal regulations that determine the eligibility of your mailing for the automation-based rates, we strongly encourage you to work with your postal representative to make sure that your mailing meets all requirements.
