CASS certification is used when a mailer wants additional discounts for putting bar codes on the mail. Initial savings from first-class machinable mailings come from sorting, not from bar coding. You can receive additional discounts if you utilize CASS Postal Bar Coding. The USPS does not allow you to put bar codes on your mail if you can’t prove that the bar codes are based on accurate 9-digit zip codes. They don’t want to give you a discount and then have to handle the mail by hand due to inaccurate barcoding.

CASS certification is the process of matching your address list to the USPS master list of zip+4 codes. CASS software is tested by the USPS to make sure it can perform a correct match even when there are errors in the address. This process also helps you fix incorrect addresses. The USPS will accept your bar codes as accurate if you show that you recently matched your address list against their master 9-digit zip code list. Software that is approved to do this matching will print a special “CASS report” when it runs your list, showing how many addresses were attempted, how many were matched, when the matching was done, and the date of the master zip code list was used.

How much will you save? Initial savings will come from presorting your mailing. Additional savings are achieved by qualifying for automated rates by utilizing barcoding with your mailing. Barcoding savings range anywhere from 0.3¢ to 2.3¢ per piece. The largest barcoding savings are for mailings that have more than 150 pieces going to the same 5-digit zip code, with smaller savings for mailings that are scattered among many zip codes without 150 pieces to any one zip code.
