Definition of delivery point bar code (DPB)

11-digit, 62-bar, machine readable bar code representing a nine-digit ZIP code plus two additional digits, used to address mail. The actual delivery point is represented by the last two digits, which indicate the last two numbers of a residential address, a P.O. box, rural route, or highway contract route. Substantial postal discounts are available to direct-mail marketers who print a DPB on their mail. The DPB enables the U.S. Postal Service to use high-speed scanners to sort mail down to the specific destination point so that it is in the proper sequence for the mail carrier without any manual sorting. The DPB may be printed in the address area or lower right corner of the envelope. If not preprinted by the mailer, the USPS will use high-speed document scanner/ printers to read the address and apply a DPB. bulk mailers who apply the bar code themselves have greater latitude with regard to the selection of envelope colors and print styles without giving up postal discounts.
