MAILING SERVICES — GIVING POSTAGE ITS DUE

Compared to the 11-digit numeric POSTNET code most commonly used today, the four-state barcode is said to have the potential to encode three times as much information. As a result, a key benefit of the technology is eliminating the need to put multiple types of barcodes on a single mail piece. This will enable the USPS to offer users better tracking of First Class and Standard mail and make it easier to request special services, such as address correction and confirmation of delivery.
