USPS and 4 State Barcodes in LEADTOOLS

LEADTOOLS supports several 2-state and 4-state barcode symbologies employed throughout the world by various post mail office systems. These barcodes are comprised of bars of different heights as opposed to the different widths that most linear 1D barcodes employ. The 2-state barcodes are able to encode the digits 0-9 and are effectively used for zip codes, routing, and tracking numbers. The 4-state barcodes can encode alphanumeric characters and can encode the entire address information.

Postal Numeric Encoding Technique (POSTNET)

POSTNET was developed by the United States Postal Service (USPS) to represent the 5- or 9-digit ZIP code, or an 11-digit "Delivery Point Code" of US destination addresses. A POSTNET symbol can be printed upon an envelope and used to facilitate faster sorting of mail.

Post Alpha Numeric Encoding Technique (PLANET)

PLANET is similar to POSTNET in that it uses half and full height bars to encode data, always begins and ends with a full bar, and digits are represented using a two of five code. The major difference between POSTNET and PLANET is that in POSTNET full bars represent "on" bits, while in PLANET full bars represent "off" bits.
