USPS and 4-State Barcodes in LEADTOOLS
Show in webframe
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 different widths that most linear 1D barcodes employ. 2-state barcodes are able to encode the digits 0-9 and are effectively used for zip codes, routing and tracking numbers while 4-state barcodes can encode alphanumeric characters and can encode the entire address information.
Sample Barcode:
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 may be printed upon an envelope and be used to facilitate faster sorting of mail. These symbols are printed upon flat pieces of mail such as magazines and envelopes.

Sample Barcode:
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. PLANET is used by the United States Postal Service to identify and track mail during delivery.
