Symbologies

POSTNET Status

POSTNET is used by the United States Postal Service to direct mail. The ZIP Code or

ZIP+4 Code is encoded in the symbol. Data is encoded in half-height and full-height

bars, making POSTNET a “2-state” symbology. The delivery point (usually the last two digits

of the address or post office box number) is also typically encoded in POSTNET symbols.

If U.S. Postal and POSTNET Status are both enabled, the imager will decode POSTNET

symbols.

PLANET Status

PLANET (Postal Alphanumeric Encoding Technique) is a symbology used by the

United States Postal Service to track and identify items during delivery. Each PLANET

symbol is either 12 or 14 digits long, and encodes

data in half-height and full-height bars,

making PLANET a “2-state” symbology. The symbol always starts and ends with a full-height

bar, or “guard rail”, and each individual digit is represented by a set of five bars in which

two of the bars are always short.

If U.S. Postal and PLANET Status are both enabled, the imager will decode PLANET

symbols.

USPS4CB Status

USPS4CB, also called Intelligent Mail, is used by the United States Postal Service to sort

and track individual items as well as flats of mail. USPS4CB combines the capabilities of

POSTNET and PLANET, and can encode 31 digits (65 bars). USPS4CB symbols are

slightly longer than POSTNET symbols, and offer additional flexibility in choosing symbol

height and width.

Data is encoded in four types of bars (“states”), each of which is identified by a name and

a value. This type of postal symbol is known as “4-state”. Each bar has a “tracker”, or middle

section, to which an “ascender” (top section) or “descender” (bottom section) may be

added. The 4-state format allows the symbol to contain more information, and makes it

easier to decode. 4-state symbols can also be printed easily in a variety of media, including

dot matrix, inkjet, and laser.

If U.S. Postal and USPS4CB Status are both enabled, the imager will decode USPS4CB

symbols.
