Planet barcode symbology is also known as USPS PLANET Barcode. PLANET bar Code is 12- or 14- digit barcode, a two-track barcode similar in structure to the POSTNET Code address barcode that is used in mail processing equipment to sort the mail. PLANET barcodes is one of the most widely used linear barcode symbology that consists of series of long and short bars.
PLANET Code digit symbology is inverse of POSTNET code digit symbology. In each PLANET Code digit uses combination of three tall and two short bars whereas the POSTNET code digit contains the combination of two tall and three short bars. PLANET Codes must begin and end with one long "framing bar".
Structure of a PLANET barcode:
PLANET barcode starts with long bar (frame bar) and ends with a frame bar. Between these two frame bars are the encoded address information followed by a check digit. Each code character is made up five bars, either long or short.
Planet, also known as USPS PLANET Barcode, USPS Confirm Service Barcode, is a linear barcode symbology adopted by United States Postal Service for tracking purpose when mail is processed on automated mail processing equipment.
All planet codes include a check-sum digit or correction character. This digit must always be the single-digit number (i.e., 0–9) which added to the sum of the other digits in the barcode so that whole number becomes multiple of 10.
Depending upon the type of confirmation mail, mailers should choose the appropriate PLANET Code formats:
- Destination Confirm to track outgoing mails. PLANET Codes can be used to identify mail sent to customers.
- Origin Confirm to track incoming mails. PLANET Codes can be used to identify reply mail that customers send back.
