Planet - Barcode Type¶

Used by the United States Postal Service until 2009, the PLANET (Postal Alpha Numeric Encoding Technique) barcode was used for encoding routing data on mail items. PLANET uses numerical input data and includes a modulo-10 check digit. While Zint will encode PLANET symbols of any length, standard lengths used by USPS were Planet12 (11 digit input) and Planet14 (13 digit input).
