Planet Overview

This part talks about the Planet barcode. The Postal Alpha Numeric Encoding Technique (Planet) barcode, is a 12-digit or 14-digit long numeric symbology mainly used by the United States Postal Service to identify and track inbound and outbound letter mail & packages during delivery.
