Introduction
This US Postal Office uses a combination of two tracking numbers (the
POSTNET code and PLANET
code ) to track customer’s piece of mail. USPS confirm service provides
delivery information about (1) Incoming hard-copy reply mail (Origin
Confirm) and (2) Outbound mail going to customers ( Destination Confirm).
A PLANET symbol have 12 or 14 digits. PLANET code symbology is the
inverse of the POSTNET codes. The encoding is shown in the below table:
Check Digit Calculation
The check digit is based on Mod 10 algorithm. The value of the check
digit is that when added to the sum of other digits in the barcode, results
in a total that is multiple of 10. For example, the check digit for address
code 40123456789 is 1 since 4+0+1+2+3+4+5+6+7+8+9=49 which adds check digit
1 result a sum 50, 5 times of 10.
Structure of a PLANET symbol
The PLANET barcode starts with a 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.
Barcode Locations
PLANET barcode can be anywhere in the address block portion except the
lower right. For more information, visit
