PLANET (Postal Alpha Numeric Encoding Technique) was used for
the U.S. Postal Service. This US Postal Office uses a combination of
the POSTNET code and PLANET code to track customer’s piece of
mail.
Encoding
PLANET barcodes encodes the data in half- and full-height bars. And
the barcode always starts and ends with a full bar (often called a
guard rail) and each individual digit is represented by a set of
five bars using a two-out-of-five code. In PLANET, the two-of-five
are the short bars.
Check Sum
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 4012345678901 is 0 since
4+0+1+2+3+4+5+6+7+8+9+1=50 which adds check digit 0 result a sum
50.
