Answers to Questions
How to encrypt a French Postal Barcode?
The French postal barcode (by LaPoste) uses bars and dots (or space), which are read from right to left. It encodes the numbers for the Postal/ZIP code or code Cedex (routing code) and (sometimes) the street number (distribution code). It is located, on most automated mails, usually at the opposite of the stamp.
The code is a substitution using this table :
| 0 | ..|||| |
| 1 | .|.||| |
| 2 | .||.|| |
| 3 | .|||.| |
| 4 | |..||| |
| 5 | |.|.|| |
| 6 | |.||.| |
| 7 | ||..|| |
| 8 | ||.|.| |
| 9 | |||..| |
Example: 75001 is coded .|.||| ..|||| ..|||| |.|.|| ||..||
