Answers to Questions (FAQ)

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 .|.||| ..|||| ..|||| |.|.|| ||..||

How to decrypt a French Postal Barcode?

To decode, substitute the vertical bars by the corresponding numbers and read from right to left.

Example: .|||.| .||.|| .|.||| is read 123

How to recognize a French Postal Barcode?

The message consists of sticks and dots (or spaces) by groups of 6: 4 lines and 2 dots, for a french postal code it is at least 30 chars in total.

Any reference to the postman's work, the sorting of mail or the emails is a clue.
