Encoding
The Encoding of EAN-5 characters is very similar to that of the other European Article Numbers. The only difference is that the digits are separated by 01. The EAN-5 always begins with '01011.' Also, the R-Code is not used.| Digit | L-code | G-code |
The structure of the barcode is based on the checksum. In order to compute the checksum, multiply each of the digits by either 3 or 9, alternating each time. Then add them and then do a mod 10. So the checksum for 05415 MN is 1 based on the following calculations:
0*3=0
5*9=45
4*3=12
1*9=9
5*3=15
----------
81 % 10 = 1
Once you have the checksum digit, you can look up the structure in the following table. Note that the checksum digit is not in the final 5 digits, and is not intended to validate the 5 digit data, but rather to validate the reading of the EAN-5 overall.
