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 |
|---|---|---|
| 0 | 0001101 | 0100111 |
| 1 | 0011001 | 0110011 |
| 2 | 0010011 | 0011011 |
| 3 | 0111101 | 0100001 |
| 4 | 0100011 | 0011101 |
| 5 | 0110001 | 0111001 |
| 6 | 0101111 | 0000101 |
| 7 | 0111011 | 0010001 |
| 8 | 0110111 | 0001001 |
| 9 | 0001011 | 0010111 |
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.
| Checksum | Structure |
|---|---|
| 0 | GGLLL |
| 1 | GLGLL |
| 2 | GLLGL |
| 3 | GLLLG |
| 4 | LGGLL |
| 5 | LLGGL |
| 6 | LLLGG |
| 7 | LGLGL |
| 8 | LGLLG |
| 9 | LLGLG |
| Start | 5 (G) | Separator | 2 (L) | Separator | 4 (G) | Separator | 9 (L) | Separator | 5 (L) |
