Ean 2

ISSN with an EAN-2 addon representing issue number 5.

The EAN-2 is a supplement to the EAN-13 and UPC-A barcodes. It is often used on magazines and periodicals to indicate an issue number.

Encoding

The encoding of EAN-2 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-2 always begins with "01011". Also, the R-Code is not used.

Encoding of the digits
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 value of the two digit to be encoded. The two digits treated as a single two-digit number is reduced modulo 4 and used to find the parity pattern to be used. The parity pattern repeats every 4 values.
