EAN/JAN-13 Barcode

EAN or European Article Numbering system (also called JAN in Japan) is a European version of UPC.

The difference between EAN-13 and UPC-A is that EAN-13 encodes a 13th digit into the parity pattern of the left six digits of a UPC-A symbol. This 13th digit, combined with the 12th digit, usually represent a country code.
