Barcode – EAN-13
EAN is designed by the International Article Numbering Association (EAN – now GS1 in Europe). It is an extension to UPC-A to include the country information.
The only difference between UPC-A and EAN-13 is that the number system in UPC-A is a single digit from 0 through 9 whereas an EAN-13 number system consists of two digits ranging form 00 to 99. EAN-13 encodes 12 digits of numeric data along with a trailing check digit, for a total of 13 digits of barcode.
