is everywhere today.
The International Article Number (also known as European Article Number or EAN) is a barcode symbology used in retail business to specify the manufacturer and model of a product. EAN-13 and its variation EAN-8, is the most widely used EAN today.
A 2-digit country code plus a 5-digit manufacturer code, plus a 5-digit product code, plus a check digit, make up an EAN13 barcode.
When the leading 2-digit country code is 45 or 49, this barcode is a Japanese Article Number (JAN). Smaller product packages use the 8-digit EAN8 barcode.
