EAN (8, 13)
This symbology is reserved for the European Article Numbering (EAN). EAN 8 is used for marking small articles with restricted space. It encodes a unique article number. This number is maintained by EAN and encodes manufacturer and product.
The check digit is calculated automatically if not specified in the input data (that is when only 7 digits are used for creating the code).
EAN-13 is used world-wide for marking retail goods. The symbol encodes 13 characters: the first two or three are a country code which identify the country in which the manufacturer is registered (not necessarily where the product is actually made). The country code is followed by 9 or 10 data digits (depending on the length of the country code) and a single digit checksum. 2-digit and 5-digit supplemental barcodes may be added for a total of 14 or 17 data digits.
Valid characters: "0".."9"
