EAN-13 is also known as
- European Article Number 13
- EAN-13 Supplement 5/Five-digit Add-On
- EAN-13 Supplement 2/Two-digit Add-On
EAN-13, based upon the UPC-A standard, was implemented by the International Article Numbering Association (EAN) in Europe. EAN-13 is a superset of UPC-A. This means that any software or hardware capable of reading an EAN-13 symbol will automatically be able to read an UPC-A symbol. The only difference between EAN-13 and UPC-A is that the number system code in UPC-A is a single digit from 0 through 9 whereas an EAN-13 number system code consists of two digits ranging from 00 through 99, which is essentially a country code.
