EAN 13 Intro
The International Article Number (EAN) (also known as European Article Number, which technically refers to EAN-13) is a 13-digit barcode symbology, which is a superset of the original 12-digit Universal Product Code (UPC) (also known as UPC-A), developed in 1970 by George J. Laurer. The EAN-13 barcode is used worldwide for marking products often sold at retail point of sale. It encapsulates 2-digit or 3-digit number system (GS1 Prefix (usually GS1 country code)), in contrast with UPC-A's 1-digit number system.
