The EAN standard functions as a numbering system and a barcode symbology. It aids in identifying specific retail products, manufacturers, as well as packing configurations. Since the Global Trade Item Number (GTIN) standard from the GS1 organization includes the EAN standard, referring to EANs as GTINs is possible. They may also be encoded in other GS1 defined barcode symbologies.
The use of EAN barcodes is common for product identification and billing at retail points of sale. They might also be used for other purposes such as accounting and wholesale ordering.
The 13-digit EAN-13 standard is used most commonly. It comes with a three-digit prefix that represents the registration country or a special product type. When an EAN-13 comes with “0” as a prefix, the following 12 digits are the product’s Universal Product Code (UPC-A). Prefixes of “45” and “49” are indicative of the use of a Japanese Article Number (JAN).
The EAN-13 standard includes four parts.

EAN-8 barcodes are not used as commonly as EAN-13 barcodes. They were introduced for small packages, where using EAN-13 codes is not feasible.
The two-digit EAN-2 standard and five-digit EAN-5 standard provide supplemental barcodes. They are found placed toward the right of an EAN-13 or a Universal Product Code (UPC-A). Their use is common in periodicals and weighed products.
GS1, formerly known as EAN Association, is responsible for developing and maintaining different EAN standards. It has over 110 offices the world over.
EAN-13 was built on the Universal Product Code (UPC-A) standard developed by George J. Laurer in 1970. The European Article Numbering (EAN) Association, an international not-for-profit standards organization, was founded in 1977. Headquartered in Belgium, the association had 12 founding members, all from Europe. They then worked in launching the GS1 identification system to improve efficiency in their supply chain systems.
In 1990, EAN signed a global international agreement with the Uniform Code Council (UCC). Its presence then expanded to 45 countries. Together, they launched the Auto-ID Centre in 1999 and the Global Data Synchronization Network (GDSN) in 2004. The organization increased its presence to more than 90 countries by 2005, by which point it started using the name GS1 globally.
