国际商品编码（International Article Number），即欧洲商品编码（European Article Number, EAN），是原来只是欧洲范围内的、而现在已是全球范围内产品交易的商品代码。为了适应读码器辨认的需要，这些代码又被做成大家熟知的条形码。

另外，日本于1978年在EAN的基础上开发出「JAN码」（JANコード，Japanese Article Number）。

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.
