UPC/EAN (Universal Product Code / European Article Numbering) is probably the most widespread barcoding system. EAN codes (8 and 13 digit) are used in all European countries, while UPC ones (8 and 12 digit) are more frequent in the North America. The encoding scheme for both barcode types is the same (12-digit UPC is a subset of 13-digit EAN). These barcodes can carry numeric information only.

The generator supports EAN-13, EAN-8, UPC-A, and UPC-E barcodes, including checksum generation. Type of the generated barcode is deduced from the input data, or specified explicitly as a parameter to the stylesheet.
