The Universal Product Code (UPC) is a barcode symbology (i.e., a specific type of barcode) that is widely used in the United States, Canada, the United Kingdom, Australia, New Zealand, and in other countries for tracking trade items in stores. Any product with an existing UPC does not have to be re-marked with an EAN. 2  In America the EAN adds 40% more codes, mainly by adding '10 through 13' to the '00 through 09' (0 through 9 in UPC) already in use. 3  This is a powerful incentive to phase out the UPC.
