Universal Product Code. The Universal Product Code (UPC) is a barcode symbology that is widely used in the United States, Canada, United Kingdom, Australia, New Zealand, in European and other countries for tracking trade items in stores. UPC (technically refers to UPC-A) consists of 12 numeric digits, that are uniquely assigned to each trade item.
The NRF Standard Color and Size Codes are not part of the UPC. A UPC is a 12-digit code that includes the 6-to-10-digit vendor id number assigned by GS1, the 3-to-5-digit product id assigned by the manufacturer, and a final check digit.
