The Universal Product Code (UPC) has been successfully employed in the retail industry in the United States and Canada since 1973. UPC is a coding system as well as a barcode; it is designed to uniquely identify a product and its manufacturer.
The UPC Version A code is a 12 digit code, the first 6 digits represent the manufacturer of the labeled item, the next 5 digits are a unique product identifier and the 12th digit is a check character, based on the previous 11 digits of data.
EAN is very similar in structure and algorithm to its American counterpart UPC, some readers and scanners effectively treat them as being the same.
