A Universal Product Code (UPC) is a standardized barcode symbology used for tracking trade items in stores. It consists of a 12-digit numeric code that uniquely identifies a product. The UPC is widely used in the retail industry for scanning at the point of sale, making it easier to track inventory, manage pricing, and streamline checkout processes. The first six to ten digits represent the manufacturer or company prefix, and the remaining digits identify the specific product. The final digit is a check digit used for error detection. UPCs help ensure consistency and accuracy in product identification, improve efficiency in supply chain management, and enhance the overall shopping experience for customers.
