A Universal Product Code (UPC) is a standardized barcode used to identify and track retail products. Consisting of a series of black and white bars and a 12-digit number, a UPC is scanned at points of sale to retrieve product information such as price, inventory status, and more. UPCs are essential for efficient product identification and tracking during the assembly, kitting, and packaging processes. UPCs help ensure accuracy in labeling, streamline inventory management, and facilitate seamless product distribution across retail and supply chains.
