What is the Universal Product Code (UPC) adopted for?

UPC stands for Universal Product Code and is a standard product-coding barcode widely used in retail. The UPC was first adopted for the grocery industry and became the most widely used product coding standard, printed on most consumer products to enable product identification, point-of-sale transactions, inventory control, and stock tracking. Modern packaging and retail systems rely on UPC and related symbologies (e.g., EAN) to automate scanning and data capture, making the UPC specifically a barcode standard rather than a building code or a food adulteration law.
