What does UPC stand for?

The acronym UPC stands for Universal Product Code. This coding system is utilized primarily in retail and inventory management to uniquely identify products. The UPC is a barcode that encodes data using a series of vertical bars and spaces that can be easily scanned by electronic readers.

The use of the Universal Product Code simplifies various processes, such as tracking inventory, facilitating sales transactions at the checkout, and managing product returns. The system is especially important in supply chains, as it allows for accurate and efficient inventory management by enabling retailers and suppliers to quickly and reliably identify products.
