what does upc stand for in products
What is a UPC barcode? And how does it work? In short, the UPC is a 12-digit unique code for your product represented by scannable bars. Universal Product Codes (also known as GTIN-12) appear as lines (bars) of varying widths representing the series of numbers commonly shown below the bars. Barcode scanners read the bars and convert them back to the 12-digit UPC number that they represent.
