The UPC number is found underneath the bar code (scanner code) on each package.
The production code is a series of letters or numbers embossed or inkstamped on the packaging. For products sold in bags or pouches, the code is usually located on the back of the package (but may also be on the front or bottom.) For products sold in cartons, the code is on the Product Information Panel on the side or end panels. For products sold in bottles, the code is usually on the cap or back of the bottle.
