All our coupons print with either a GS1, UPC A, EAN barcodes, or a combination. If you are not seeing any barcode on your coupon please read Why do my coupons print without any barcodes?
The GS1 barcode is intended to make it easier for manufacturer’s to specify exactly what product the coupon used for and more easily enforce it at the register.
However, more manufacturers are choosing to go with only the new GS1 barcode. Please be assured that a coupon with only the GS1 barcode is a valid coupon and should be accepted by your retail store.
