This is a rather complicated question! Let me try to reduce it down to the basic elements. . .

First, the UPC code on a product is an 11 digit number followed by a mathematically calculated check digit. (If you are curious as to how that calculation is done, please visit our check digit page at upccode.net/upc_check.html)

The coupon code for any given product can take several forms. The easiest form is that of a 12-digit code at the front, consisting of:
- UPC prefix 5 indicating that it is a coupon,
- followed by digits 2 through 6 of the UPC number of the product for which the coupon is intended,
- followed by a 3-digit family code selected by the manufacturer or the retailer for whom it’s intended,
- followed by a 2-digit value code from the coupon value code table indicating the % off or $ off or whatever value of the coupon
- followed by the new mathematically calculated check digit

Most coupons then feature a second barcode, called the coupon extended code. This extended code can take several forms. The simplest one includes the applicationa identifier (8100) plus a 5-digit offer code selected by the manufacturer. This code is designed to allow the manufacturer to track each coupon offer.

There are versions of the extended code that add an expiration date and others that add household IDs.

This is a very general overview. If you need additional details, please contact us at UPCcode.net.
