What boxes have Kellogg's Family Rewards codes inside? -

I have checked 6 of my Kellogg boxes for codes and not 1 is in them. I have 4 boxes of Nutri Grain and 2 boxes of Special K Bars Blueberry and Strawberry. Is there a specific place the codes are at? I feel jipped out of points because I was looking forward to these. HELP!
