I frequently post free Kellogg's Family Rewards codes whenever they're released, but it's hard to track which codes are available, which are dead, and which I missed. So in addition to posting them one at a time when they become available, I'll keep this master list updated with all the available codes for anybody out there just joining.
If you haven't signed up for Kellogg's Family Rewards, now's the time. In addition to dozens of free codes they offer, you can earn points by entering codes found on most Kellogg's boxes, included all the ones below. The points can then be redeemed for exclusive high-value Kellogg's coupons and even some rewards like magazine subscriptions or toys.
So what the heck are you waiting for? Sign up!

If any of the Kellogg's Family Rewards codes above have expired or if you know of one I missed, please let me know in the comments!
