Hey, they are codes located on the inside packages of diapers and wipes. You can sign up for either account for free. I believe if you sign up for Pampers you get 100 points and for HUGGIES I think you may get 25 or 50 points but I could be wrong on the HUGGIES. Pampers puts out a lot of codes online. I get mine from coupon sites. You can then redeem the points for a multitude of things to include gift cards, toys, cups, etc. Let me know if you have anymore questions...id be happy to answer:-)
