you mean club Nintendo? the pin # they give you is on the pamphlet that advertises about joining club Nintendo included with the game. you might need your serial system number before joining; the wii's number is at the bottom, the 3ds at the back, but I'm not sure of the wiiu, ds, or 3ds xl. after December 2012, Nintendo cancelled Nintendo power magazine and has officially moved on to Club Nintendo permanently to "compete" with other gaming websites that reveal secrets of upcoming video games. just answer their surveys to win imaginary super Mario coins and trade them for actual products from Nintendo. These products are usually sold out, rare, or expensive to buy at selected electronic stores. I once saw a Mario plush doll that was made by Nintendo at best buy and it was sold for about 40 bucks, and it was only 1 copy left! hope this helps! I also believe you can only join until 2015, so you're still good to apply.
