Where do I register my Wii serial code in Club Nintendo? - wii serial lookup

I went into the series in the "Enter games purchased" NIP / section number, but when I was in my Wii code number, which says it is invalid! I triple checked the numbers and this does not work, I think, I suppose, go somewhere else.

Oh, and I bought the Wii brand new! On one side of the car, because they are not sold on the shelves!
