A pin number is a code on your membership card that you have to activate.Sometimes you can't find the pin number because you didn't scratch a GREY thing(not you).
You find a pin and walk over it.
Once you find a pin in Club Penguin, you have to walk up to it. Then it will be added to your inventory. You can then put it on your player card by clicking it in your inventory.
Every single pin on club penguin is used for putting on the player card at the top left corner.
