Players can receive Coin Codes (also known as Toy Codes) by purchasing Club Penguin merchandise such as extra Card Jitsu packs or books. The codes are printed on plastic coins, or on a card. When players log in to Club Penguin they can click the icon in the upper right hand corner of the screen that says "Unlock Items Online" and there will be a place to enter your code.
Another type of code are book codes. They only require knowledge of the book players have bought because Club Penguin will ask them a question they will know only if they have a book themselves. See also Book (Item).
When you enter a code successfully you will either receive a book item that will be added to your Inventory along with some Coins or you will be allowed to select up to two items from the Treasure Book. The code you receive from when you buy the Club Penguin: Elite Penguin Force Herbert's Revenge will also allow you to use the Puffle Whistle if you're a member.
