There are no cheat code in any game in the 39 clues.
There is nothing called a code book. The 39 clues cards have codes by which you unlock cards. If you mean Agent Card Code then you can get your agent card code in the agent card option in my cards. My agent card code is P2FHHNDHXP
There is not going to be a 12th 39 Clues book, but there is going to be a new 39 Clues series. The first book in the new series is called The Medusa Plot by Gordon Korman.
this is a new card code from the book titled vespers rising the card code will give you 6 cards to unlock mission 11 the card code is KCXJTCK3T3
All of them expired, no "really new cheat code". The only code to get is the code you obtain when you buy a wizard101 gift card.
