Everyone has to buy the book - or you can send a self-addressed, stamped envelope to the address given in the "Help" section of the website (www.the39clues.com). They will send you the cards for Book 1.
Agent card codes are free, however, and you can create your own agent card, and share your agent card codes with your friends.
For starters, you can add my agent card code "P24R66XMXP", and don't forget to share your own.

In the 39 clues what is the code for card 67?
In the 39 Clues series, the code book is hidden in various locations throughout the series. It is a key part of the Cahill family's quest for power and includes important clues to help unlock the ultimate secret. Each book in the series reveals new clues leading to the code book's location.
It does not have a code it can be obtained when you enter medusa plot book card codes.
on the bottom of a card there is a code, you have to type that code in, and my codes for book one is 22mwk77cx2
The only card that has a reusable code is the Surveillance Camera card (card #1) that comes with The 39 Clues Book 1: The Maze of Bones. Otherwise, you can not use a card code that someone else has already used.
I'm not sure... but heres a code for a 39 Clues card code: P2C2RD4PXP
