In The 39 Clues book series, each book contains a set of cards that can be used to unlock online missions and clues. The specific card codes are unique to each book and are typically found on the inside of the book jacket or on a separate card within the book. These codes are essential for participating in the interactive online component of The 39 Clues series.

You only can get the card codes by purchasing the The 39 Clues card pack. Codes can only be used once. If the card code has already been entered in your gallery or another player's gallery, it won't work for your gallery.
You need to play the missions, buy the books, and buy the card packs. Enter the card codes. Then you can gather clues.
