Here is a list of every working Animal Jam code - for free! If you do not know how to use codes, scroll down for a guide! (We cannot legally give out Membership codes - sorry!)
Codes that give gems:
explorer - 100
NGKAJ17 - 500 gems
Total: 600 gems
AJBDAY6 - 6th Birthday Cake
Unfortunately, AJHQ has removed most of the older codes this year, so the list has become a lot shorter. Hopefully they'll update the list soon!
If you find that one of these codes is expired, or you know of a new code, please comment!
To enter a code, first go to the Animal Jam Homepage. After you type in your username and password, click the check box next to "I Have a Code to Enter!". Then type in the code you want to use! Codes can only be used once.
When you enter your code, username and password, click "PLAY". After you have chosen a server and loaded the game, you should get a pop-up. Click the present...
And you should get your free gift!
If you get a pop up like this when you click "PLAY", you have typed the code in wrong. Try again! If it still doesn't work, comment here and tell us. The code may be outdated.
