Many of our Landsharkz-designed geocoins have the activation code: "SHARKZ". If this does not work, you can find the activation code to any trackable on Geocaching.com
On the Geocaching.com “Retrieve Activation Code” page, simply enter the tracking number found on your coin (don’t forget to fill in the re-captcha numbers in the box above) and it will give you your activation code. If you’re entering your tracking code on Geocaching.com and it’s not coming up, double check to see if any zeros have been mistaken as O’s, etc. Contact Landsharkz if you are having any additional problems.
From here, go to the “Find Trackables” page on Geocaching.com (under the “Play” tab). Make sure you are logged in so you can properly activate your trackable! In the middle of the page, there is an “Activate Trackable” box, where you enter your tracking number. Once you click the “Activate” button, you will be prompted to enter the Activation code you just found.
