New Nexus Card Activation
New Nexus Cards have been sent to participants in the Nexus Trusted Traveler program. The cards are sent in the mail, without any sort of tracking. You have only 30 days to activate your new Nexus card, or both your new card and your old Nexus card will be deactivated. This is very important! If you do not activate promptly, you may lost your Nexus privileges.
Aside from the way they were mailed without tracking nor advance notice, the biggest issue with the new Nexus Card activation is the web URL for card activation. It is plainly listed in the envelope with the new Nexus card as https://goes-app.cbp.dhs.gov If you try and go to http://goes-app.cbp.dhs.gov it will not come up and there will not be any error message. This is a bug in the governments implementation, but since there is no message you may never know why the web site is not working for you.
Be very careful typing in that extra "s" in the "https" part, or better yet just use this live link:
What You Need to Activate Nexus Cards
In order to activate your Nexus card, you will need the small account and security code numbers written on the back of the card (circled in red in image above). They are VERY SMALL, so check that you can read them properly before attempting to activate using the online form.
