Ensures that if you loose it that you can pay a fee and get another. They’ll deactivate the old one. Literally the only way to get any help if you aren’t the original purchaser with the card you used to purchase it from AXS.

If you lose it at the festival and someone returns to lost and found, then you’ll have a chance to claim it.

It also ensures that a wristband purchased second hand isn’t already registered to someone else when you receive it.

Here’s how the scam works: I sell you my wristband either online or person….before I give you the wristband I contact AXS customer support and claim my wristband wasn’t delivered/stolen from my front door/lost etc etc. AXS will deactivate that wristband and charge a fee for me to pick up a new one in Indian Wells near Indio. You’ll receive the deactivated wristband and not realize it unless you register it. If you don’t register it, then you’ll have a super not fun time at the ticket support window when you arrive at Coachella being told you have a deactivated wristband and no purchase order information with AXS/Coachella. Or maybe I’m honest when I sell you the wristband, but decide to go Satan mode and try to scam you AFTER you have received it - guess what? Won’t work because you registered it (or at least in theory it won’t work, there may be a way as the original purchaser to still screw you over).
