My elite controller series 2 can't be registered, it says the device serial can't be found....

Hello, Ahbab. Thanks for reaching out! My name is Lucas, and I'm an Independent Advisor and a Microsoft user just like you. I'll be happy to assist you today.

Are you trying to register it on?

Try to register it on Microsoft Edge using a InPrivate window. Or try a different browser also with a InPrivate / Incognito window.

If it still does not work, please let me know.

As far as I know you can't register any controller I tried to register my elite controller but the serial number was the wrong length

Hello I found this post as I am also having the same issue, I am looking at the serial number on the back of my official Xbox Elite Series 2 controller and trying to enter it when registering a new device. I have a broken joystick and am trying to look up the warranty or initial repairs but I am getting a "We couldn't verify the serial number. Check the serial number and try again." error message but I am definitely entering the serial number in correctly. So confused on what to do and still need help with repairs on my controller.

You need to contact xbox support to help you set up a repair for elite controllers as you can't simply register them with serial number.

Unfortunately, because i bought the elite controller on its own, i cant seem to register it. When asking where to find the serial number there is no option for the xbox elite series 1. Other people have said unless you bought the package (Which i didn't)
there the serial number option doesn't register the serial number of the controller. the only way to register a xbox elite controller is to by the paddle package and then the serial number is accepted. Personally i don't want to have to buy something just
to be able to see if a warranty is still active.
