My elite controller series 2 can't be registered

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.

Hi Colby! I'm more than happy to help you!

I'm sorry you are experiencing this with your Xbox Elite series 2 controller. No worries, let me help you sort this out.

Since you have exhausted all the troubleshooting steps and the controller serial number still unable to be registered on your account, nothing to worry! You can reach out to Microsoft Xbox Support for further assistance as they have the tools and resources to properly check your device and possibly create the warranty replacement order for you.

Before you contact them make sure to prepare the screenshots of your controller serial number, the controller itself, and possibly the proof of purchase/receipt. You may contact them using the link below:

Thank you for your kindness and understanding! Please feel free to let me know if you need anything else.

Best Regards,

I have exactly the same issue with the new Series 2 controllers. I ordered the Electronic Volt version, but had to refund it because of the mentioned problem. Then I ordered the Xbox Elite Series 2 controller, thinking a 150€ controller sure can't have these problems, but I was wrong.

So here I am, stuck my old Elite Series 1 controller that still works after several years, but starts to show wear, and I can't upgrade to Series 2 without winning the series-2-build-quality-lottery.

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

I had purchased the Xbox Elite Series 2 Controller, sorry I can't be of more help.
