I have Changed my phone Number but still all confirmation messages comes on my old phone number

Hello EzaX,

Thanks for posting on the Xbox forums. We understand that you would like to update the phone number that receives your account's messages. We recommend going to

the security section of your account and updating the phone number. You can remove the old phone number once you have updated your security information. Also, we suggest adding your new phone number to
the account alias section. You can access the account alias section of your account through the section that says, "Manage how you sign in to Microsoft." Be sure to let us know
the results EzaX!

i did, in the security settings i now have my good number phone but when i go on the xbox they still propose me my old number phone ( i restarted my xbox in case of but same thing happen), maybe i have to change my phone number on a different site or something
?

Hi Joseph! I'm Rostom, an Independent Advisor. I will be glad to help you here. No worries, we will do our best now to get this sorted out.

I just want to confirm, are you still able to play or access your games from your console?

Has your query been resolved ?

Hi. My name is Brilliant and I am happy to assist you today.

To remove / add / update a phone number on your Microsoft account:
1. Go to "Manage how you sign in to Microsoft" and sign in to your account: https://account.live.com/names/Manage

2. Select "Add phone number" and follow through the process of verifying your contact details and adding it to your account.

3. You can make the new contact the primary alias by selecting "Make primary".

4. You’ll then have the option to remove the old email address or phone number from your account.

Hope this helps resolve your query. Have a great day.
