Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
To change the phone number on a personal Microsoft account:
- Go to Manage how you sign in to Microsoft: https://account.live.com/names/manage and sign in.
- Under Your info / Account alias, find the list of email addresses and phone numbers associated with the account.
- To add a new number, select Add phone number, follow the prompts, and complete verification.
- (Optional) After adding the new number, select Make primary if this should be the main sign-in/recovery alias.
- To remove the old number, select Remove next to that phone number.
Notes:
- A phone number or email used as the primary alias cannot be removed until another email/phone number is added and set as primary.
- These aliases all share the same account settings, subscriptions, and password.
