How do I change the phone number in my profile?

Question

I was going thru my profile information and noticed the phone number listed is my personal number, not my company phone. How do I change the phone number in my profile?

Hi @Hickman, Brian (IN HV O NKN OPS HV2-1), 

Thank you very much for reaching out regarding the phone number shown in your profile. I appreciate your patience and the details you provided. 

For Microsoft 365 work accounts, the profile “Work phone” is typically managed by your organization and may appear greyed out or locked. In other words, most users can’t change that field themselves; it’s controlled by IT through the Microsoft 365 admin tools.

Therefore, to update the profile phone number that appears in your directory (the one others see), please contact your organization’s IT administrator and ask them to update your contact info in Microsoft 365 Admin Center (Active users > Contact information) or in Microsoft Entra admin center (Users > Properties/Contact info). Changes made there will sync back to your profile. 

Additionally, while the profile phone number itself is usually locked, you can still update your Multi‑Factor Authentication (MFA) phone number on your own (as long as your organization allows self‑service). This ensures your sign‑in continues to work correctly with your new company phone. If your personal number is currently being used for 2‑step verification, please follow the steps below: 

• Go to Security info > Add sign‑in method by visiting mysignins.microsoft.com/security‑info and signing in with your work account. 
• 
• Add your company phone as a new verification method and test that you can receive the code. 
• Once everything is working, you can remove your personal number to avoid any future sign‑in issues. You’re able to update MFA even if the profile contact fields are locked.

Answer 2

To change the phone number in the profile that is tied to a Microsoft account used with Microsoft 365 for business, update the phone number on the Microsoft account itself.

Follow these steps:

1. Go to Manage how you sign in to Microsoft: https://account.live.com/names/Manage and sign in with the work account.
2. Under the account aliases, select Add phone number.
3. Enter the company phone number and complete the verification process.
4. After verification, select Make primary if that number should be the main contact, and then remove the old personal number if desired.
5. Sign out of Microsoft 365 apps and sign back in so the updated phone number is reflected across services that use the Microsoft account profile.

Note: A primary alias cannot be removed until another email address or phone number exists on the account.
