To change your phone number on Facebook, log in with your email address or phone number and password, then open your account settings and navigate to Accounts Center, then update your contact information. Keeping your phone number current matters because it ensures you receive login alerts and can recover your account if you ever get locked out.
How to change phone number on Facebook
First, log in with your email address or phone number and password. Click the downward-facing arrow in the top-right corner and select Settings & Privacy then Settings. Facebook stores your contact details in the Accounts Center, which is the central hub for managing personal information across Facebook and Instagram. On the General Account Settings page, click Contact on the left-hand side. The exact path to reach your contact info is: Settings and privacy > Settings > Accounts Center > Personal details > Contact info.
Add your new phone number
Once you are inside the Contact info section, follow these steps to add your new number:
- Tap or click Add new contact.
- Choose Add mobile number.
- Enter the new phone number. Facebook may prompt you to re-enter your account password for security verification.
- Complete the verification code prompt that follows. Facebook will send a code via SMS or phone call, and you enter that code to confirm the number.
After the code is accepted, Facebook confirms the addition is complete. This process works the same whether you are using a mobile browser, the Facebook app, or a desktop computer.
Remove your old phone number
Removing your old number is optional but recommended if you no longer have access to it. Inside the same Accounts Center > Personal details > Contact info screen:
- Tap or click the mobile phone number you want to remove.
- Select the remove option that appears.
This step helps keep your account clean and prevents accidental use of an outdated number for login alerts or account recovery.
What to do if the verification code doesn't arrive
If Facebook sends a confirmation code but you do not receive it, first double-check the mobile number you entered. If the number was wrong, use the Update contact info option to correct it. Once the correct number is saved, request a new code. No carrier-specific steps or device-specific workarounds are documented for this issue.
Phone number for two-factor authentication is different
Changing the phone number used for two-factor authentication is a separate process from updating your profile contact info. To change the two-factor authentication number, go to Accounts Center > Password and security > Two-factor authentication. Do not confuse this setting with the contact info section, the two-factor number controls login security, not your visible profile details.
Frequently Asked Questions
Is it necessary to update my phone number on Facebook?
Yes, it is important for security, communication, and account recovery.
Will changing my phone number on Facebook affect my account settings?
No, it will not impact account settings.
Does changing my phone number affect my account settings?
No. Changing your phone number in Contact info only updates how Facebook reaches you for notifications and account recovery. It does not change your password, privacy settings, or any other account preferences.
Can one phone number be linked to multiple Facebook accounts?
No. Each phone number can only be linked to one Facebook account at a time. If you try to add a number already in use on another account, Facebook will prompt you to remove it from the other account first.
What should I do if I cannot access my old phone number and need to log in?
If you are locked out and no longer have access to your old number, use Facebook's account recovery options. You can request a code via your email address or use trusted contacts if you set those up previously. Once back in, immediately add your new number and remove the old one.
Does updating phone number on apps also update it on the website?
Yes. Because the phone number is stored in your Accounts Center, any change you make in the Facebook app, Messenger app, or on the website applies everywhere. Updating your phone number on apps and accounts is handled centrally, so you only need to do it once.
How many phone numbers can I add to my Facebook profile?
You can add multiple numbers through the Add new contact option, and each can be removed individually when no longer needed.
