Preparing to Update Your Contact Details
Before you change phone number in Facebook account, make sure you can access your email and current phone number. If your old number is no longer active, you may need to use an alternate recovery method or customer support. Being prepared reduces delays and keeps your account safe.
Check Device and Network
Use a trusted phone or computer with a stable internet connection. Avoid public or shared devices, and ensure no VPN or proxy interferes with Facebook’s security checks. A stable connection helps prevent errors during the update process.
How to Change Phone Number in Facebook Account
To change phone number in Facebook account, start from the official website or mobile app while logged in. Go to Settings and locate the Mobile or Contact section. Replace the old number with the new one, carefully confirming the country code and all digits to avoid verification failures.
After you save the change, Facebook sends a code to the new number. Enter this code promptly to complete verification. If SMS fails, you can use an authentication app or backup email. Accurate updating of your contact details makes recovery easier if you ever get locked out.
Managing Notification and Security Settings
Once you change phone number in Facebook account, review which alerts use that number. Turn on login alerts and two-factor authentication for stronger protection. These steps ensure that future changes, logins, and security notices reach the right contact information.
Optional: Add a Second Recovery Method
For better account security, add an email or a trusted contact as an extra recovery option. This helps if your phone number changes again or becomes unavailable. Keep your security settings up to date to reduce future access issues.
Troubleshooting Common Issues
If you cannot receive the code, check that the new number is active and capable of receiving SMS. Ensure the correct country code is used and that you are not blocked by carrier filters. If the problem continues, use the account recovery flow or contact support with valid identification.
Securing Your Facebook Account After Updating Contact Info

- Always verify the new number by entering the full code sent by Facebook

- Enable two-factor authentication immediately after updating contact info

FAQ
Reader questions
Will changing my phone number lock me out of my account?
No, changing your phone number correctly keeps your account accessible. Make sure you enter the new number exactly and complete verification before closing the old number. If you already lost access, use the recovery options on the login screen.
Can I use a landline number instead of a mobile number?
Facebook primarily requires a mobile number for verification and security alerts. A landline usually cannot receive SMS codes, so it is not recommended. Use an active mobile number to ensure smooth verification and login notifications.
How do I update the number if I no longer have the old phone?
If you cannot access the old number, start the account recovery process on the Facebook login page. Provide details such as your email, full name, and other information to verify your identity. Facebook support will guide you to regain access and update your phone number.
Can I add more than one phone number to my account?
You can add a secondary phone number as an alternate contact, but one number serves as the primary for login and security alerts. The secondary number helps with recovery and confirms your identity if the primary number is unavailable.
