Update Your Phone Number on Facebook

Why You Might Need to Update Your Phone Number on Facebook

Your phone number on Facebook serves several important functions. Facebook uses phone numbers to help you recover your account if you forget your password, receive security notifications when someone tries to access your account from a new device, and for two-factor authentication — a security feature that requires you to verify your identity using your phone. Your phone number also helps Facebook prevent unauthorized access and protects your personal information from hackers.

Life changes happen frequently, and your phone number might change for many reasons. You may have switched to a new phone carrier, moved to a different area with a different region code, or simply decided to use a different number. Additionally, if you're using an old phone number you no longer have access to, it becomes impossible to receive security codes when you need them. Keeping your phone number current on Facebook ensures you can always regain access to your account when necessary.

Another reason to update your phone number involves privacy and security concerns. If you previously shared your phone number with Facebook but no longer want to use that number, updating it puts you in control of your account information. You might also want to update your number if you're concerned about a previous number being compromised or if you want to use a more secure phone line.

Facebook's notification system also relies on your phone number. While Facebook primarily sends notifications through the app and email, having an updated phone number ensures that critical security alerts can reach you through text message if needed. This multi-layer approach to communication helps protect your account from unauthorized access.

Practical takeaway: Update your phone number on Facebook whenever you get a new number, change carriers, or want to improve your account security. This keeps your recovery options current and helps protect your account from unauthorized access.

How to Find Your Phone Number Settings on Facebook

Accessing your phone number settings on Facebook differs slightly depending on whether you're using the website or the mobile app. Understanding where to find these settings is the first step toward updating your information. Facebook organizes personal information within your account settings, which is accessible from your profile menu or the main settings area.

On the Facebook website, begin by looking at the top right corner of any Facebook page. You'll see a small downward-pointing arrow or your profile picture. Click this icon to open a dropdown menu. Within this menu, you'll find a "Settings & privacy" option, which may be labeled differently depending on your region or recent Facebook updates. After clicking this option, select "Settings" to enter your account settings area. This takes you to the main settings dashboard where you can manage various aspects of your account.

Once you're in the Settings area, look for a section labeled "Personal information" or "Contact information." This section contains your email addresses and phone number. You may need to scroll through several sections to find it, as Facebook organizes settings into different categories like "Security and login," "Apps and websites," and "Privacy." The personal information section is typically one of the first categories you'll encounter.

If you're using the Facebook mobile app on your phone or tablet, the process is similar but accessed differently. Tap the menu icon — usually three horizontal lines called a "hamburger menu" — typically located at the bottom right of your screen. From there, scroll down to find "Settings & privacy," then tap "Settings." The same personal information section will appear in the app, though it may be formatted differently for the smaller screen.

Practical takeaway: Bookmark or remember the path to your settings (Menu → Settings & privacy → Settings → Personal information) so you can quickly find your phone number section whenever you need to make changes.

Step-by-Step Instructions for Updating Your Phone Number

Once you've located your personal information section, the actual process of updating your phone number is straightforward. Facebook makes this process intentionally simple to ensure all users can manage their contact information. The following steps work on both the website and mobile app, with only minor differences in appearance.

First, look for the phone number field in your personal information section. If you already have a phone number listed, you'll see it displayed with options to edit or remove it. If you don't currently have a phone number on file, you may see an "Add phone number" button or link. Click or tap on this area to enter edit mode. Facebook may ask you to confirm your password or current identity before allowing changes to this sensitive information. This security measure protects your account from unauthorized modifications.

When entering your new phone number, include the country code and area code. For example, if you're in the United States, enter your number in the format: +1 (555) 123-4567. Different countries have different phone number formats, so Facebook's system should guide you with the correct format for your location. You can usually select your country first, and the input field will adjust to show you the expected format.

After entering your new number, Facebook will typically send a verification code to that phone number. You'll receive this code as a text message within a few moments. Check your text messages and return to the Facebook screen. Enter the verification code in the field Facebook provides. This confirms that you actually have access to this phone number and helps prevent someone else from adding a phone number to your account without your knowledge.

Once you've entered the verification code correctly, Facebook will save your new phone number. You should see a confirmation message indicating the update was successful. If the code doesn't arrive, you can usually request another code or try again. Make sure you're looking at the correct phone to receive the text — if you're updating from a computer, you need to check the phone that has the new number you're adding.

Practical takeaway: Have your new phone readily available with text message access before you start the update process, so you can receive and enter the verification code immediately.

What to Do If You No Longer Have Access to Your Old Phone Number

A common problem occurs when someone wants to update their phone number on Facebook but no longer has access to their old phone number. Perhaps you switched carriers and didn't port the number, lost your phone, or canceled a line. This situation requires a different approach than a straightforward update, but Facebook provides options to handle this scenario.

If you still have access to your current Facebook account through email or password, the simplest solution is to add your new phone number as an additional contact method before removing the old one. Go through the normal update process described in the previous section, add your new phone number, and complete the verification with your new phone. Once your new number is verified and saved, you can return to your settings and remove the old phone number that you no longer have access to. This approach keeps your account secure because you're never without a verified contact method.

However, if you cannot access your Facebook account through your email or password, the situation becomes more complex. Facebook has a recovery process for this scenario. On the Facebook login page, click "Forgotten password?" or the equivalent link. Facebook will ask for your email address or phone number associated with your account. Since you can't access your old phone number, use your email address. Facebook will send recovery instructions to your email. You can use this email-based recovery process to regain access to your account, and then follow the normal steps to update your phone number.

In cases where you can't access your email or phone number, Facebook provides an identity verification process. You may need to provide a government-issued ID or other documentation to confirm you're the account owner. This process takes longer and can take several days, but Facebook provides this path specifically for situations where normal recovery methods aren't available. The Facebook Help Center contains detailed information about this identity verification process and what documentation Facebook accepts.

Practical takeaway: Keep your email address current and accessible, as it becomes your backup way to access your Facebook account if you lose access to your phone number. Before switching carriers or changing numbers, update your phone number in Facebook if possible.

Protecting Your Account After Updating Your Phone Number

Updating your phone number is an opportunity to review and strengthen your overall account security. While you're already in your settings making changes, consider implementing additional security measures that work alongside your phone number to protect your account.

Two-factor authentication is a security feature that requires a second form of verification beyond your password when you log in from a new device. Even if someone obtains your password, they cannot access your account without this second verification step. You can set up two-factor authentication using your newly updated phone number. When enabled, Facebook sends you a code via text message that you must enter to complete login. This feature significantly reduces the chances of unauthorized access. To set up two-factor authentication, go to Settings & privacy → Settings →
