Change your phone number in TikTok settings in under two minutes

Open TikTok and tap the profile icon in the bottom right corner. Go to Settings and privacy, then select Account. Tap Phone number and enter your new number. TikTok will send a verification code to that number—enter it to confirm the change. Your old phone number is then replaced when ready.

The process works the same whether you're switching to a completely new phone, keeping the same device but changing carriers, or straightforward updating your contact information on file. You don't need to delete your account or start over.

Key Takeaways

  • You change your phone number through Settings and privacy > Account > Phone number, not through your phone's settings.
  • TikTok sends a verification code to your new number, so you must have access to that phone to complete the change.
  • If you no longer have access to your old phone number, you can remove it first by using a backup login method like email or username.
  • Changing your phone number does not affect your followers, videos, or account history—only your contact information on file.

What happens if you no longer have access to your old phone number

If your old number is no longer active or you don't have the phone anymore, you can still change it. Instead of going through the phone number field, log in using your email address or username and password. Once you're in your account, go to Settings and privacy > Account and remove the old phone number before adding the new one.

This matters because TikTok doesn't require a phone number to use the account—it's optional contact information. You can have an account with no phone number on file, or swap between different numbers without keeping the old one active.

Why TikTok asks for a phone number and what it's used for

TikTok uses your phone number for account recovery and security. If you forget your password or someone tries to access your account from an unfamiliar location, TikTok can send a verification code to that number to confirm it's really you. It's also used if you enable two-factor authentication, which adds an extra security layer beyond your password.

The phone number is not displayed publicly on your profile. Other users cannot see it unless you choose to share it in your bio or direct messages. TikTok does not use it for marketing calls or texts unless you separately opt into notifications.

Changing your number when you get a new phone

If you're switching to a new phone with a new number, the steps are the same: open TikTok on your new phone, go to Settings and privacy > Account > Phone number, and enter the new number. You'll receive the verification code on your new phone and can complete the change right away.

Your TikTok account itself stays exactly the same. Your username, followers, videos, and watch history all remain unchanged. The only thing that updates is the phone number TikTok has on file for account recovery purposes.

Two-factor authentication and phone number changes

If you have two-factor authentication turned on, changing your phone number is especially important. Two-factor authentication sends a code to your phone every time you log in from a new device or browser. If you change your phone number but don't update it in TikTok, you won't receive those codes and won't be able to log in.

Update your phone number first, then make sure two-factor authentication is still enabled and working. You can test it by logging out and logging back in on a different device to confirm you receive the code on your new number.

What to do if the verification code doesn't arrive

If you enter your new phone number but don't receive the verification code, wait a few minutes—sometimes it takes longer than expected. Check your spam or junk folder in case the message was filtered there. If you're using a landline or VoIP service, some of these don't receive text messages, so you may need to use a mobile number instead.

If you still don't receive the code after several minutes, try again. If the problem continues, you can contact TikTok support through the app by going to Settings and privacy > Help > Report a problem. Describe that you're unable to receive the verification code and provide your username. Support can help you verify your identity through other means.

Removing your phone number entirely

You don't have to keep a phone number on file. If you want to remove it without adding a new one, go to Settings and privacy > Account > Phone number and select the option to delete or remove it. Your account will still work normally—you'll just lose the ability to use your phone number as a login method or to receive two-factor authentication codes.

If you remove your phone number, make sure you remember your password and have access to your email address, since those become your only ways to log back in if you're ever locked out.

Frequently Asked Questions

Will changing my phone number log me out of TikTok?

No. Changing your phone number does not log you out or affect your current session. You stay logged in on all your devices, and the change only updates the contact information TikTok has on file.

Can I use the same phone number on multiple TikTok accounts?

TikTok allows one phone number per account. If you try to add a number that's already linked to another account, you'll need to remove it from the first account before you can use it on the second one.

What if I change my number but forget to update TikTok?

If you have two-factor authentication on, you won't be able to log in from new devices because you won't receive the verification codes. Log in from a device where you're already signed in, go to Settings and privacy > Account > Phone number, and update it with your new number.

Does TikTok charge money to change my phone number?

No. Changing your phone number on TikTok is free. You only pay for the text message that carries the verification code, which is a standard text message charge from your phone carrier if you have one.

Can I change my phone number if I'm locked out of my account?

If you're locked out, you cannot change your phone number until you regain access. Use your email address or username to log back in, or contact TikTok support with proof of identity to help you recover your account first.
