Change your phone number in TikTok settings in under two minutes

To change the phone number linked to your TikTok account, open the app, tap your profile icon in the bottom right, select "Settings and privacy," then "Account," then "Phone number." Tap "Change" next to your current number, enter your new phone number, and TikTok will send a verification code to that number. Enter the code to confirm the change. The whole process takes about two minutes and doesn't affect your username, followers, or videos.

You might change your phone number because you got a new phone, switched carriers, or no longer use the old number. TikTok uses your phone number to help you recover your account if you forget your password, so keeping it current matters. If you no longer have access to your old number, you can still update it—TikTok will skip the verification step on the old number and send the code only to the new one.

Key Takeaways

  • Go to your profile, then Settings and privacy, then Account, then Phone number to find the change option.
  • TikTok sends a verification code to your new number; you must enter it to complete the change.
  • If you no longer have access to your old phone number, you can still update it without verifying the old one.
  • Changing your phone number does not change your username, password, followers, or any of your videos.
  • Keep your phone number current so you can recover your account if you forget your password.

Step-by-step: updating your phone number

Open TikTok and tap the profile icon at the bottom right of the screen. This takes you to your profile page. From there, tap the three horizontal lines (the menu icon) in the top right corner, then select "Settings and privacy."

In Settings and privacy, tap "Account." You will see a list of account options including "Phone number." Tap on "Phone number" to see your currently linked number. Next to it, you will see a "Change" button. Tap "Change."

A screen will appear asking you to enter your new phone number. Type it in, including the country code if you are outside the United States. Tap "Send code." TikTok will send a six-digit verification code to your new number via text message. This usually arrives within seconds.

Open the text message and copy the code. Return to the TikTok app and paste the code into the field that appears. Tap "Verify." Once TikTok confirms the code, your new phone number is now linked to your account. You will see a confirmation message, and you can close the settings screen.

What happens if you don't have access to your old number

If you switched phone numbers and no longer have access to your old number, you can still change it. When you tap "Change" next to your current phone number, TikTok will ask whether you still have access to that number. Select "No, I don't have access to this number."

TikTok will then skip the step of verifying your old number and move straight to asking for your new number. You will still need to verify the new number by entering the code that arrives by text message. This process is the same as the standard change, just without the old-number verification step.

Changing your number if you forgot your password

If you forgot your TikTok password and no longer have access to your old phone number, you cannot change your phone number through the normal settings route—you need to recover your account first. Go to the TikTok login screen, tap "Forgot password?", and select "Phone number" as your recovery method.

TikTok will ask you to enter the phone number currently linked to your account. If you no longer have that number, select "I don't have access to this phone number." TikTok will then ask you to verify your identity using your email address or another method. Once you have recovered your account and reset your password, you can log back in and change your phone number using the standard steps above.

Why TikTok asks for a phone number

TikTok uses your phone number as a recovery tool. If someone tries to log into your account from an unfamiliar device, or if you forget your password, TikTok can send a verification code to your phone number to confirm it is really you. This protects your account from unauthorized access.

Your phone number is also used if you enable two-factor authentication, an extra security layer that requires a code sent to your phone each time you log in from a new device. Keeping your phone number current ensures these security features work when you need them.

Changing your number on the TikTok website instead of the app

You can also change your phone number on the TikTok website if you prefer. Go to tiktok.com, log in, and click your profile icon in the top right. Select "Settings and privacy," then "Account," then "Phone number." The steps are identical to the app version: click "Change," enter your new number, and verify it with the code TikTok sends.

The website version is useful if you are on a computer or if the app is not working properly. The change takes effect when ready on both the app and the website, so you do not need to do it twice.

Common problems and what to do

The verification code is not arriving: Check that you typed your phone number correctly, including the country code. Wait a few minutes—codes sometimes take longer than expected. If it still does not arrive, tap "Resend code" to request a new one. Make sure your phone plan allows text messages and that you are not blocking messages from unknown numbers.

You entered the wrong number by mistake: Tap "Change number" on the verification screen to go back and enter a different number. You will not be charged for the code that was sent to the wrong number.

Your account is locked or you cannot access settings: If TikTok has locked your account for security reasons, you may not be able to change your phone number until you verify your identity through email or another method. Go to the login screen and tap "Forgot password?" to start the account recovery process.

Frequently Asked Questions

Does changing my phone number log me out of TikTok?

No. Changing your phone number does not log you out or require you to log back in. You stay logged in on all your devices, and the change takes effect when ready in the background.

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

No. TikTok does not allow the same phone number to be linked to more than one account at a time. If you try to add a number that is already linked to another account, TikTok will tell you the number is already in use.

What if I change my mind and want to remove my phone number?

You cannot remove your phone number entirely, but you can replace it with a different one using the steps above. TikTok requires at least one way to recover your account, so you must have either a phone number or an email address linked at all times.

Will changing my phone number affect my TikTok videos or followers?

No. Your videos, followers, likes, and all other account content remain exactly the same. Changing your phone number only updates the contact method TikTok uses to send you recovery codes and security alerts.

How long does it take for the change to take effect?

The change takes effect when ready after you enter the verification code. Your new phone number is active right away, and TikTok will use it for any future account recovery or security notifications.
