How to change phone number on TikTok: The complete, documented in-app path
- Open the TikTok app and tap Profile.
- Tap the Menu ☰ button at the top.
- Tap Settings and privacy.
- Tap Account.
- Tap User Information or Account information, then tap Phone number.
- Tap Change phone.
- Enter the new phone number, then tap Send code.

This is the only documented path inside the TikTok app for updating your linked phone number. The process works the same on any mobile device running TikTok, no separate iPhone or Android steps exist in TikTok’s official help pages. If you are looking for more TikTok tips and settings, the same menu is where you manage most account preferences.
What TikTok's help pages don't cover
The pages also do not list supported phone models, OS versions, or app versions required to change your phone number. No limit on how often you can change the number is stated, and no carrier-specific process is given, you do not need to contact your mobile provider or follow any special steps based on which carrier you use. Changing your phone number may affect linked accounts like Facebook and Instagram and require reauthorization for sharing features. Third-party apps or services that rely on your TikTok phone number for integration may lose connection when you change the number.
Troubleshooting when the steps don't work
If the in-app path does not work, TikTok’s support index shows related help under Log in and Email and phone number. However, the retrieved help pages do not provide a separate documented recovery flow for this exact issue. If two-factor authentication (2FA) is enabled, you must update your 2FA settings to link the new phone number. There may be a transition period where the old phone number remains associated with the account, so keep both numbers accessible. For TikTok Ads accounts, the path is different: go to User Settings → Personal Info → Add Phone Number or Change Phone Number, verify the current phone number with a code, then enter the new number and country code, tap Send Code, and finally Submit.
Frequently Asked Questions
Can the number be changed from the app?
Yes, the documented method is entirely inside the TikTok app, no website or separate tool is required.
Do you need to verify the current number?
For consumer TikTok accounts, the help page only confirms entering a verification code after adding the new number. For TikTok Ads accounts, changing a phone number requires verifying the current number with a verification code first.
Is there a carrier-specific TikTok number change process?
No carrier-specific process is documented on any of TikTok’s help pages. You do not need to involve your mobile provider to update your number in the app.
What if I don't have access to my old phone number?
The in-app path assumes you can receive the verification code on the old device before switching to the new one.
Can I use the same phone number on multiple TikTok accounts?
You cannot use the same phone number on multiple TikTok accounts; each account requires a unique number.
