Updating the contact information on TikTok when a phone number changes can prevent login and account recovery issues. In the app, go to Profile > Menu > Settings and privacy > Account > Account information > Phone number > Change phone number. After account ownership is verified, the new number is entered. As menu names may vary by version, check whether the app is up to date if the option does not appear. Access to the current number affects which method should be followed; simply entering the new number is not enough.
TikTok sends an SMS code to the new number. The correct country code must be selected; +90 should be used for numbers in Türkiye. If the code does not arrive, check the number, the phone’s signal and temporary SMS issues, and avoid sending repeated requests in quick succession. The new number being linked to another TikTok account may also prevent the change; one number may not be usable for multiple accounts at the same time.
If the old SIM card is inaccessible but the account can still be accessed, the linked email address and other verification methods should be reviewed. If no alternative verification method is offered, a support request can be submitted through the Report a problem section in the app, using accurate information demonstrating account ownership. After verification, the account is linked to the new number, and this information is used for subsequent login and security procedures.
Why it matters
The use of the phone number for login and security procedures on the account shows that the change involves more than simply updating contact information. Therefore, especially for users who have lost access to their old SIM card, the availability of a linked email address and other verification options directly affects the account recovery process. Failure to receive the SMS code, selecting the wrong country code, or the new number being linked to another account may also prevent the change from being completed. The fact that menu names may vary by version means that the same procedure may not appear on the same screen for every user. The main unresolved point is whether TikTok will offer alternative verification when the old number is inaccessible; if it does not, the user remains dependent on a support request and information demonstrating account ownership.
