To change your age on TikTok if it was entered incorrectly, you need to contact TikTok customer support. TikTok no longer allows users to change their age in the app, but they may be able to do it for you if your age was entered incorrectly.

To contact TikTok customer support:

  1. Open the TikTok app and tap on the Profile tab.
  2. Tap on the three lines in the top-right corner of the screen.
  3. Tap on Settings and Privacy.
  4. Scroll down and tap on Report a Problem.
  5. Tap on Account and Profile.
  6. Tap on Editing Profile.
  7. Tap on Other.
  8. Tap on Need more help?.
  9. Enter a message explaining that you need to change your age and why. Be honest and upfront about the mistake, and provide any proof of your age that you may have.
  10. Tap on Send.

A customer support representative will review your request and may ask you to provide additional information. Once they have verified your age and your request, they will update your account information.

It is important to note that TikTok may not be able to change your age if it has already been verified. They also may not be able to change your age if you are under the age of 13.

Here are some tips for changing your age on TikTok:

  • Be honest and upfront about why you need to change your age.
  • Provide proof of your age if requested.
  • Be patient. It may take a few days for a customer support representative to review your request and update your account information.
