Change your birth date in TikTok's account settings

To change your birth date on TikTok, open the app and go to your profile. Tap the three horizontal lines (menu) in the bottom right, then select "Settings and privacy." From there, choose "Account," then "Personal information." You'll see your current birth date listed. Tap on it to edit.

TikTok will ask you to enter your new birth date using the date picker. Once you've entered the correct date, tap "Save" or "Confirm" — the exact button name varies slightly by device and app version. The change takes effect immediately.

If you're using TikTok on a computer, the process is similar: click your profile icon in the top right, select "Settings and privacy," then "Account," then "Personal information." The date field works the same way.

Key Takeaways

  • Your birth date lives in the "Personal information" section under Account settings, accessible through the menu in your profile.
  • You can change your birth date as many times as you want, and the change shows up right away.
  • TikTok requires a birth date to create an account, but you can update it later if you entered it incorrectly.
  • The app may ask you to re-enter your password before allowing you to change personal information, depending on your account security settings.

Why TikTok asks for your birth date

TikTok collects your birth date for age verification and to enforce content restrictions. Users under 13 cannot create standard accounts — TikTok offers a separate app called TikTok for Younger Users for that age group. Users between 13 and 18 see different content recommendations and have some features restricted by default, like direct messaging and the ability to go live.

Your birth date also determines which ads you see and whether certain features are available to you. Changing your birth date will update these restrictions immediately, so if you change it to show you're older, you may suddenly see new features or content types.

What happens if you enter the wrong birth date initially

If you entered an incorrect birth date when you created your account, you can fix it anytime by following the steps above. There's no penalty for correcting it, and you don't need to contact TikTok support to make the change yourself.

However, if your account was created with a birth date showing you were under 13 at the time, TikTok may have restrictions on it that don't automatically lift when you update the date. In that case, you may need to contact TikTok's support team to have those restrictions reviewed.

Changing your birth date on a linked account

If you linked your TikTok account to another service — like Google, Facebook, or Apple — changing your birth date in TikTok won't change it in that linked account. The two accounts keep separate information.

If you want to update your birth date across multiple platforms, you'll need to change it in each one individually. For example, if you linked your Google account to TikTok, you'd need to update your birth date in Google's account settings separately from TikTok's settings.

Troubleshooting: birth date won't change

If the save button doesn't work or the date reverts after you close the app, try logging out and logging back in. Sometimes the app needs a fresh session to register the change. If you're on an older version of TikTok, update the app from your device's app store first.

If the problem persists, clear the app's cache. On Android, go to Settings > Apps > TikTok > Storage > Clear Cache. On iPhone, you'll need to delete and reinstall the app, since iOS doesn't let you clear individual app caches. After reinstalling, log back in and try updating your birth date again.

Birth date privacy and who can see it

Your birth date is not visible to other TikTok users. It's stored in your account settings and only you and TikTok can see it. Other users can see your account age (how long you've had the account), but not your actual birth date.

TikTok's privacy policy explains that they use your birth date for age-gating features and content, but they don't share it with third-party advertisers or other apps. If you're concerned about data privacy, you can review TikTok's full privacy policy in the Settings menu under "Privacy and safety."

Frequently Asked Questions

Can I change my birth date more than once?

Yes. TikTok doesn't limit how many times you can update your birth date. You can change it as often as you need to, and each change takes effect immediately. There's no waiting period or approval process.

What if I don't remember my birth date?

You'll need to enter a date to save changes. If you're unsure, enter your actual birth date or the date you originally provided when you created the account. If you can't remember either, contact TikTok support through the app's help center and explain the situation.

Does changing my birth date affect my followers or videos?

No. Changing your birth date doesn't delete your videos, followers, or any other account data. It only updates the age-related settings and content restrictions tied to your account.

Why does TikTok ask for my password when I try to change my birth date?

TikTok treats birth date as sensitive personal information and may ask you to re-enter your password before letting you change it. This is a security measure to prevent someone else from altering your account details if they gain temporary access to your phone.

Can I hide my birth date from TikTok?

No. TikTok requires a birth date to maintain your account. You must provide one, but you can keep it private from other users — it won't show on your profile or in your public information.
