Change your age in TikTok settings on any device

To change your age on TikTok, open the app and go to your profile. Tap the three-line menu icon in the bottom right, then select Settings and privacy. Choose Account, then Date of birth. Enter your new date of birth and save the change. The process takes about two minutes and works the same way on iPhone, Android, and the web version of TikTok.

TikTok stores your birth date in your account settings, not in your username or profile name. This means changing it does not affect how other users see you — it only changes what TikTok's system records about you. The app uses your birth date to determine which features you can access and what content recommendations you receive.

If you cannot find the date of birth option in your settings, you may have an older version of the app. Update TikTok from your device's app store, then try again. On the web version at tiktok.com, the same menu path works: profile icon, settings, account, date of birth.

Key Takeaways

  • You can change your birth date through Settings and privacy > Account > Date of birth on any device where you use TikTok.
  • Changing your age does not change your username, profile picture, or how other users see your account — only TikTok's internal record of your birth date.
  • TikTok uses your birth date to control which features you can use, such as live streaming and direct messaging, which have age restrictions.
  • If the date of birth option does not appear, update your TikTok app to the latest version and try again.

Why TikTok asks for your birth date

TikTok requires a birth date during account creation because the platform has age-based restrictions on certain features. Users under 13 cannot create accounts at all. Users between 13 and 18 have limited access to features like direct messaging, live streaming, and the ability to receive gifts. Users 18 and older have full access to all features.

When you change your birth date, TikTok updates which features are available to you immediately. If you change your age from 16 to 18, for example, you will suddenly be able to go live and receive gifts. If you change your age downward, some features may become unavailable. TikTok does not send you a notification when you make this change — it simply updates your account permissions in the background.

What happens if you enter the wrong birth date by accident

If you entered an incorrect birth date when you created your account, you can correct it using the same method: Settings and privacy > Account > Date of birth. There is no limit to how many times you can change your birth date, and TikTok does not flag repeated changes or ask you to verify your identity.

However, if your account was created with a birth date that made you ineligible (for example, if you were under 13), TikTok may have restricted your account or sent you a warning. Changing your birth date after the fact does not automatically lift those restrictions. If your account has been flagged, you may need to contact TikTok support through the app's help center to restore full access.

Changing your age on a linked account

If you created your TikTok account using your phone number, email, or a linked social media account (Facebook, Google, Apple), you can still change your birth date through TikTok's settings. The birth date is stored in your TikTok account itself, not in the linked service. Changing it on TikTok does not affect your Facebook, Google, or Apple account.

If you linked your TikTok account to another service after creating it, the same rule applies — your TikTok birth date and your linked account's birth date are separate. You can change one without affecting the other.

Age restrictions and feature access

TikTok enforces different rules based on the age in your account settings. Users under 13 cannot use TikTok at all. Users 13 to 17 cannot go live, cannot receive gifts, and have limited direct messaging (they can only message people who follow them). Users 18 and older have no feature restrictions based on age.

Some features also depend on your account age, not just your birth date. For example, you may not be able to go live until your account has existed for at least 30 days, even if your birth date says you are 18. If a feature is unavailable, TikTok usually shows a message explaining why — either because of your age or because your account is too new.

Troubleshooting if you cannot change your birth date

If the date of birth field is grayed out or will not let you save a new date, the most common cause is an outdated app. Close TikTok completely, open your device's app store (Apple App Store or Google Play), search for TikTok, and tap Update if it is available. Restart the app and try again.

If updating does not work, try changing your birth date on the web version at tiktok.com instead of the mobile app. Log in, go to your profile, click the menu icon, select Settings and privacy, then Account, then Date of birth. If the web version works but the app does not, uninstall and reinstall the TikTok app on your phone.

If you still cannot change your birth date after updating and trying the web version, contact TikTok support. Open the app, go to Settings and privacy, tap Help, then Report a problem. Describe what happens when you try to change your birth date, and TikTok support will respond within a few days.

Frequently Asked Questions

Can I change my age on TikTok if I am under 13?

No. TikTok does not allow accounts for users under 13, and the app will not let you create an account or change your birth date to a date that would make you under 13. If your account was created with a birth date under 13, TikTok may have restricted or disabled it.

Will changing my age affect my followers or videos?

No. Changing your birth date does not change your username, profile picture, follower count, or any of your videos. Other users will not see that you changed your age. Only your access to age-restricted features changes.

How often can I change my birth date?

TikTok does not limit how many times you can change your birth date. You can change it as often as you want through your account settings. However, if you change it repeatedly in a short time, TikTok may flag your account as suspicious.

What if I forgot my birth date?

If you cannot remember the birth date you entered when you created your account, you can enter any date in the date of birth field. TikTok will accept it and update your account immediately. There is no way to see what birth date you originally entered.

Does changing my age on TikTok change my age on other apps?

No. Your TikTok birth date is separate from your birth date on Facebook, Instagram, Google, Apple, or any other service. Changing it on TikTok only affects your TikTok account and which TikTok features you can use.
