Yes, you can change your age on TikTok, but the method depends on whether your account is new or established

TikTok lets you update your birthdate in your account settings, but the process and restrictions differ based on how long you've had the account and what age you originally entered. If you made a mistake when you signed up or your birthday is coming and you want the app to know the correct date, you can change it yourself through the app. However, TikTok has rules about how often you can make changes and whether the change will stick depending on your account age.

The most important thing to know upfront: if your account is less than 30 days old, you can change your age freely. If your account is older than 30 days, TikTok locks your birthdate and you cannot change it yourself through the app settings—you would need to contact TikTok support, and they may or may not approve the change depending on the reason.

Key Takeaways

  • Accounts under 30 days old can change their birthdate as many times as needed through the account settings menu.
  • Accounts older than 30 days cannot change the birthdate themselves; the field becomes locked in the app.
  • To change your age on an older account, you must contact TikTok support through the app and provide a reason for the change.
  • TikTok uses your birthdate to enforce age restrictions on certain features and content, so the change may affect what you can see and do on the platform.

How to change your age if your account is under 30 days old

Open the TikTok app and tap the profile icon in the bottom right corner. Then tap the three horizontal lines (the menu icon) in the top right. Scroll down and tap "Settings and privacy." Tap "Account," then tap "Date of birth." You will see the birthdate you entered when you signed up. Tap on it to open the date picker, select your correct birthdate, and tap "Save" or "Confirm."

The change takes effect when ready. You can change your birthdate as many times as you want during this 30-day window. After 30 days have passed since you created the account, the date of birth field will no longer be editable, and you will see a lock icon next to it instead of an edit option.

What happens after 30 days: contacting TikTok support

Once your account is older than 30 days, TikTok prevents you from editing your birthdate directly in the app. To request a change, you need to go through TikTok's support system. Open the app, go to "Settings and privacy," tap "Account," and look for "Date of birth." You should see an option to "Report a problem" or "Contact us" near the locked birthdate field—the exact wording varies depending on your app version and region.

Tap that option and explain why you need to change your age. Common reasons TikTok accepts include: you entered the wrong year by mistake when signing up, you were born on a different date than what's listed, or you entered a placeholder date and now want to correct it. TikTok support will review your request, which typically takes several days to a week. They may ask you to provide additional information or proof before they approve the change.

There is no may provide that TikTok will approve your request. If they deny it, you will receive a message explaining why. If you believe the denial was a mistake, you can submit another request, but TikTok's decision is final in most cases.

Why TikTok locks your birthdate after 30 days

TikTok uses your birthdate to control which features and content you can access. If you are under 18, certain features like direct messaging, duets, and stitches may be restricted or unavailable. If you are under 13, your account should be a "TikTok for Younger Users" account with stricter privacy and content limits. By locking the birthdate after 30 days, TikTok prevents people from changing their age to bypass these restrictions.

This also protects younger users from being pressured to change their age to access features they should not have access to yet. The 30-day window is meant to catch honest mistakes during account setup, not to allow ongoing age changes.

What changes when you update your age

Changing your birthdate may affect what you see on your For You page, which videos you can watch, and which features are available to you. If you change from an older age to a younger age, TikTok may restrict features you previously had access to. If you change from a younger age to an older age, you may gain access to features that were previously locked.

Your age may also affect whether you can go live, receive gifts during live streams, or use certain creator tools. If you are changing your age because you are actually turning a year older, the change will take effect right away—you do not have to wait for your birthday to pass.

Common mistakes to avoid when changing your age

Do not wait until after the 30-day window closes if you know your birthdate is wrong. Once that window closes, you lose the ability to change it yourself, and getting support to fix it becomes much harder. If you made a mistake during signup, fix it as soon as you realize it.

Do not try to change your age multiple times in a short period if your account is older than 30 days. Submitting repeated support requests for the same issue may result in TikTok ignoring your requests or temporarily limiting your account. Submit one clear request and wait for a response before trying again.

Do not assume that changing your age will hide your old content or change how people see you. Your birthdate is private and only visible to you and TikTok—other users cannot see it. Changing it does not affect your videos, followers, or how your profile appears to others.

If TikTok denies your request

If TikTok support denies your request to change your age, you have limited options. You can submit another request with more detailed information about why the change is necessary, but TikTok rarely reverses a denial. Some users have had success by waiting a few weeks and submitting a new request with additional context.

If you absolutely need a different age on your account and TikTok will not change it, your only real option is to create a new account with the correct birthdate. Keep in mind that creating a new account means starting over with zero followers, zero videos, and no history. This is only worth doing if the age restriction is preventing you from using a feature you need.

Frequently Asked Questions

Can I change my age back to what it was before?

If your account is under 30 days old, yes—you can change it as many times as you want. If your account is older than 30 days, you would need to contact support and explain why you want to change it back. TikTok may or may not approve this request.

Will changing my age delete my videos or followers?

No. Your videos, followers, and account history remain exactly the same. Changing your birthdate only affects which features and content you can access going forward—it does not erase anything or change how your profile looks to other users.

What if I entered a fake age when I signed up?

If your account is under 30 days old, change it to your real birthdate right away. If your account is older than 30 days, contact TikTok support and explain that you entered an incorrect age during signup. Be honest about why—TikTok is more likely to approve changes for genuine mistakes than for attempts to bypass age restrictions.

How long does it take TikTok to respond to an age change request?

Most requests take three to seven days, but it can take longer depending on how busy TikTok support is. You will receive a notification in the app when they respond. Check your notifications regularly so you do not miss their reply.

Can I change my age if I am under 13?

If your account is under 30 days old, yes. If your account is older than 30 days, you can request a change through support, but TikTok may be more cautious about approving age changes for accounts registered to younger users. Have a parent or guardian contact support on your behalf if possible.
