You can change your birth date in TikTok settings, but the platform restricts how often you can do it

TikTok stores your birth date in your account settings and uses it to control what content you see and who can contact you. If you entered the wrong date when you signed up, or your circumstances have changed, you can update it yourself through the app or website. However, TikTok limits age changes to once every 90 days, so the change won't take effect when ready if you've modified it recently.

The process takes about two minutes and requires you to be logged into your account. You'll need access to the email or phone number associated with your TikTok account, because TikTok may ask you to verify your identity before confirming the change.

Key Takeaways

  • You can change your birth date through Account Settings on the TikTok app or website by going to Personal Information and selecting Date of Birth.
  • TikTok enforces a 90-day waiting period between age changes, so if you've modified your birth date recently, you won't be able to change it again until that period passes.
  • If you're under 18, changing your age to 18 or older will remove restrictions on who can message you and what content appears in your feed.
  • If you created your account with a false birth date to bypass age restrictions, TikTok may suspend or delete your account if detected.

How to change your birth date on the TikTok app

Open TikTok and tap the profile icon in the bottom right corner. This takes you to your profile page. Tap the three horizontal lines (called a menu icon) in the top right corner, then select Settings and Privacy.

In Settings and Privacy, tap Account, then Personal Information. You'll see a field labeled Date of Birth with your current date. Tap on it to open the date picker. Select your correct birth month, day, and year, then tap Save or Confirm. TikTok will ask you to verify your identity — you may receive a code via email or text message. Enter that code to complete the change.

How to change your birth date on the TikTok website

Go to tiktok.com and log into your account. Click your profile picture in the top right corner and select Settings and Privacy from the dropdown menu. Click Account, then Personal Information. You'll see your current Date of Birth listed. Click on the date field to edit it, select your correct birth month, day, and year, then click Save.

TikTok will send a verification code to the email address or phone number on file. Check your email inbox or text messages for the code, enter it on the confirmation screen, and your age change will be complete. If you don't receive a code within a few minutes, check your spam folder or request a new code.

What happens when you change your age

If you change your age from under 18 to 18 or older, your account restrictions will lift. This means other users can send you direct messages, your videos may be recommended to a wider audience, and you'll see content marked for mature audiences. If you change your age from 18 or older to under 18, TikTok will restrict who can message you — only people you follow can send you direct messages, and your account becomes more private.

The change takes effect when ready after verification, but TikTok won't let you change your birth date again for 90 days. This restriction exists to prevent users from repeatedly switching between age groups to bypass content filters or privacy settings.

Why TikTok asks for your birth date

TikTok uses your birth date to enforce age-appropriate content rules and to protect younger users. Users under 13 cannot create accounts at all — if you try, TikTok will reject the signup. Users between 13 and 17 have restricted messaging, limited discoverability, and cannot go live or receive gifts. Users 18 and older have access to all features.

Your birth date also affects what ads you see and whether you can participate in certain features like TikTok Shop or creator monetization programs. Some features are only available to users 18 or older due to legal requirements in different countries.

What to do if you can't change your age

If you see a message saying you can't change your birth date, you likely hit the 90-day limit. TikTok enforces this cooldown strictly — you'll have to wait until the 90 days have passed since your last change. There is no way to bypass this waiting period through customer support.

If you're having trouble with the verification code, make sure you're checking the email address or phone number associated with your account. Check your spam folder, and if the code still doesn't arrive, request a new one. If verification fails repeatedly, try changing your birth date on the TikTok website instead of the app, or log out completely and log back in before trying again.

Important: Don't create accounts with false ages

If you created your TikTok account using a false birth date to bypass age restrictions, changing it later won't erase that history. TikTok's systems track account behavior and can detect patterns that suggest age misrepresentation — such as an account created with an age under 13, or repeated age changes within short timeframes.

If TikTok determines you violated age requirements when you signed up, your account may be suspended or permanently deleted. This is especially true for accounts created by minors who falsified their age to access features restricted to adults. The safest approach is to use your real birth date from the start.

Frequently Asked Questions

Can I change my age more than once?

Yes, but only once every 90 days. TikTok enforces this limit to prevent users from switching between age groups to bypass content restrictions. If you try to change your age before 90 days have passed since your last change, you'll see an error message telling you when you can change it again.

What if I entered my birth date wrong by accident?

You can correct it through Personal Information in your account settings. Follow the same steps as changing your age, and TikTok will ask you to verify your identity. Once verified, the corrected birth date takes effect when ready, and you'll have to wait 90 days before making another change.

Will changing my age affect my videos or followers?

Your videos and followers stay the same. Changing your age only affects what content you can see, who can message you, and what features you can access. Your upload history and follower count are not deleted or hidden.

What if I'm under 18 and want to change my age to 18?

You can change it in your settings, but TikTok may ask for additional verification if the change seems suspicious — for example, if your account was recently created or if you've made multiple age changes. Be honest about your actual birth date, because falsifying your age violates TikTok's terms of service.

Can I change my age if my account is restricted or suspended?

If your account is suspended, you won't be able to access settings until the suspension is lifted. If your account is restricted due to age verification issues, contact TikTok support through the app or website to resolve the restriction before attempting to change your birth date.
