You can change your birthdate in TikTok settings, but only if your account is not restricted

TikTok lets you change the birthdate on your account through the app or website settings. The process takes about two minutes. However, if TikTok has flagged your account as underage or locked it for age verification, you cannot change the date yourself — you will need to contact TikTok support and provide proof of your real age.

The reason TikTok restricts age changes is that the platform uses your birthdate to enforce content rules. Accounts under 13 cannot post videos or go live. Accounts under 18 see different ads and have limited messaging features. If the system suspects you lied about your age when you signed up, it blocks self-service changes to prevent workarounds.

Key Takeaways

  • You can change your birthdate in TikTok settings under "Personal Information" if your account has not been flagged for age verification.
  • TikTok will not let you change your age if the app suspects you are underage or if you have already changed it recently.
  • If your account is locked for age verification, you must submit a photo ID or government document to TikTok support before you can proceed.
  • Changing your age to under 13 will immediately disable posting, live streaming, and direct messages on your account.
  • TikTok stores your real birthdate and can detect if you enter a false one, which may result in account suspension.

Change your age through the app settings

Open TikTok and tap the profile icon in the bottom right corner. Tap the three horizontal lines (menu icon) in the top right, then scroll down and tap "Settings and privacy." Tap "Account," then tap "Personal information." You will see your current birthdate listed. Tap on the date field to open the date picker.

Use the scroll wheels to select your birth month, day, and year. Tap "Confirm" or "Save" when you are done. The app will process the change immediately. If you see an error message or the button is grayed out, your account has been flagged and you cannot change the date yourself — skip to the section on account restrictions below.

Change your age on the TikTok website

Go to tiktok.com and log in to your account. Click your profile picture in the top right corner, then click "Settings and privacy." Click "Account," then click "Personal information." Click on the birthdate field to open the date picker. Select your birth month, day, and year, then click "Save."

The website version works the same way as the app. If you get a message saying you cannot change your birthdate, your account is restricted and you will need to go through the verification process described below. Do not try to change it again immediately — TikTok will flag repeated attempts as suspicious activity.

What to do if your account is locked for age verification

If TikTok blocks you from changing your age, the app will usually show a message asking you to verify your identity. Tap or click "Verify now" or "Submit ID." You will be asked to upload a photo of a government-issued ID — a driver's license, passport, state ID card, or national ID card. Take a clear photo of the front of the document and upload it through the app.

TikTok's system will scan your ID and extract your real birthdate. This process can take anywhere from a few hours to a few days. You will get a notification when verification is complete. If TikTok rejects your ID (blurry photo, expired document, or unreadable text), you can resubmit. Once verification passes, you can change your birthdate in settings as normal.

If you do not have a government ID or cannot upload one, contact TikTok support through the app. Go to "Settings and privacy," tap "Help," then tap "Report a problem." Describe your situation and ask for alternative verification methods. Response times vary, but TikTok usually replies within one to two weeks.

Why TikTok might prevent you from changing your age

TikTok restricts age changes for several reasons. If you changed your birthdate very recently (within the last 30 to 90 days), the system may not let you change it again. If you have already changed it multiple times, TikTok treats that as a sign you are trying to bypass age restrictions. If the app detected that you were underage when you created your account, it will lock the age field until you verify with ID.

TikTok also blocks age changes if your account has been reported for violating age-related policies. For example, if someone reported your account for appearing to be run by a minor, TikTok may lock the age field pending review. In these cases, verification with ID is the only way forward.

What happens after you change your age

If you change your age to under 13, TikTok will immediately disable several features on your account. You will not be able to post videos, go live, send direct messages, or comment on other videos. Your existing videos will remain on your profile but will not appear in the For You page or search results. You will also see a restricted version of the app with limited content.

If you change your age to between 13 and 17, you will regain posting and messaging features, but TikTok will apply teen-specific restrictions. You will see fewer ads, cannot receive gifts during live streams, and have limited access to certain features. If you change your age to 18 or older, all features become available and restrictions lift.

Avoid common mistakes when changing your age

Do not enter a false birthdate. TikTok's system can detect when you enter an age that does not match your ID or your account creation history. If caught, your account may be suspended or permanently banned. The verification process exists specifically to prevent this.

Do not try to change your age multiple times in a short period. If you make a mistake, wait at least a few days before trying again. Repeated changes trigger TikTok's fraud detection and can result in a temporary lock on your account.

Do not use someone else's ID to verify your age. This violates TikTok's terms of service and can result in permanent account suspension. If you cannot verify with your own ID, contact support and explain your situation honestly.

Frequently Asked Questions

Can I change my age on TikTok if I just created my account?

Yes, you can change your age immediately after creating your account if TikTok does not flag it. However, if you entered an age under 13 during signup, TikTok may lock the age field and require ID verification before you can change it.

What if I entered the wrong birthdate by accident?

You can change it through settings as long as your account is not restricted. If your account is locked, submit your real ID through the verification process. TikTok will update your birthdate once verification is complete.

How long does TikTok ID verification take?

Most verifications complete within a few hours to one business day. Some take up to three days if TikTok needs to review your submission manually. You will get a notification when the process is done.

Will changing my age delete my videos or followers?

No. Your videos and followers stay on your account. However, if you change your age to under 13, your videos will stop appearing in the For You page and search results until you change your age back.

What should I do if TikTok rejects my ID?

Make sure the photo is clear, well-lit, and shows the entire front of the document. Check that your ID is not expired. If it is still rejected, try uploading again or contact TikTok support through the app's Help section and ask about alternative verification methods.
