TikTok lets you change your birth date in your account settings, but the process depends on whether you've already set a birth date and how old your account says you are

If you entered your birth date when you created your account, you can update it by going to your profile, tapping the three-line menu, selecting Settings and Privacy, then Account, then Personal Information. Tap your birth date and enter the correct one. TikTok will save the change when ready.

If you never entered a birth date, TikTok will prompt you to add one the next time you try to access age-restricted features like certain videos or live streams. You'll see a screen asking for your birth date — fill it in and confirm.

The tricky part comes if TikTok thinks you're under 13. If your account was created with a birth date showing you were under 13 at signup, TikTok will not let you change it to an older age. The platform treats accounts created for children under 13 as a separate category with stricter rules, and it won't convert them to adult accounts through the settings menu. If this is your situation, you'll need to contact TikTok support to request a manual review.

Key Takeaways

  • You can change your birth date in Settings and Privacy > Account > Personal Information by tapping the date field and entering a new one.
  • If your account was created with a birth date under 13, TikTok will not let you change it to an older age through the app — you must contact support.
  • Once you change your birth date, the change takes effect right away and affects which features and content you can see.
  • TikTok may ask for your birth date again if you try to access age-restricted content, even if you've already entered one.

Step-by-step: changing your birth date in the app

Open TikTok and tap the profile icon at the bottom right of the screen. Tap the three horizontal lines (the menu icon) in the top right corner of your profile page. Scroll down and tap Settings and Privacy.

Tap Account. Tap Personal Information. You'll see your birth date listed — tap on it. A date picker will appear. Use the scroll wheels to set your month, day, and year, then tap Confirm or Done (the button name varies by device). Your new birth date is now saved.

If you don't see a birth date field in Personal Information, it means you haven't set one yet. Tap Add Birth Date or a similar prompt, then follow the same steps to enter your date.

What happens if TikTok says you're under 13

TikTok's terms of service require users to be at least 13 years old. If your account was created with a birth date showing you were under 13, the app treats it as a child account with limited features. You cannot change this through the settings menu — the app will reject any attempt to set a birth date that would make you 13 or older.

To fix this, you need to contact TikTok support directly. Go to Settings and Privacy > Help > Report a Problem. Describe the situation: explain that your account was created with an incorrect birth date and you need it corrected. Include your correct birth date in your message. TikTok support will review your request and may ask you to verify your identity with a photo ID before making the change.

This process can take several days to a few weeks. During that time, your account will remain restricted to child-account features. Once support approves the change, your account will be converted to a standard account with full access.

Why TikTok asks for your birth date

TikTok uses your birth date to determine which content you can see and which features you can use. Accounts for users under 16 have restricted direct messaging. Accounts under 18 cannot go live or receive gifts during live streams. Some videos are marked as age-restricted and won't show to users under 18.

The platform also uses your age to comply with laws like COPPA (the Children's Online Privacy Protection Act in the United States), which sets rules for how apps can collect data from children under 13. By verifying your birth date, TikTok can enforce these legal requirements.

Changing your birth date on a computer

If you use TikTok on a web browser, the process is similar. Log in to your account, click your profile picture in the top right, then click Settings and Privacy. Click Account, then Personal Information. Click on your birth date, adjust it using the date picker, and click Save.

Some features are limited on the web version of TikTok, so you may not see all the same options as in the app. If you run into trouble, switch to the mobile app to make the change, since that's where TikTok's full settings menu lives.

What to do if you can't find the birth date field

If you've looked in Settings and Privacy > Account > Personal Information and don't see a birth date option, your account may be very old or set up differently. Try logging out and back in, or try accessing settings from a different device.

If the field still doesn't appear, contact TikTok support through Settings and Privacy > Help > Report a Problem. Explain that you cannot locate the birth date field in your account settings. Support can walk you through the process or make the change on their end.

Frequently Asked Questions

Can I change my birth date more than once?

Yes, you can change your birth date as many times as you want through the settings menu, as long as your account wasn't created with a birth date under 13. TikTok does not limit how often you update it. However, if you change it frequently, the app may flag your account for review.

What if I don't remember my birth date?

You'll need to enter your actual birth date when prompted. If you genuinely cannot remember it, contact TikTok support and explain the situation. They may ask you to verify your identity with a government ID before updating your account.

Does changing my birth date affect my followers or videos?

No. Changing your birth date does not delete your followers, videos, or any other account data. It only changes which features and content are available to you going forward.

How long does it take TikTok support to fix a birth date?

If your account was created with a birth date under 13 and you contact support, the review typically takes three to ten business days. During that time, your account remains restricted. Support may ask for additional information or identity verification, which can extend the timeline.

Will TikTok ask me to verify my birth date with ID?

TikTok may ask for ID verification if you contact support to change a birth date, especially if your account was created as a child account. They typically accept a photo of a government-issued ID like a driver's license or passport. The ID does not need to be current, but it must match the name on your TikTok account.
