How to change your birthday on TikTok

You can change your birthday in TikTok's account settings on your phone or computer. The process takes about two minutes: open the app, go to your profile, tap the menu icon, select "Account," then "Personal information," and update the date. TikTok will ask you to confirm the change before it saves.

The main thing to know is that TikTok limits how often you can change your birthday. You can only update it once every 30 days. If you've already changed it recently, you'll see a message telling you when you can change it again. This limit exists to prevent people from repeatedly changing their age to bypass content restrictions.

Key Takeaways

  • You can change your birthday through Account settings under Personal information, and the change takes effect immediately after confirmation.
  • TikTok enforces a 30-day waiting period between birthday changes, so you cannot update it again until that time passes.
  • If your account was created with an incorrect birthdate, you should correct it as soon as possible since TikTok uses age to control what content you see.
  • On a computer, the steps are the same: Profile > Menu > Account > Personal information > Birthday.

Steps to change your birthday on a phone

Open TikTok and tap your profile icon in the bottom right corner. This takes you to your profile page. Then tap the three horizontal lines (the menu icon) in the top right, which opens a list of options.

Scroll down and tap "Account." This opens your account settings. Next, tap "Personal information." You'll see your current birthday listed here. Tap on the birthday field to open a date picker. Select the correct month, day, and year, then tap "Save" or "Confirm" depending on your phone's operating system.

TikTok will show a confirmation screen. Review the new birthday to make sure it's correct, then tap the button to confirm the change. The update saves immediately, and you'll return to your profile.

Steps to change your birthday on a computer

Go to TikTok.com and log into your account. Click your profile icon in the top right corner, then click "Settings and privacy" from the dropdown menu. This opens your account settings page.

Click "Account" in the left sidebar. Then click "Personal information." You'll see your current birthday. Click on the birthday field to edit it. A date picker will appear — select your month, day, and year, then click "Save."

TikTok will ask you to confirm the change. Review the new date and click the confirmation button. The change takes effect right away.

Why TikTok needs your correct birthday

TikTok uses your birthdate to determine what content you can see and what features are available to you. If you're under 13, TikTok restricts your account to private by default and limits who can message you. Accounts for users 13 to 17 have different restrictions than adult accounts.

Your birthday also controls whether you can access certain features like live streaming, gifts, and direct messaging. If your birthday is set incorrectly, you might not be able to use features you should have access to, or you might see content that isn't appropriate for your actual age.

What happens if you reach the 30-day waiting period

If you try to change your birthday before 30 days have passed since your last change, TikTok will show you a message saying you can't update it yet. The message will tell you the exact date when you'll be able to change it again. You'll need to wait until that date arrives before you can make another update.

This limit applies even if you made a mistake and want to correct it right away. The only exception is if you contact TikTok support directly and explain that your account was created with incorrect information. Support may be able to override the waiting period, though there's no may provide.

If you can't find the birthday setting

Make sure you're logged into the account you want to change. If you're using a phone, update TikTok to the latest version from your app store — older versions sometimes have different menu layouts. Then try the steps again: Profile > Menu > Account > Personal information.

If you're on a computer and the Personal information option doesn't appear, try logging out and logging back in. Clear your browser's cache and cookies, then try again. If the setting still doesn't show up, you may need to use the TikTok app on a phone instead, since some account settings are only available through the mobile app.

Frequently Asked Questions

Can I change my birthday more than once a month?

No. TikTok allows one birthday change every 30 days. If you need to change it again, you must wait until the 30-day period ends. The app will show you the exact date you can make the next change.

What if I entered the wrong birthday when I created my account?

Change it as soon as you can using the steps above. Your birthday controls what content and features you see, so correcting it matters. If you've already used your one change recently, you'll need to wait for the 30-day period to end.

Does changing my birthday affect my followers or videos?

No. Changing your birthday does not delete your followers, videos, or any other account data. Only the birthday itself changes. Your followers will not be notified of the change.

Can I hide my birthday from other users?

Your birthday is private by default — other TikTok users cannot see it on your profile. Only you and TikTok can see your birthdate. It's used only to control your account settings and content restrictions.
