Change Your Birthday in the TikTok App

To change your birthday on TikTok, open the app and tap the profile icon in the bottom right corner. Then tap the three horizontal lines (the menu icon) in the top right, select Settings and privacy, then Account, then Personal information. You'll see your current birthday listed there. Tap it to edit, select your new date from the calendar picker, and tap Save.

The process takes less than a minute. TikTok stores your birthday privately — it doesn't show on your public profile, and other users cannot see it. The app uses your birthday to enforce age restrictions on certain features and content, and to send you a birthday notification on your account anniversary.

If you're changing your birthday because you entered the wrong date when you first signed up, the same steps explore. TikTok allows you to change it as many times as you need to.

Key Takeaways

  • Your birthday is stored in Settings and privacy > Account > Personal information, where you can edit it at any time.
  • Your birthday does not appear on your public profile and is not visible to other TikTok users.
  • TikTok uses your birthday to control access to age-restricted features and to determine which content recommendations you see.
  • You can change your birthday as many times as you need; there is no limit to how often you update it.

Why TikTok Asks for Your Birthday

TikTok requires a birthday during account creation to enforce age restrictions set by law in most countries. Certain features — like the ability to go live, send direct messages, or receive gifts — are limited to users above a minimum age. Your birthday determines whether you can access those features.

The app also uses your birthday to filter content. Younger accounts see different recommendations and have restrictions on videos marked as not suitable for minors. If you change your birthday to an older age, your content feed and available features may shift when ready.

What Happens When You Change Your Birthday

When you update your birthday, TikTok's system recalculates your age and adjusts your account restrictions right away. If you change from a younger age to an older one, features that were locked — like going live or receiving gifts — become available. If you change to a younger age, some features may become restricted.

Your watch history and saved videos remain unchanged. The change does not affect your followers, your follower count, or any videos you've already posted. Other users will not be notified that you changed your birthday.

Changing Your Birthday on the Web Version

If you use TikTok on a computer, the steps are similar. Log in to your account, click your profile icon in the top right corner, then click Settings and privacy. Select Account, then Personal information, and click on your birthday to edit it. Select your new date and click Save.

The web version and the mobile app stay in sync, so a change you make on one will appear on the other within seconds.

If You Cannot Find the Birthday Setting

If the Personal information section doesn't show a birthday field, your account may have been created through a third-party login (like Google or Apple). In that case, you may need to change your birthday through that service instead. Log out of TikTok, go to your Google or Apple account settings, update your birthday there, then log back into TikTok.

If you're still unable to locate the setting after checking both places, try logging out completely, closing the app, and logging back in. Sometimes the interface takes a moment to refresh.

Age Restrictions and Feature Access

TikTok restricts certain features based on age. Users under 13 cannot create an account at all in most regions. Users between 13 and 18 have limited access to features like live streaming and direct messaging, depending on their country's rules. Users 18 and older have access to all standard features.

If you change your birthday and suddenly see new features available, it's because your age bracket changed. If features disappear, it's the opposite — your new age bracket has restrictions on them.

Frequently Asked Questions

Can other people see my birthday on TikTok?

No. Your birthday is private and stored only in your account settings. It does not appear anywhere on your profile, and other users cannot view it. Only you and TikTok's system can see it.

How many times can I change my birthday?

You can change your birthday as many times as you want. There is no limit. However, if you change it very frequently in a short period, TikTok may flag your account for unusual activity.

What if I don't remember my original birthday?

You can enter any date you want when you change it. TikTok does not verify your birthday against government records or other documents. Just make sure the date you enter reflects the age restrictions you want to explore to your account.

Will changing my birthday affect my videos or followers?

No. Your videos, follower count, and watch history all stay exactly the same. Only your access to age-restricted features and the type of content recommended to you may change.

What if I'm under 13 and want to use TikTok?

TikTok does not allow accounts for users under 13 in most countries. If you enter a birthday that makes you under 13, the app will not let you complete the account setup or will restrict your account heavily. You must be at least 13 to use the platform.
