Change Your Birthday in Account Settings

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 (menu icon) in the top right, scroll down, and select Settings and privacy. From there, tap Account, then Personal information. You will see your current birthday listed — tap it to edit.

When you tap your birthday, a date picker will appear. Scroll to select your birth month, day, and year, then tap Save or Done (the button name varies by device). The change takes effect when ready. TikTok does not send a confirmation email or notification, so the update is silent on your account.

Key Takeaways

  • You can change your birthday through Settings and privacy > Account > Personal information on the TikTok app.
  • The date picker lets you adjust month, day, and year all at once — you do not have to change them separately.
  • TikTok may restrict birthday changes if you have modified it recently, so you might need to wait a period of time before changing it again.
  • Your birthday is visible only to you and TikTok unless you choose to display it on your profile.
  • If you cannot find the Personal information option, make sure you are using the latest version of the TikTok app.

Why TikTok Asks for Your Birthday

TikTok requires a birthday during account creation to verify your age. The platform uses this information to enforce age-based restrictions — for example, accounts under 13 cannot access certain features, and accounts under 18 have limits on who can message them and what content they see.

Your birthday also determines whether TikTok shows you age-restricted content and whether you can use features like live streaming or monetization. Even if you do not display your birthday publicly, TikTok stores it and uses it to control what you can do on the platform.

What Happens If You Enter the Wrong Birthday

If you entered an incorrect birthday when you created your account, you can correct it using the same steps above. TikTok does not penalize you for fixing a mistake, and the change is when ready.

However, if you change your birthday to appear older or younger than you actually are to bypass age restrictions, TikTok may detect the pattern and restrict your account. The platform monitors for repeated birthday changes, especially changes that flip your age category (for example, changing from under 13 to over 13). If you genuinely made an error, one correction is normal; multiple changes in a short time may trigger a review.

Birthday Changes and Account Restrictions

TikTok limits how often you can change your birthday. After you make a change, you typically must wait 30 to 90 days before changing it again — the exact waiting period is not published by TikTok and may vary. If you try to change your birthday before this period ends, you will see a message saying you cannot modify it yet.

This restriction exists to prevent people from repeatedly changing their age to bypass content filters or access restricted features. If you need to change your birthday again and the system blocks you, you will have to wait until the cooldown period expires.

Displaying Your Birthday on Your Profile

By default, your birthday is private — only you and TikTok can see it. If you want to show your birthday publicly on your profile, go to Settings and privacy > Account > Personal information, and toggle on Show birthday on profile (or similar wording depending on your app version).

When you display your birthday, TikTok will show it on your profile page and may send you a birthday notification on that date. You can turn this visibility off at any time using the same toggle. Changing the visibility does not change the birthday itself — it only controls whether others can see it.

Troubleshooting Birthday Change Issues

If the Personal information option does not appear in your Settings, first check that you are running the latest version of TikTok. Open your device's app store (Apple App Store or Google Play Store), search for TikTok, and tap Update if available. Then close and reopen the app.

If you still cannot find the option after updating, try logging out and logging back in. On rare occasions, a session glitch prevents the settings menu from loading fully. If the problem persists, uninstall TikTok, restart your device, and reinstall the app from your app store.

If you see an error message when trying to save your new birthday, wait a few minutes and try again — this usually indicates a temporary connection issue. If the error repeats, check that your internet connection is stable and that you have not hit the 30 to 90 day cooldown period for birthday changes.

Frequently Asked Questions

Can I change my birthday on TikTok through a web browser instead of the app?

TikTok's web version (tiktok.com) has limited account settings. You can view your birthday on the web, but you cannot change it there. You must use the mobile app to edit your birthday. Open TikTok on your phone or tablet and follow the steps in the Settings and privacy menu.

What if I do not remember my current birthday on my TikTok account?

Go to Settings and privacy > Account > Personal information to see the birthday TikTok has on file. It will display in the format your region uses (for example, MM/DD/YYYY in the United States). If you need to change it, tap the birthday field and enter the correct date.

Does changing my birthday affect my followers or my videos?

No. Changing your birthday does not delete your followers, videos, or any other account data. It only updates the date TikTok uses to determine your age and which features you can access. Your followers will not be notified of the change.

Can I hide my birthday completely so no one sees it, not even TikTok?

No. TikTok requires a birthday for every account and stores it in your account information. You cannot delete it or leave it blank. You can only choose whether to display it publicly on your profile. TikTok itself will always have access to the birthday you provided.

What should I do if TikTok says I cannot change my birthday because I am under 13?

If your account is registered as under 13, TikTok restricts many features, including the ability to change certain account details. You will need to wait until your account ages into the 13+ category (based on the birthday on file) before you can make changes. If you entered the wrong birth year and are actually 13 or older, contact TikTok support through the app's Help Center to request a review.
