Change your birthday in TikTok settings on any device in under a minute

Open TikTok and tap your profile icon in the bottom right corner. Tap the three horizontal lines (menu icon) in the top right. Scroll down and tap Settings and privacy, then tap Account. Tap Date of birth and enter your correct birthday using the date picker. Tap Save or Confirm depending on your device. The change takes effect when ready.

If you are on a computer, log into TikTok.com, click your profile picture in the top right, click Settings and privacy, then click Account. Click Date of birth, enter the correct date, and click Save.

Key Takeaways

  • You can change your birthday through Settings and privacy > Account > Date of birth on both mobile and desktop versions of TikTok.
  • TikTok may restrict how often you can change your birthday, so make sure you enter the correct date the first time.
  • Your age category on TikTok affects what content you see and what features are available to you, so an incorrect birthday may limit your account.
  • If you created your account with a false birthday to bypass age restrictions, changing it now may lock certain features until you reach the actual age requirement.

Why TikTok asks for your birthday

TikTok uses your birthday to determine your age category and control which features you can access. Users under 13 cannot create accounts at all. Users aged 13 to 17 have restricted messaging, limited comment visibility, and cannot go live. Users 18 and older have full access to all features.

Your birthday also affects the content TikTok recommends to you. If your age is wrong, you may see videos meant for a different age group, or you may be blocked from features you should be able to use.

What happens if you entered a fake birthday when you signed up

If you created your TikTok account with an incorrect birthday to bypass age restrictions, changing it now may trigger account limitations. TikTok's system may lock you out of certain features until your actual age matches the requirement for that feature.

For example, if you entered a birthday that made you 18 when you were actually 15, and you now change it to your real age, TikTok may disable live streaming, direct messaging, or other age-gated features until you turn 18. This lock typically lasts until your real birthday arrives.

How often you can change your birthday

TikTok allows you to change your birthday, but the platform limits how frequently you can do so. You cannot change it every day or multiple times per week. If you try to change it too often, TikTok will show an error message telling you to wait before making another change.

The exact waiting period is not published by TikTok, but users report waiting anywhere from a few days to 30 days between changes. Enter your correct birthday the first time to avoid this restriction.

Troubleshooting: birthday option is grayed out or missing

If you cannot find or tap the Date of birth option, your account may have restrictions in place. This happens most often if you recently changed your birthday and TikTok is enforcing a cooldown period. Wait several days and try again.

If the option remains unavailable, try logging out completely, closing the app, and logging back in. On desktop, clear your browser cache and cookies, then log back into TikTok.com. If the problem persists, contact TikTok support through the app by tapping the menu icon, scrolling to Help, and selecting Report a problem.

What information TikTok sees and stores

TikTok stores your birthday in your account settings, but it does not display your birthday publicly on your profile. Other users cannot see when you were born. Only you and TikTok's systems can view this information.

TikTok uses your birthday to enforce age restrictions and customize your experience, but the company does not use it to send birthday notifications or promotional messages unless you separately turn on birthday reminders in your notification settings.

Changing your birthday on a linked account

If you signed up for TikTok using your Google, Apple, or Facebook account, you can still change your birthday directly in TikTok settings. The birthday stored in your TikTok account is separate from the birthday in your Google, Apple, or Facebook profile, so changing one does not affect the other.

If you want to update the birthday on your Google, Apple, or Facebook account as well, you will need to go to those platforms separately. Log into each platform and update the birthday in their account settings.

Frequently Asked Questions

Can I change my birthday if I am under 13?

No. TikTok does not allow users under 13 to create accounts in the first place. If your account shows a birthday under 13, TikTok will disable your account. You must be at least 13 years old to use TikTok.

Will changing my birthday affect my videos or followers?

No. Changing your birthday does not delete your videos, remove your followers, or change your username. It only affects which features you can access and what content TikTok recommends to you.

What if I do not remember my real birthday?

Enter the birthday you have on file with other services like your email account, bank, or school records. TikTok does not verify your birthday against government documents, so it accepts whatever date you enter. Make sure it matches your real age so you have access to the features you need.

Can I hide my birthday from other users?

Yes. Your birthday is never visible on your public profile. Only you can see it in your account settings. Other users cannot find out when you were born from your TikTok profile.

How long does it take for a birthday change to take effect?

The change takes effect when ready after you tap Save or Confirm. You should see the updated age category and available features right away. If you do not see changes within a few minutes, try logging out and back in.
