Where to find the age setting on TikTok

Your age on TikTok lives in your account settings, not in your profile. Open the TikTok app and tap the profile icon in the bottom right corner. Then tap the three horizontal lines (called a menu icon) in the top right. Scroll down and tap Settings and privacy.

From there, tap Account, then Personal information. You will see your date of birth listed here. This is where you change it.

Key Takeaways

  • Your date of birth is stored under Settings and privacy > Account > Personal information, not on your visible profile.
  • TikTok requires you to be at least 13 years old to have an account, and the age you enter affects what content you can see and what features are available to you.
  • You can change your birth date once every 30 days, so plan ahead if you need to update it.
  • If you cannot change your age because of an error message, you may need to wait 30 days from your last change or contact TikTok support.

The step-by-step process to update your birth date

Once you are in Personal information, tap on the date of birth field. A calendar picker will appear. Scroll through the months and years to find your correct birth date, then tap the day. TikTok will show you the age it calculates from that date.

After you select your date, tap Save or Confirm (the button name varies by device). The change takes effect when ready. You will see your new age reflected in your account settings right away, though some features may take a few minutes to update based on your new age group.

Why TikTok needs your real age

TikTok uses your age to decide what content appears in your feed and which features you can use. Users under 18 see a restricted version of the app — certain videos are filtered out, and some features like direct messaging have limits. Users 13 and older can have accounts, but users under 13 cannot.

If you enter an age that makes you younger than 13, TikTok will not let you keep the account active. The platform also uses age to enforce rules about what kinds of videos you can upload and who can interact with your content.

The 30-day waiting period between changes

TikTok limits you to changing your birth date once every 30 days. This rule exists to prevent people from repeatedly changing their age to bypass content restrictions or access features they should not have. If you try to change your age before 30 days have passed since your last change, you will see an error message telling you when you can change it again.

The 30-day timer starts from the moment you save your previous change, not from when you started the process. If you made a mistake and need to correct it right away, you will have to wait out the full 30 days.

What to do if you cannot change your age

If you see an error message when you try to change your birth date, the most common reason is that you have already changed it within the last 30 days. Check the error message — it will tell you the exact date you can change it again.

If the error persists or you see a different message, try logging out of TikTok completely, then logging back in. Sometimes a refresh fixes temporary glitches. If that does not work, you can contact TikTok support through the app by going to Settings and privacy > Help > Report a problem and describing what happened. Include the exact error message you saw.

How age affects what you see on TikTok

Users under 18 have a more limited feed than adult users. TikTok filters out videos tagged as mature or containing certain content, and it does not show videos from accounts marked as adult-only. The algorithm also avoids recommending videos about sensitive topics like alcohol, gambling, or dating apps to younger users.

Additionally, accounts belonging to users under 18 have restricted direct messaging — they can only receive messages from people they follow. Users under 16 cannot go live on TikTok at all. If you change your age from under 18 to 18 or older, these restrictions lift when ready, and your feed will begin showing a wider range of content.

Changing your age on different devices

The process is nearly identical on iPhone and Android phones. The main difference is that Android users may see slightly different button labels or menu layouts, but the path is always Settings and privacy > Account > Personal information. The calendar picker works the same way on both.

If you use TikTok on a web browser or desktop computer, you can also change your age there. Log in to your account on the TikTok website, click your profile icon in the top right, select Settings and privacy, then follow the same path to Personal information. The process is identical.

Frequently Asked Questions

Can I change my age more than once a month?

No. TikTok enforces a 30-day waiting period between changes. If you need to change it again, you must wait until 30 days have passed since your last change. The app will show you the exact date you become may be able to access to change it again.

What happens if I put in a fake age?

If you enter an age that makes you under 13, TikTok will deactivate your account because the platform does not allow accounts for users younger than 13. If you enter a fake age that keeps you 13 or older, TikTok will not catch it when ready, but changing it back will trigger the 30-day waiting period.

Will changing my age delete my videos or followers?

No. Changing your birth date does not affect your videos, followers, or any other part of your account. Your content stays exactly as it is. The only thing that changes is what content you see in your feed and which features become available to you.

Can I change my age if my account is restricted?

It depends on why your account is restricted. If TikTok restricted it because you entered an age under 13, you can change your age to 13 or older to unlock it. If your account is restricted for other reasons (like violating community guidelines), changing your age will not fix that — you would need to contact TikTok support.

Does TikTok verify that the age I enter is real?

TikTok does not verify your age against government records or other documents. It relies on what you enter. However, the platform uses other signals — like your activity patterns and the content you interact with — to flag accounts that may belong to younger users than reported.
