You can change your birthday in TikTok's account settings, but only if you haven't changed it recently

TikTok lets you update your birthday through your profile settings, but the platform limits how often you can make the change. You can modify it once every 60 days. If you've already changed it within the last two months, you'll need to wait until that window closes before you can change it again. This restriction exists partly to prevent account takeovers — someone who gains temporary access to your account can't repeatedly alter your age to hide their activity.

The process itself takes less than a minute. You go to your profile, tap the menu icon, select "Settings and privacy," then "Account," and find the birthday field. TikTok will ask you to confirm the change before it takes effect. The new birthday appears in your profile when ready, though the change may take a few minutes to show up everywhere on the platform.

Key Takeaways

  • You can change your TikTok birthday once every 60 days through Settings and privacy > Account > Birthday.
  • TikTok uses your birthday to determine which content recommendations and ads you see, so an inaccurate age can affect your feed.
  • If you entered a fake birthday when you created your account, changing it now won't trigger a review or suspension.
  • Your birthday is visible only to you and TikTok unless you choose to display it on your public profile.

Why TikTok asks for your birthday in the first place

TikTok collects your birthday for two main reasons: to comply with child protection laws and to target ads and content to your age group. In the United States, the Children's Online Privacy Protection Act (COPPA) requires platforms to verify that users under 13 are not on the service without parental consent. TikTok's terms of service require you to be at least 13 years old. The platform uses your stated age to filter which videos appear in your feed and which ads you see.

The second reason is commercial. Advertisers pay more to reach certain age groups, and TikTok's algorithm uses your age to decide which videos are likely to keep you watching. If your birthday is wrong, you may see content and ads that don't match your actual interests or age group. This is a privacy trade-off: TikTok knows your exact age, but you get a feed that's theoretically more relevant to you.

Step-by-step: how to change your birthday on TikTok

On your phone (iOS or Android): Open TikTok and tap the profile icon in the bottom right corner. Tap the menu icon (three horizontal lines) in the top right. Scroll down and tap "Settings and privacy." Tap "Account." Tap "Birthday." Enter your new date and tap "Save" or "Confirm." TikTok will show you the change and ask you to verify it before it's final.

On a computer: Go to TikTok.com and log in. Click your profile icon in the top right corner. Click "Settings and privacy." Click "Account." Click "Birthday." Enter your new date and click "Save." The process is the same, but the menu layout is slightly different because you're using a browser instead of the app.

After you save the change, wait a few minutes before checking your profile or feed. TikTok's servers need time to update the information across all of its systems. If the change doesn't appear right away, try logging out and logging back in.

What happens if you hit the 60-day limit

If you try to change your birthday and see a message saying you can't, it means you've already changed it within the last 60 days. TikTok counts from the date of your last change, not from the calendar month. So if you changed your birthday on January 15, you won't be able to change it again until March 15.

There is no way to override this limit or request an exception. You have to wait the full 60 days. If you made a mistake and need to correct it urgently, your only option is to contact TikTok's support team through the app and explain the situation. They can sometimes make exceptions for genuine errors, but they don't always grant them, and the process can take several days.

Privacy considerations: who can see your birthday

By default, your birthday is private. Only you and TikTok can see it. Other users cannot view it on your profile unless you choose to make it public. To check your privacy settings, go to Settings and privacy > Privacy > Birthday visibility. You can set it to "Only me," "Friends," or "Everyone." Most users leave it set to "Only me" because there's no real benefit to sharing your exact age with strangers on the internet.

Keep in mind that even if your birthday is private, TikTok still uses it to filter content and ads. Your age affects what you see, regardless of whether other people know it. If you're concerned about TikTok collecting this information at all, you can review what data TikTok holds about you by going to Settings and privacy > Account > read your data. This generates a file that shows everything the platform knows about you, including your birthday.

What to do if you entered a fake birthday when you signed up

Many people create TikTok accounts with incorrect birthdays — either because they were underage and wanted to use the platform, or because they didn't want to share their real age. If this is your situation, you can change it to your real birthday now without penalty. TikTok does not suspend or flag accounts for updating their birthday, even if the original entry was false.

However, if you are actually under 13, you should not have a TikTok account at all under the platform's terms of service. If you're a parent or guardian concerned about a child's account, you can contact TikTok's support team to request account removal. TikTok also offers a "Family Pairing" feature that lets parents monitor and restrict their child's account, though this requires the child to be at least 13 and to agree to the pairing.

Troubleshooting: why you might not be able to change your birthday

If you see an error message when you try to change your birthday, the most common cause is the 60-day restriction. Check when you last changed it. If that's not the issue, try logging out of TikTok completely and logging back in. Sometimes the app's cache gets stuck and prevents updates from going through.

If you're still unable to change it after logging out and back in, your account may have a security flag. This can happen if TikTok detects unusual activity, like multiple login attempts from different locations. In that case, you may need to verify your identity by entering a code sent to your email or phone number. Follow the prompts on the screen. If you still can't change your birthday after that, contact TikTok support through the app and describe the problem.

Frequently Asked Questions

Can I change my birthday more than once every 60 days?

No. TikTok enforces a 60-day waiting period between changes. If you need to change it sooner, you can contact TikTok support and explain the situation, but they don't always grant exceptions. Plan your birthday change carefully if you know you might need to update it again soon.

Will changing my birthday affect my TikTok recommendations or followers?

Your recommendations may shift because TikTok uses your age to decide which videos to show you. Your follower count and existing followers will not change. The videos you've posted will remain on your profile, and people who follow you will still see your content in their feed.

What if I don't remember what birthday I entered when I signed up?

You can see your current birthday in Settings and privacy > Account > Birthday. If you need to know what you originally entered, TikTok doesn't show that history. Just update it to your real birthday or the date you want to use going forward.

Does TikTok verify that the birthday I enter is real?

TikTok does not verify your birthday against government records or other documents. It relies on you to enter an honest date. The platform uses automated systems to flag accounts that appear to belong to users under 13, but these systems are not perfect and depend partly on the birthday you provide.

Can I delete my birthday from TikTok instead of changing it?

No. TikTok requires a birthday on every account. You cannot leave the field blank or remove the information. You must enter a date if you want to use the platform.
