You can change your birthday in TikTok's account settings, but only if your account is less than 30 days old
TikTok lets you edit your birthday through the app or website, but with a significant limit: you can only change it if you set up your account within the last 30 days. After that window closes, TikTok locks your birthday and won't let you alter it, even if you made a typo when signing up.
If you're within that 30-day window, the process takes about two minutes. If you're past it, you'll need to contact TikTok's support team, and they may or may not grant the change depending on the reason you're requesting it.
Key Takeaways
- You can change your birthday freely only in the first 30 days after creating your TikTok account.
- After 30 days, TikTok locks your birthday and you cannot change it yourself through settings.
- To change your birthday within the 30-day window, go to Profile, tap the three lines, select Account, then Birthday, and enter the new date.
- If your account is older than 30 days, you can contact TikTok Support through the app and request a change, though approval is not may provide.
How to change your birthday if your account is less than 30 days old
Open the TikTok app and tap the profile icon at the bottom right of your screen. This takes you to your profile page. Tap the three horizontal lines (called a menu icon) in the top right corner.
Select Account from the menu that appears. Scroll down until you see Birthday and tap it. Enter your correct birthday using the date picker that appears, then tap Save or Confirm depending on your device. The change takes effect immediately.
If you're using TikTok on a web browser instead of the app, log in to your account, click your profile picture in the top right, select Settings and privacy, then Account, then Personal information, and you'll find the birthday field there.
What happens after 30 days: why TikTok locks your birthday
TikTok's 30-day lock exists partly for safety reasons. Your birthday is tied to age verification, which determines what content you can see and whether certain features are available to you. Allowing unlimited changes after account creation could let someone misrepresent their age to access restricted content or features.
The lock also prevents account takeover scenarios where someone gains access to your account and changes your birthday to lock you out of your own account or alter your account settings in ways that are hard to reverse.
How to request a birthday change if your account is older than 30 days
Open TikTok and go to your profile. Tap the three lines menu, then Settings and privacy, then Help. Select Report a problem and choose Account and profile from the category list.
In the description box, explain that you need to change your birthday because you entered it incorrectly when you created your account. Be specific: say something like "I entered my birthday as January 15, 2005, but it should be January 15, 2006" rather than just "my birthday is wrong." Include the correct birthday you want on file.
TikTok Support will review your request. They may ask for additional information or may deny the request if they suspect the change is being used to misrepresent your age. There is no may provide timeline for a response, though many users report hearing back within a few days to a week.
Why your birthday matters on TikTok
Your birthday determines your age on TikTok's system, which controls what you see and what you can do. If you're under 18, certain features like direct messaging and the ability to go live are restricted. If you're under 13, TikTok's terms of service say you shouldn't have an account at all, though the app doesn't actively verify ages.
Your birthday also affects what content TikTok recommends to you. The algorithm takes age into account when deciding which videos to show you, so an incorrect birthday could mean you're seeing content intended for a different age group.
What to do if you can't remember your original birthday
If you created your account years ago and genuinely cannot remember what birthday you entered, you can still contact TikTok Support using the same process described above. When you explain the situation, be honest: say you created the account a long time ago and don't recall what you entered, and provide the birthday you believe is correct.
TikTok may ask you to verify your identity in other ways, such as confirming the email or phone number attached to your account, or they may ask you to provide context about why the birthday needs to change. Having this information ready before you submit your request can speed up the process.
Frequently Asked Questions
Can I change my birthday more than once?
Within the first 30 days, yes—you can change it as many times as you want. After 30 days, you cannot change it yourself at all. If TikTok Support grants a change after that point, it's typically a one-time exception, and you likely won't be able to change it again.
What if I entered my birthday wrong on purpose to create an account when I was too young?
TikTok's support team can usually tell when a birthday change request is being used to misrepresent age, and they will likely deny it. If you're now old enough and want your real birthday on file, you can try requesting it, but be prepared for the request to be refused.
Does changing my birthday affect my followers or videos?
No. Changing your birthday does not delete your videos, followers, or any other account data. It only updates the age TikTok has on file for you, which may change what content recommendations you receive and what features are available to you.
How long does it take TikTok Support to respond to a birthday change request?
There is no official timeline. Most users report responses within a few days to a week, but some requests take longer or receive no response at all. If you don't hear back after two weeks, you can submit another request.
Can I change my birthday if my account is linked to another platform like Instagram or Google?
Yes. Your birthday on TikTok is separate from your birthday on other platforms. Changing it on TikTok does not affect your accounts elsewhere, and linking or unlinking other platforms does not prevent you from changing your TikTok birthday (as long as you're within the 30-day window).
