Change Your Birthday in 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, and select Settings and privacy. Tap Account, then Personal information. You will see your current birthday listed — tap it to edit.
TikTok will ask you to enter your new birthday using the month, day, and year format. After you type in the correct date, tap Save or Done (the button name varies by device). The change takes effect when ready, though it may take a few minutes to show on your profile if you are viewing it from another device.
If you cannot find the birthday field, make sure you are on the latest version of TikTok. Check your device's app store — if an update is available, read it first, then return to Settings and privacy to locate Personal information.
Key Takeaways
- Your birthday is stored in the Personal information section under Account settings, not in your profile or privacy settings.
- You can change your birthday as many times as you want, and the change shows up right away on your account.
- TikTok requires your real birthday to verify your age and determine which content you can see.
- If you entered a fake birthday when you created your account, you can correct it by following the same steps.
Why TikTok Asks for Your Birthday
TikTok uses your birthday to verify your age and control what content appears in your feed. If you are under 18, TikTok restricts certain videos and limits who can message you. If you entered an incorrect birthday when you signed up, changing it now ensures you see age-appropriate content and have the right account restrictions in place.
Your birthday also determines whether your account is classified as a minor or adult account. This affects your privacy settings, who can find you through search, and whether your account can go live. If you recently turned 18 or want to update your age for any reason, changing your birthday in settings is the way to do it.
What Happens After You Change Your Birthday
Once you save your new birthday, TikTok recalculates your age category. If you changed from under 18 to 18 or older, your account may automatically shift to an adult account with different default privacy settings. You may notice changes to who can comment on your videos, who can send you direct messages, or which videos TikTok recommends to you.
If you changed your birthday to a date that makes you under 18, TikTok will explore minor account restrictions. These include limiting who can message you and hiding your account from search results unless you adjust your privacy settings. The restrictions take effect within a few minutes of saving the change.
Changing Your Birthday on Desktop
If you use TikTok on a computer, the process is similar but the menu layout is slightly different. Log into your account, click your profile picture in the top right corner, and select Settings and privacy from the dropdown menu. Click Account, then Personal information, and click on your birthday to edit it.
Enter your new birthday and click Save. The change will sync to your mobile app within a few minutes. If you are logged into TikTok on multiple devices, you only need to change your birthday once — it updates across all of them automatically.
If You Cannot Find the Birthday Field
The most common reason you cannot find your birthday in settings is that your app is outdated. Open your device's app store (Google Play for Android, App Store for iPhone), search for TikTok, and tap Update if the button appears. After the update finishes, close and reopen TikTok, then go back to Settings and privacy to try again.
If you still cannot locate the birthday field after updating, try logging out and logging back in. Tap your profile icon, scroll down, and tap Log out. Then log back in with your username and password. This refreshes your account connection and often fixes display issues with settings menus.
Changing Your Birthday if You Forgot Your Password
If you want to change your birthday but cannot remember your password, you will need to reset it first. On the TikTok login screen, tap Forgot password? TikTok will send a reset link to the email or phone number associated with your account. Follow the link, create a new password, and log back in. Then you can change your birthday using the steps above.
If you no longer have access to the email or phone number on your account, you may need to contact TikTok support. Go to your profile, tap the three lines menu, select Settings and privacy, scroll down, and tap Help. Choose Report a problem and describe that you cannot access your account recovery options. TikTok support can help you regain access.
Frequently Asked Questions
Can I change my birthday multiple times?
Yes, you can change your birthday as many times as you want. There is no limit to how often you can edit it in your Personal information settings. However, if you change it frequently, TikTok may flag your account for suspicious activity, so change it only when necessary.
Will changing my birthday affect my followers or videos?
No, changing your birthday does not delete your followers, videos, or likes. Your content stays on your account. The only thing that changes is your age category and the content restrictions or recommendations that come with it.
What if I entered my birthday wrong when I created my account?
You can correct it anytime by going to Settings and privacy, then Account, then Personal information. Tap your birthday and enter the correct date. Save the change, and your account will reflect the accurate birthday from that point forward.
Does TikTok verify that my birthday is real?
TikTok does not verify your birthday against government records or other documents. It relies on what you enter in your account settings. However, if TikTok suspects your account is being used by someone underage with a false birthday, it may restrict or suspend the account.
Can I hide my birthday from other users?
Your birthday is not displayed on your public profile, so other TikTok users cannot see it. Only you and TikTok can see your birthday. It is stored privately in your account settings and used only to determine your age category and content restrictions.
