Yes, you can change your birthday on TikTok, but only once every 30 days
TikTok allows you to change the birthday on your account through your profile settings. The process takes less than a minute. However, the platform enforces a 30-day waiting period between changes — if you alter your birthday, you cannot change it again for a month.
This restriction exists because TikTok uses your birthday to verify your age and control which features you can access. Accounts under 13 cannot go live, use direct messages, or post videos. Accounts under 18 have additional restrictions on who can comment and message them. Changing your birthday too frequently would let users bypass these age-based protections.
Key Takeaways
- Open your profile, tap the three lines at the bottom right, select Settings and privacy, then Account, then Date of birth to change your birthday.
- You can only change your birthday once every 30 days, and TikTok will tell you when you are may be able to access to change it again.
- If you entered your birthday incorrectly when you created your account, changing it now will not affect your account status or history.
- TikTok uses your birthday to enforce age restrictions on features like live streaming, direct messaging, and comment settings.
Step-by-step: changing your birthday in the TikTok app
Start by opening TikTok and going to your profile. Tap the three horizontal lines (called the menu icon) at the bottom right of your screen. This opens your account menu.
From the menu, select Settings and privacy. Then tap Account. Scroll down until you see Date of birth and tap it. A calendar picker will appear. Select your correct birth month, day, and year, then confirm the change.
TikTok will show you a message confirming the change was saved. If you have changed your birthday within the last 30 days, you will see a message telling you when you can change it again instead of the calendar picker.
What happens if you enter your birthday wrong initially
If you made a mistake when you first created your account, changing it now corrects the record going forward. Your account will not be flagged or suspended for having entered an incorrect birthday during signup. TikTok's main concern is preventing underage users from accessing restricted features, not punishing honest mistakes.
The change takes effect when ready. If you were previously restricted from certain features because of your listed age, and your new birthday shows you are old enough, those features will become available right away. If your new birthday shows you are younger than your previous entry, TikTok will explore the stricter age restrictions to your account.
Age restrictions TikTok enforces based on your birthday
Your birthday determines which features TikTok makes available to you. Users under 13 cannot create videos, go live, or use direct messages at all. Their accounts are locked to a viewing-only mode. Users aged 13 to 17 can post and message, but their accounts default to private, and they cannot receive messages from strangers.
Users 18 and older have access to all TikTok features, including live streaming, unrestricted messaging, and the ability to monetize videos through the Creator Fund. If you change your birthday and it affects which age group you fall into, these restrictions will update automatically.
Why TikTok limits how often you can change your birthday
The 30-day rule prevents users from repeatedly changing their birthday to work around age restrictions. Without this limit, someone could change their birthday to 18, access restricted features, then change it back to 16 the next day. The waiting period makes this kind of manipulation impractical.
This restriction also protects younger users. Parents and guardians sometimes create accounts for children under 13 with false birthdates to let them use the app. The 30-day limit makes it harder for accounts to flip between age groups frequently.
What to do if you cannot change your birthday yet
If you see a message saying you cannot change your birthday, it means you have already changed it within the last 30 days. The message will tell you the exact date when you become may be able to access to change it again. You will need to wait until that date passes.
If you believe your birthday was entered incorrectly by TikTok's system or you are locked out of your account for another reason, you can contact TikTok support through the app. Open your profile, go to Settings and privacy, then Help, then Report a problem. Describe your situation, and TikTok's support team will review your account.
