How to change your age on TikTok
You can change the birthdate on your TikTok account through your account settings, but TikTok limits how often you can make this change. If you set your birthdate when you created your account, you can update it once every 30 days. The process takes about two minutes and requires you to be logged into the app or website.
Open TikTok and tap the profile icon in the bottom right corner. Go to Settings and Privacy, then Account, then Personal Information. Tap your birthdate, enter the new date, and save. TikTok will ask you to confirm the change. Once you save it, the new birthdate takes effect when ready, which may change what content you can see and what features are available to you.
Key Takeaways
- You can change your birthdate in Settings and Privacy > Account > Personal Information, but only once every 30 days.
- Changing your age may unlock or restrict features like direct messaging, duets, and certain content categories depending on your new age.
- If you cannot change your birthdate because you hit the 30-day limit, you will have to wait until that period passes.
- TikTok uses your birthdate to enforce age-based restrictions on content and features, so the change takes effect right away.
What happens when you change your age
When you update your birthdate, TikTok's content filters and feature restrictions adjust based on your new age. If you change to a younger age, some features may become unavailable. For example, users under 13 cannot use direct messaging, and users under 18 have restricted access to certain content and cannot go live unless they have a certain number of followers.
If you change to an older age, you may gain access to features that were previously locked. The change is when ready—you do not have to log out and back in. Your For You Page may also shift to show different content aligned with the age group TikTok now associates with your account.
The 30-day waiting period between changes
TikTok enforces a 30-day cooldown between birthdate changes to prevent misuse of age-based restrictions. This means if you changed your birthdate today, you cannot change it again for 30 days from that date. The timer resets each time you make a change, so if you change your birthdate on January 15, you cannot change it again until February 14.
If you try to change your birthdate before the 30 days are up, TikTok will show you a message telling you when you can make the next change. There is no way to bypass this waiting period, so plan your change carefully if you need to update your age.
Changing your age on the TikTok website versus the app
The steps are nearly identical whether you use the TikTok app or the website, but the layout is slightly different. On the app, tap your profile icon and go to Settings and Privacy. On the website, click your profile icon in the top right, select Settings and Privacy, then Account, then Personal Information. Both routes lead to the same birthdate field.
The 30-day restriction applies across both the app and website—if you change your birthdate on the app, you cannot change it again on the website until 30 days have passed. Your account is the same whether you access it from a phone or a computer, so the change syncs when ready.
What to do if you cannot change your age
If you see a message saying you cannot change your birthdate, you have likely hit the 30-day limit. The message will tell you the exact date when you can make another change. The only solution is to wait until that date arrives. There is no support option to bypass this restriction.
If you entered your birthdate incorrectly when you created your account and need to change it urgently, contact TikTok Support through the app. Go to Settings and Privacy, tap Help Center, then Report a Problem. Explain that your birthdate was entered incorrectly. TikTok Support may be able to help, though response times vary and they cannot may provide an exception to the 30-day rule.
Age restrictions and content you can access
TikTok uses your birthdate to determine what content and features are available to you. Users under 13 have the most restrictions: they cannot use direct messaging, cannot post videos, and see a limited For You Page. Users 13 to 17 can post and message, but cannot go live unless they meet follower requirements and cannot see certain mature content categories. Users 18 and older have access to all features and content.
Your age also affects whether you can use features like Gifts (which let viewers send money to creators), whether you can create certain types of content, and what ads you see. If you change your age, these restrictions update right away. Keep in mind that TikTok's algorithm may take a few hours to fully adjust the content on your For You Page to match your new age group.
Frequently Asked Questions
Can I change my age more than once every 30 days?
No. TikTok enforces a strict 30-day waiting period between birthdate changes. If you try to change it before 30 days have passed, you will see a message telling you when you can make the next change. There is no way to override this limit.
Will changing my age affect my followers or videos?
Your followers and videos stay on your account. Changing your age does not delete your content or cause people to unfollow you. However, your videos may appear in different recommendation feeds based on your new age, and some of your older content may become hidden from viewers in certain age groups if TikTok's filters restrict it.
What if I entered my birthdate wrong when I signed up?
You can change it through Settings and Privacy > Account > Personal Information, but you will have to wait 30 days between changes. If the error is urgent, contact TikTok Support through Help Center > Report a Problem and explain the situation. They may be able to information, though they cannot may provide an exception.
Does changing my age on TikTok change it on other apps?
No. Your TikTok birthdate is separate from your age on other platforms. Changing it on TikTok only affects your TikTok account. If you use the same email or phone number on other apps, you would need to change your age in those apps separately.
Why does TikTok have a 30-day limit on age changes?
The limit exists to prevent people from repeatedly changing their age to bypass content restrictions or access age-gated features. It is a safety measure designed to keep the platform's age-based protections in place.
