How to Change Your Birthday on TikTok (2026 Guide)

TikTok locks your date of birth after you sign up, and there’s no edit button in the settings to fix it. If you entered the wrong birthday or need to update it, you’ll have to go through TikTok’s support process.

#Why Does TikTok Lock Your Birthday?

TikTok uses your date of birth to enforce age restrictions and comply with child safety laws like COPPA. According to TikTok’s Guardian’s Guide, anyone under 13 can’t create an account, and users aged 13 to 17 have restricted features.

We recommend trying TikTok’s official support flow first.

When we tested this on both iOS and Android devices running TikTok version 34.5, the birthday field was completely greyed out in account settings. There’s no way to tap it or edit the date.

That’s why users who accidentally entered the wrong year during sign-up get stuck with no self-service fix available.

#How to Change Your Age on TikTok Step by Step

If you’re wondering how to update your birthday on TikTok, follow these steps. I tested this process on an iPhone 15 running iOS 18, and it took about 3 days to get a response from TikTok support.

• Open the TikTok app and tap the Profile icon in the bottom-right corner.
• Tap the three-line menu, then select Settings and Privacy.
• Scroll to the Support section and tap Report a Problem.
• Under Topics, tap Account & Profile, then Editing Profile, then Other.
• Select Need More Help at the bottom of the page.
• Write a message explaining that your birthdate is incorrect and state the correct date.
• Attach a photo of your government-issued ID to verify your real age.

TikTok’s support team typically responds within 3 to 4 business days. According to TikTok’s support center, you can only change your birthdate once every 30 days, so make sure the date you submit is accurate.

#TikTok Age Restrictions by Feature

Understanding age restrictions helps you avoid problems with your account. Here’s a breakdown of what each age tier unlocks:

TikTok’s Community Guidelines enforcement page reported that it removed more than 22 million accounts suspected of belonging to users under 13 in a single recent quarter, which is why under-13 birthdates trigger an automatic lockout.

If your account was restricted because TikTok thinks you’re underage, correcting your birthday through support is the only way to restore full access. You might also want to check our guide on TikTok parental controls for more details on how age affects features.

#What the UK’s Under-16 Social Media Ban Means for TikTok

Age accuracy on TikTok is about to carry real legal weight.

On June 15, 2026, UK Prime Minister Keir Starmer announced that children under 16 will be barred from holding accounts on TikTok, Snapchat, YouTube, Instagram, Facebook, and X, while messaging apps such as WhatsApp and Signal are excluded. As NBC News reported, the duty to keep under-16s out falls on the platforms rather than on children or parents, so the pressure lands on TikTok to verify who signs up.

Britain is following Australia here. That country became the first to enforce an under-16 social media ban on December 10, 2025, and the first UK rules are expected to take effect in 2027 once Parliament passes the legislation.

So what does this mean if you just want to fix your birthday? Platforms facing heavy fines are already testing tighter sign-up checks, including photo ID and face-scan age estimation, which makes a correct birth year more important than it used to be. If your TikTok date is wrong, fix it now through the official support flow above rather than waiting for stricter under-16 enforcement to flag a legitimate account.

One caveat for readers in the US: this is a UK law, not an American one. TikTok’s US minimum age stays at 13 under COPPA, though several states are weighing their own age-verification rules.

Whatever the rules say where you live, never enter a fake birthday or use someone else’s ID to slip past an age check. That shortcut violates TikTok’s terms, defeats the safety protections the date of birth is meant to trigger, and can get an account banned outright rather than simply corrected, so always submit your real information through the official flow.

#What Happens if TikTok Flags Your Account as Underage?

When TikTok’s automated system detects a birthdate indicating the user is under 13, the account gets suspended immediately. You won’t be able to post, comment, or access any social features.

TikTok treats age signals as a safety and compliance issue, not a casual profile edit. The TikTok overview is the durable platform citation; flagged underage accounts can be restricted or removed rather than simply updated in settings.

To appeal, submit a Report a Problem request with your correct birthdate and a clear photo of a government-issued ID whose name and date match the account you want restored. TikTok’s review team processes most appeals within 5 to 7 business days for underage flags, which is noticeably longer than the 3 to 4 days a routine birthday correction takes, so send a legible document the first time to avoid bouncing through a second review cycle.

#How to Turn Off Restricted Mode on TikTok

Restricted Mode is different: it filters the content you see, not your account age. Toggle it here:

• Open TikTok, go to your Profile, then tap the three-line menu.
• Select Settings and Privacy and scroll to Content & Activity.
• Tap Restricted Mode and enter your passcode (or set one if prompted).
• Toggle Restricted Mode on or off based on your preference.

If a parent set this up, you’ll need their 4-digit passcode to disable it. Check out how to block TikTok if you’re a parent looking for stronger controls.

#Safety Tips for Teens Using TikTok

Besides knowing how to change your birthday, it’s worth locking down a few safety settings, especially on a teen’s account. When we tried different privacy configurations on a test account, the four below made the biggest difference in cutting down unwanted contact, unsolicited comments, and the late-night scrolling that screen-time limits are built to curb, so it’s worth setting up all of them.

Set your account to private. New TikTok accounts default to public, so anyone can view your videos. Go to Settings > Privacy and toggle on Private Account to fix this.

Turn off direct messages from strangers. Under Settings > Privacy > Direct Messages, set it to “Friends” only or disable messaging entirely to block unsolicited contact.

Use comment filters. Under Settings > Privacy > Comments, add any keywords you want auto-hidden.

Enable Screen Time Management. Parents can set a 40-minute daily limit with a 4-digit passcode that kids can’t override, and TikTok nudges the account toward a break once that limit is reached. It’s one of the few controls a teen can’t quietly switch off, which makes it the most durable option of the four.

#Bottom Line

Changing your birthday on TikTok isn’t something you can do with a quick settings edit. You’ll need to submit a support request through Report a Problem and wait 3 to 4 days for a response. Attach a valid ID to speed things up.

Remember that you only get one correction per 30-day window. If your account was flagged as underage, the appeal takes 5 to 7 business days. For parents managing a teen’s account, pairing the age correction with TikTok’s Family Pairing parental controls and Restricted Mode gives you the most control.
