You can change your TikTok username once every 30 days, and the process takes about two minutes from inside the app

TikTok lets you change your username once per calendar month. If you changed it on March 15, you cannot change it again until April 15. The change happens when ready — your old username becomes available for someone else to claim after a few hours. You do this entirely within the TikTok app on your phone; there is no website version of this feature.

The username is different from your display name. Your display name is what appears above your videos and on your profile — you can change that as often as you want. Your username is the handle that starts with @, the one people use to tag you or search for you. That is the one locked to the 30-day rule.

Key Takeaways

  • Open TikTok, tap your profile icon in the bottom right, then tap the three horizontal lines and select "Settings and privacy" to reach the username field.
  • Your new username must be between 2 and 24 characters, use only letters, numbers, periods, and underscores, and cannot be a username already in use.
  • The change takes effect when ready, but your old username becomes available to others after a few hours, so do not share it with anyone you want to keep it private from.
  • If you see an error message saying you cannot change your username yet, you are still within 30 days of your last change — wait until the calendar month rolls over.

The exact steps to change your username right now

Start in the TikTok app on your phone. Tap your profile icon — it is a person's head and shoulders — in the bottom right corner of the screen. This takes you to your profile page.

Tap the three horizontal lines (called a hamburger menu) in the top right corner of your profile. A menu slides up from the bottom. Scroll down and tap "Settings and privacy." This opens a new screen with several options.

Tap "Account." You will see fields for your email, phone number, and username. The username field shows your current @handle. Tap on it. A text box appears where you can delete your old username and type a new one. Type your new username, then tap "Save" or "Confirm" — the exact button name varies by phone type.

If the save button is greyed out or you see a message like "You can change your username again on [date]," you are still within 30 days of your last change. You will have to wait until that date arrives.

Rules for what your new username can be

TikTok enforces specific rules about what characters and length are allowed. Your username must be between 2 and 24 characters long. You can use letters (uppercase and lowercase), numbers, periods, and underscores. You cannot use spaces, hyphens, or special characters like @, #, $, or &.

Your username cannot already be in use by another account. If you type something and TikTok says it is unavailable, someone else has claimed it. You can try adding a number or underscore to make it unique — for example, changing @sarah to @sarah_2024.

TikTok does not allow usernames that impersonate public figures or brands, though enforcement of this rule is inconsistent. If your account is flagged for impersonation, TikTok may force you to change your username and prevent you from using certain handles.

What happens to your old username after you change it

Your old username does not disappear when ready. For a few hours, it remains reserved and unavailable to others. After that window closes — usually between 2 and 24 hours — your old username becomes available for anyone else to claim. If you had a username you liked and want to keep it, do not change it unless you are certain you want something new.

People who followed you before the change will still see your new username on their follower list. Links to your old profile redirect to your new one for a short time, but this redirect does not last forever. If you shared your old @handle on other social media or websites, update those links to your new username so people can still find you.

Troubleshooting: why the change button might not work

The most common reason you cannot change your username is that you are still within 30 days of your last change. TikTok will show you the exact date you can change it again. Mark that date on your calendar and try again after it passes.

If you see an error message that says something like "Username unavailable" or "This username is taken," the handle you chose is already in use. Try a different combination. If you see "Invalid username," you used a character that TikTok does not allow — remove spaces, hyphens, or special characters and try again.

If the app is not responding or the save button does nothing, try closing TikTok completely and opening it again. Make sure you are using the official TikTok app from the Apple App Store or Google Play Store, not a third-party app or web version. If the problem persists, restart your phone and try once more.

Why you might want to change your username before 30 days are up

You have one change per month, so use it strategically. Common reasons to change your username include: you created an account with a placeholder name and now want something permanent, your username no longer matches your content or brand, or you want to distance yourself from an old online identity.

Because the change is permanent and your old username becomes available to others, think through your new choice before you tap save. You cannot undo a username change — you can only wait 30 days and change it again. If you are unhappy with your new username after a few hours, you will have to wait a full month to change it a second time.

Frequently Asked Questions

Can I change my username more than once in 30 days?

No. TikTok enforces a strict one-change-per-30-days limit. If you change your username on the 15th, you cannot change it again until the 15th of the following month. There is no way around this limit, even if you contact TikTok support.

What is the difference between my username and my display name?

Your display name is the text that appears above your videos and on your profile — you can change it as often as you want. Your username is your @handle, the one people use to search for you or tag you in comments. Only the username has the 30-day restriction.

If I change my username, do my followers disappear?

No. Your followers stay with you when you change your username. They will see your new @handle on their follower list, and your follower count does not change. However, if you shared your old username on other websites or social media, update those links so new people can still find you.

Can I get my old username back if someone else takes it?

Not through TikTok support. Once your old username becomes available and someone else claims it, TikTok does not remove it from that person's account to give it back to you. If the account using your old username is inactive or violates TikTok's rules, you could report it, but there is no may provide TikTok will act on it.

Why does TikTok limit username changes to once per month?

The 30-day limit prevents spam, impersonation, and account takeover fraud. If usernames could change when ready and without restriction, someone could impersonate a creator, collect followers, then switch to a new name and repeat. The monthly limit makes this tactic less profitable and easier for TikTok to detect.
