You can change your TikTok username directly in the app settings, and it takes about two minutes

Open TikTok and tap the profile icon at the bottom right of your screen. Go to the three horizontal lines (menu) at the top right, then select Settings and privacy. Tap Account, then Username, and type your new name. TikTok will tell you immediately if the name is already taken or contains blocked words. Hit Save when you are done.

Your new username appears on your profile right away. Anyone who had your old username as a saved link will see a "user not found" message, but your followers stay with you — they follow your account, not your username. If you change your mind later, you can change it again using the same steps.

Key Takeaways

  • You change your username in Settings and privacy > Account > Username, not in your profile edit section.
  • TikTok tells you instantly whether a name is taken or blocked, so you do not have to guess.
  • Your followers stay with your account when you change your username — they are not lost.
  • You can change your username as often as you want, with no waiting period between changes.
  • Old links to your profile will break, but direct messages and tags from friends still work.

What happens to your old username

When you change your username, TikTok releases your old one back into the pool. Someone else can claim it after you let it go. If you think you might want it back later, you should not change it unless you are sure — there is no way to reserve an old username or get it back once another person takes it.

Videos you posted under your old username stay on your account and keep their view counts. The username shown on those videos updates to your new one. Links that people saved pointing to your old profile will not work anymore, but anyone who follows you will still see your content in their feed.

Usernames TikTok will not let you use

TikTok blocks certain words and phrases from usernames. The app will not tell you why a name is rejected — it just says the username is unavailable. Common reasons include profanity, slurs, or words that TikTok associates with spam or impersonation.

If your chosen name gets blocked, try adding a number, underscore, or period to it. For example, if "musiclover" is blocked, try "musiclover_" or "musiclover2". You can also try a completely different variation. There is no official list of blocked words, so you may need to experiment.

Changing your display name instead of your username

TikTok has two separate name fields: your username (the one that starts with @ and appears in links) and your display name (the one that shows above your bio). Many people confuse these two.

If you only want to change how your name appears on your profile without changing your @ handle, edit your display name instead. Go to your profile, tap Edit profile, and change the name field at the top. This change takes effect immediately and does not affect your username or any links to your account.

What to do if you cannot access the username setting

If the username option is grayed out or missing from your settings, your account may be too new. TikTok sometimes locks the username setting for accounts less than a few days old. Wait a day or two and try again.

If you have a business or creator account, the steps are the same, but the menu path might be slightly different depending on your TikTok version. Make sure you are on the latest version of the app by checking your phone's app store. If the setting is still missing after updating, try logging out and back in.

Usernames with special characters and numbers

TikTok usernames can contain letters, numbers, underscores, and periods. You cannot use spaces, hyphens, or other special characters. Usernames are not case-sensitive — "MusicLover" and "musiclover" are treated as the same account.

The shortest username TikTok allows is two characters. The longest is 24 characters. If your desired name is too long, you will need to shorten it or use abbreviations.

Frequently Asked Questions

Will my followers see that I changed my username?

Your followers will not get a notification about the change. They will simply see your new username the next time they visit your profile or see your content in their feed. Their follow status does not change — they remain subscribed to your account.

Can I change my username back to one I used before?

Only if no one else has claimed it. Once you change away from a username, TikTok releases it immediately. If someone else takes it, you cannot get it back. If it is still unclaimed, you can reclaim it using the same steps to change your username.

How often can I change my username?

TikTok does not limit how often you change your username. You can change it as many times as you want with no waiting period. However, changing it very frequently may confuse your followers, so most people change it only when necessary.

What if someone else has the username I want?

You cannot take someone else's username. If it is taken, you will need to choose a different name. You can try adding numbers, underscores, or periods to your preferred name to create a variation that might be available.

Does changing my username affect my videos or watch history?

No. Your videos stay on your account with the same view counts and comments. Your watch history and liked videos remain unchanged. Only the name displayed on your profile and in links changes.
