TikTok Username Checker

By FreeUsername · Reviewed October 13, 2026 · Editorial policy

On TikTok, the username is the @name in tiktok.com/@name and in every duet, stitch and comment. Because you can only change it once every 30 days, it pays to check a name before you commit. Enter one below to look it up, then compare it with TikTok's own rules.

TikTok username rules

Length	2 to 24 characters.
Allowed characters	Letters, numbers, underscores and periods.
Periods	A username cannot end with a period.
Change frequency	Once every 30 days.

TikTok username checker: a search for @yourname showing whether the TikTok username is taken or available

How to check a TikTok username

Type the name without the @. Anything longer than 24 characters, or ending in a period, can be ruled out before you even search.
We look the name up through TikTok's public embed endpoint for tiktok.com/@<name>. TikTok sometimes answers automated lookups with a challenge page, and then you will see "Blocked" rather than a real answer.
Check by hand by opening tiktok.com/@<name>. "Couldn't find this account" points to a free name, though banned and private accounts can behave differently.
The app is the final test: Profile, Edit profile, Username. TikTok tells you right away if someone already has it.

TikTok username taken? What you can do

Add an underscore or a period in the middle (not at the end), for example its.mia or mia_draws.
Add what you post about: mia.bakes, miacooks, or a city tag. Niche words also help people find you in search.
If an account is using your trademark or pretending to be you, report it through TikTok's in-app impersonation or intellectual property reporting tools instead of trying to buy the name.
Because changes are limited to once every 30 days, park on a good variation now and check back later instead of switching repeatedly.

How to change your TikTok username

Open TikTok and tap Profile at the bottom.
Tap Edit profile, then Username.
Enter the new name and tap Save. You can do this again only after 30 days.

Reserved and restricted names

Usernames must follow TikTok's Community Guidelines, so offensive names and names that pose as another person, creator or brand can be refused or reset. Accounts that impersonate others can be reported in the app.

Tips

Your old link stops pointing at you after a change, so update the link in your other bios on the same day.
Underscores are hard to hear when a name is read aloud in a video; periods are easier to say ("mia dot bakes").
Your display name can be changed separately and more freely, so put spaces, emoji or a full name there instead of in the username.

Frequently asked questions

How do I find someone on TikTok?

If you know their handle, type it above or open tiktok.com/@name in any browser; that works as a TikTok search by username without the app. Inside TikTok, the search bar also matches display names. We cannot find a TikTok user by real name, phone number or email.

How do I find a TikTok user by username?

Type the handle in the box above. The check runs from your own browser against TikTok’s public embed endpoint and shows whether a profile answers at tiktok.com/@name, with a link to open it. It only finds exact handles; TikTok’s own search is the way to look people up by display name.

How long does a TikTok username have to be?

Between 2 and 24 characters, using only letters, numbers, underscores and periods.

Can a TikTok username end with a period?

No. Periods are allowed, but TikTok does not accept one at the end of a username.

Why can't I change my TikTok username again?

TikTok allows one username change every 30 days. The app shows when you will be able to edit it again.
