Twitch Username Checker
Type a name and this asks Twitch's own API whether any account holds that login, active, inactive or banned. Available means no account uses it right now, so you can sign up with it. Twitch logins are 4 to 25 characters of letters, numbers and underscores, and case does not matter: Ninja and ninja are the same name.
Free, no sign-in. Checks twitch.tv/name plus .tv, .gg, .com.
Twitch username rules
- 4 to 25 characters.
- Letters a to z, digits 0 to 9 and underscores. No spaces, hyphens or dots.
- Case is ignored: the login is stored in lowercase, only the display name keeps capitals.
A name that breaks these is reported as not allowed without asking Twitch.
What taken and available mean on Twitch
Banned and suspended channels count as taken
The checker asks Twitch for every account, not only active ones. A suspended channel shows no page, yet its name cannot be claimed, so it reads taken here. Measured: a suspended streamer's login comes back empty when Twitch is asked for active accounts and present when asked for all.
Opening twitch.tv/name proves nothing
Twitch serves the same page shell whether a channel exists or not. Measured on 2026-09-18: twitch.tv/ninja, one of the biggest channels on the site, returned the same 196,546-byte page as a name nobody has. That is why this asks the API instead of loading the page.
Available is a snapshot
Someone can take a name minutes after it shows available. Twitch settles it at signup.
The matching domain
Streamers put the name on overlays, merch and sponsor decks. A domain gives you a link you own for schedules and a link-in-bio page, which a Twitch URL cannot. .tv is the extension Twitch made famous, .gg is gaming's, and .com is what people type by default.
Twitch username questions
How do I check if a Twitch username is available?
Type it in the box at the top of this page. domhaul asks Twitch's own API whether any account, active or banned, holds that login and answers in about a second. You do not need a Twitch account or a domhaul sign-in.
What are the rules for a Twitch username?
4 to 25 characters, using only letters, numbers and underscores. No spaces, hyphens or dots. Case is ignored, so CoolName and coolname are the same login.
Why does a Twitch name show as taken when the channel page is empty?
Because a suspended, banned or inactive account still owns it. Twitch hides those channels but keeps the name, so it cannot be registered. Loading twitch.tv/name is not a reliable test: Twitch serves the same page shell either way.
Does checking a username reserve it?
No. Nothing is held for you: the name is yours only once you sign up with it or rename your account. Answers here are cached for up to 24 hours, so a name someone claims in between can still turn out taken at signup.
Should I register the matching domain for my Twitch name?
If you plan to stream under the name, yes. A name.tv or name.gg domain is a link you own for schedules, merch and sponsors, and it keeps working if you ever move platforms. The box above checks .tv, .gg and .com for the same name.
