Twitch Username Checker
Validate name ideas against Twitch's format rules in bulk, then look up the valid ones on Twitch.
Twitch usernames must be 4-25 characters using letters, numbers and underscores only, and cannot start with an underscore. This checker validates the format of up to 50 names at once; it does not query Twitch, so use the link next to each valid name to see whether it is taken.

Twitch rules used: 4 to 25 characters, letters, numbers and underscores only, and the name cannot start with an underscore. This checks format only. It does not know whether a name is taken, banned or reserved: use the link next to each name to look it up on twitch.tv.
How to use the Twitch username checker
- Paste name ideas, one per line.
- Read which names pass the format rules and why others fail.
- Click “Look up on Twitch” for valid names: a profile page means the name is taken.
- Pick a name that also works on Kick and social platforms.
Why we do not claim availability
Live availability needs Twitch’s own systems; reserved, banned and recently changed names can look free but still be blocked. A format check plus a manual look-up is the honest way to shortlist.
