YouTube Username Checker

It asks YouTube's own handle lookup for the name. If YouTube returns a channel, the handle is taken; if it returns nothing, no channel uses that handle. A second, key-less check then loads youtube.com/@name: if that page opens, the handle is reported as taken even when the API returned nothing.

It means no channel currently uses it. YouTube still applies its own rules when you claim a handle and can refuse reserved names, trademarks and names that impersonate someone, so the final answer always comes from YouTube Studio.

Up to 20 per request. Paste one per line, or separated by commas or spaces. Repeats are collapsed before anything is looked up, because handles are not case-sensitive, so @Name and @name are the same handle.

Three to 30 characters, made of letters, numbers, underscores, hyphens and periods. It cannot be only numbers, cannot look like a URL, and cannot start or end with a period or contain two in a row. Names that break a rule are marked invalid with the reason.

Because YouTube did not answer — usually the shared daily quota, a timeout or an invalid key. A name that could not be checked is never reported as available; it is marked as not checked so you can try it again.

When a single handle is taken, variations of it are built and each one is checked the same way. Only names that came back free are shown, so every suggestion has been verified rather than guessed.

No. Every tool is free and needs no account. Nothing you paste is stored: the request is processed and the result is sent back to your browser.

The shared YouTube Data API quota resets daily. If it runs out, open Advanced options and paste your own YouTube Data API v3 key; it is used for that one request and never saved.
