Check if a YouTube username is taken

What we check on YouTube

Instant tier for username lookups - answered in well under a second

YouTube is checked from a username. The response says whether that handle exists on YouTube - registered: true or registered: false - with the moment that was established in checkedAt. An email address on its own cannot reach YouTube; if you only have an email, its local part is tried as a handle and any hit is labelled as derived, never counted as a confirmed match.

YouTube is in the instant tier: with ?instant=true it is among the first platforms answered, in well under a second. On a full lookup it is checked alongside every other platform and streamed as it lands.

If YouTube blocks the check, times out, or answers ambiguously, it is omitted from results[] entirely rather than returned as registered: false. Absence from the response means "unconfirmed", never "no account".

Who checks YouTube accounts

Media and publishing accounts are checked because listening, reading and blogging histories are among the oldest footprints a real person leaves. An email that has streamed music or published posts for years behaves like a real customer; one with no media history at all is more often a fresh, single-purpose address.

Inputs YouTube accepts

• Username: send the handle as query. YouTube is checked for that exact handle - useful when a person reuses the same name across platforms.

What a YouTube result looks like

  "platform": "youtube",
  "registered": true,
  "checkedAt": "2026-10-15T09:53:15.439Z",
  "identity": "username"
}

The full response shape - breaches, web mentions, matches versus socialMatches, and what method means - is in running a lookup.

YouTube lookup FAQ

Can I check a phone number on YouTube?

Not directly. YouTube can be reached from username. Phone numbers are checked on the messaging and social apps that sign people up by phone.

How fast is a YouTube check?

Fast: YouTube is in the instant tier, so with ?instant=true it is answered in well under a second. A full lookup streams it as soon as it lands.

What happens if YouTube blocks the check?

YouTube is left out of the response. We never report a platform we could not confirm as "not registered" - a missing platform means unconfirmed, not absent.

Does the API return the YouTube account details?

No. You get whether an account exists for the input you sent, and when that was established. No profile contents, photos, followers or private data are collected or returned.
