Paste any video, @handle, or channel link — get the underlying UC… channel ID
Every YouTube channel has a permanent internal ID starting with UC, separate from its display name and its @handle — which can both change. This tool works out that stable ID from almost any link: a video's watch page, an @handle URL, a legacy /c/ or /user/ vanity URL, or a /channel/UC… link you want to confirm. That ID is what many other tools and integrations actually need behind the scenes, since handles and custom URLs aren't guaranteed to stay the same.
@handle page, or a /channel/, /c/ or /user/ URL./channel/UC… page.Tips: a video link works just as well as a channel link — the video's page also carries its channel's ID, so you don't need to hunt down the channel's own URL first.
The channel ID (UC…) is a permanent internal identifier that never changes for the life of the channel. A handle (@name) and a legacy custom URL (/c/name or /user/name) are both changeable, human-readable aliases that YouTube maps back to that same underlying ID.
Yes — a video's watch page embeds its channel's ID directly, so pasting any video from a channel resolves to that channel's ID just as reliably as pasting the channel's own link.
This depends on YouTube's current public page markup, which can occasionally change or render differently for certain channels. If a lookup fails, try pasting a specific video URL from that channel instead of the channel's own page.
Whenever it can be confidently extracted, yes. If the page doesn't expose it clearly, the tool still shows the resolved channel ID and simply omits the name rather than guessing.
