YouTube Channel ID Finder
YouTube APIs, embeds and many tools need a channel's ID (it starts with UC), not its @handle. Enter a channel to look it up.
Finding it manually
Open the channel page, then view the page source and search for "externalId" or channel/UC. The 24-character value that starts with UC is the channel ID. This tool does the same lookup for you.
Accepted formats
@handle, youtube.com/@handle, youtube.com/c/name, youtube.com/user/name, or a youtube.com/channel/UC… link.
