A YouTube Channel ID is a unique identifier assigned to every YouTube channel. It always starts with "UC" followed by 22 characters (e.g. UCxxxxxxxxxxxxxxxxxxxxxx). It's used by the YouTube Data API, analytics platforms, and third-party tools to identify channels.
YouTube allows channels to set custom URLs (like youtube.com/@username or youtube.com/c/Name) that can change over time. The Channel ID (UCxxxxxx) never changes, making it the reliable permanent identifier for API calls and integrations.
Our server fetches the YouTube page for the URL you provide and extracts the Channel ID from the page source. This works server-side, so there are no CORS restrictions and it supports all URL formats.
Yes. Paste any YouTube video URL (youtube.com/watch?v=... or youtu.be/...) and the tool will find the Channel ID of the channel that uploaded that video.
The subscribe URL (with ?sub_confirmation=1) opens a YouTube page that prompts the visitor to subscribe to the channel. You can use it in call-to-action buttons, emails, and social posts to grow your subscribers.
Every YouTube channel has a public RSS feed at feeds.google.com/feeds/videos.xml?channel_id=... that lists all public videos. Use it with RSS readers, news aggregators, IFTTT, or Zapier to get notified of new uploads.
Yes. You can paste a full URL like youtube.com/@MrBeast or just the bare handle like @MrBeast. The tool will normalize it and find the correct Channel ID.
Some channels restrict access or YouTube may occasionally serve different page structures. If a lookup fails, try using the full channel URL (youtube.com/channel/ID) instead — if you already have the ID, it will be returned immediately without a network request.
There is no hard limit — the tool is free and unlimited. However, rapid sequential lookups may be slowed down by YouTube's own response times.
Common uses: YouTube Data API v3 (channels.list, search.list), Google Analytics channel tracking, social media scheduling tools (Buffer, Hootsuite), YouTube embed parameters, RSS feed subscriptions, and affiliate/sponsorship platforms that require a channel identifier.
