What is a YouTube subscribe link?
It's your normal channel link with ?sub_confirmation=1 on the end. When a signed-in viewer opens it, YouTube shows a box asking them to confirm the subscription, instead of leaving them to find the button.
Removing that one step helps most on phones, where the Subscribe button is easy to scroll past. Use it anywhere you're already asking people to subscribe.
Handle, channel ID or custom URL?
A channel can have several addresses, and any of them can carry sub_confirmation=1:
- Handle: youtube.com/@yourname. The easiest to read and remember, but if you change your handle, links with the old one can stop working.
- Channel ID: youtube.com/channel/UC followed by 22 characters. It never changes, so it's the safest choice for anything printed.
- Custom URL: youtube.com/c/yourname. Older channels may still have one.
- Username URL: youtube.com/user/yourname. From YouTube's early days; it still works for some older channels.
Where to find your channel ID
On YouTube, open your profile picture, then Settings, then Advanced settings. Your channel ID is listed there with a copy button. It starts with UC and is 24 characters long.
Your handle is easier to find: it's under your channel name on your channel page, starting with @.
Where to use your subscribe link
Swap it in wherever you already link to your channel: your link-in-bio page, video descriptions, pinned comments, email signature, newsletter and other social profiles.
On print, like merch tags, business cards or event posters, use the QR code so people can subscribe straight from their phone camera.
Frequently asked questions
What does sub_confirmation=1 do?
It tells YouTube to show a subscribe confirmation box when the channel page opens. The viewer still taps to confirm, so nobody is subscribed without choosing to.
Why don't I see the subscribe box?
You need to be signed in and not already subscribed, and it won't show on your own channel. Test it from a different account.
Does it work in the YouTube app?
It works in browsers. When the link opens in the YouTube app instead, the box may not appear, so test it on your own phone.
Can I add it to a video link?
No. sub_confirmation=1 works on channel links, not video links, so link to your channel instead.
