What is an unlisted video?
An unlisted video is a different type of private video. "Unlisted" means that only people who know the link to the video can view it (such as friends or family to whom you send the link). An unlisted video will not appear in any of YouTube's public spaces (such as search results, your channel, or the Browse page). An unlisted video is different to a private video in these ways:
* you don't need a YouTube account to watch the video (you can see an unlisted video if someone sends you the video's link) * there's no 25 person sharing limit
Even though your video will not appear in any of YouTube's public spaces, links to the video could still appear elsewhere on the web if anyone who knows the video's URL shares it. It is therefore up to you to maintain the privacy of your video and the unlisted URL. You can further restrict the video at any time by returning to your account and marking the video as Private.
