How Many Subscribers Do You Need to Go Live on YouTube?
You can start YouTube streaming with any number of subscribers if you are using a desktop computer. Subscriber number restrictions are only if you live stream on YouTube with a mobile phone or tablet.
If you plan to start YouTube streaming using your mobile device, you must have at least 50 subscribers. If you have under 1,000 subscribers, YouTube will limit the number of viewers and your stream will automatically be set to “Private.”
