Restricted Mode is an optional setting that you can use on YouTube. This feature can help screen out potentially mature content that you or others using your devices may prefer not to view. Computers in libraries, universities, and other public institutions may have Restricted Mode turned on by a network administrator.

Channel URL (ID-based) Example: youtube.com/channel/UCUZHFZ9jIKrLroW8LcyJEQQ. This example is a standard URL that YouTube channels use. It uses your unique channel ID, which is the numbers and letters at the end of the URL.

If you need to change your URL, you can do this by updating your handle at youtube.com/handle. New custom URLs can no longer be set up and existing custom URLs can no longer be changed. Existing custom URLs will continue to work. If you must permanently delete your custom URL, you can do so by deleting your channel.
