Request Zoom Webinar Access or Change Zoom Webinar Participant Limit


Webinar options are not available in Zoom without webinar access. How do you get access?


Zoom provides students, faculty, and staff with the ability to message and chat with each other through videotelephony and online chat services through a cloud-based peer-to-peer software platform


Request Webinar access in Zoom by filling out the form below:

Webinar licenses are granted automatically and instantaneously, if you indicate in the form that you need one.

Webinar Participant Limits

Zoom Meetings can accommodate up to 300 participants. For more than 300 participants, you will need a Zoom Webinar license. If you are holding events with fewer than 300 participants but you would still like a webinar license, you may request one. U-M has 2 types of standard Zoom Webinar licenses, both of which can be requested through the webinar form (same as the one linked above):

  • Webinar 500, which can accommodate up to 500 participants
  • Webinar 1000, which can accommodate up to 1000 participants

You can change whether you have a Webinar 500 or a Webinar 1000 by completing the same form again. The license you have will be whichever you most recently requested, so if you requested a 500 and then changed your mind and completed the form again to request a 1000, you will now have a 1000.

Licenses for more than 1000 participants are extremely limited, checked out for no more than 1 week at a time, and require a minimum of 7 business days processing time. Fewer than 5% of Zoom Webinars even go over 500 people, and fewer than 2% go over 1000--it is very rare that these larger licenses will be needed. Licenses for more than 1000 participants are added on top of an existing webinar license to temporarily increase the capacity of your webinars for the given time frame, so they are ONLY needed at the exact time of the event--the webinar MUST be set up ahead of time before requesting the larger license. If you think you need a license for more than 1000 participants, create your webinar FIRST, then complete this form.
