Requirements

• Pro, Business, Enterprise, or Education account
• Zoom Events Unlimited or Zoom Events Pay Per Attendee license
• Zoom desktop client for Windows, macOS, or Linux: Global minimum version or higher

Limitations for Zoom Events accounts

While access to Zoom Events is generally available worldwide, whether a user can register for and join an event, as well as the ability to host free and/or paid events, is determined by which country or region the user—host or attendee—is located in.

Learn more about geographic availability for Zoom Events and publishing available events in India.

Attendees

Before attendees join an event, they must register for all free and paid events. Access to Zoom Events, and whether attendees are able to register for a free or paid event, is determined by the country they are located in.

If enabled by the event organizer, users without a Zoom account can access and join a Zoom Event by using their email address.

Hosts

Similar to Zoom Webinars, you must have a Meetings license to purchase a Zoom Events license. Purchasing Zoom Events gets you everything you would get with a Zoom Webinars license, plus the added features.

Similar to Zoom Webinars capacity tiers, Zoom Events can support up to 100,000 attendees. Additionally, Production Studio and Simulive sessions support 100,000 attendees. For events with more than 10,000 people, contact sales.

During a Zoom Event:

• A limit of up to 500 sessions can be scheduled per event.
• A maximum number of 15 sessions being livestreamed to the lobby will appear in the event lobby, but only 5 will be shown in the lobby at a time. If more than 5 sessions are livestreaming to the lobby, attendees will be able to scroll and see each livestream.
  Note: Event organizers can configure lobby-livestream details such as rotation times, cover images, and custom image or video.

Support for 100,000 attendees

Notes:

• We do not support joining with the Linux client currently. Linux users should join through a web browser instead.
• We currently do not support hosts or panelists joining through the Android client at this time. It is recommended to use the Windows or macOS client. However, attendees can join with Android.

Zoom Events can support up to 100,000 attendees under these qualifications:

• The host and account must have the qualifying licenses:
  • For Zoom Events Unlimited license holders, the hub owner must hold a 50K Zoom Sessions/Zoom Events license, and the account must hold an additional 50K Zoom Sessions/Zoom Events license.
  • For the Pay Per Attendee (PPA) license holder, PPA seats count for each lobby visitor. An additional license is not needed. In both cases, the host must request the event to get the larger capacity.
   
• The host must request the higher limit via support for each specific event. The limit of self-serve remains at 50,000 attendees. Contact Zoom Support for more information.

Use best practices for 100,000 attendees

• With such a large audience, we do not recommend enabling Zoom Events chat for attendees.
• We recommend having a plan on how to answer session Q&A if you enable it.
• Ensure that you have updated to the latest version of the Zoom desktop client/mobile application.

Limitations for ticket capacity for Zoom Events

For free events, you can oversell tickets/registrations. Ticket capacity and registration capacity are not determined by your Zoom Events license—unless it's a paid event. 

The event ticket capacity depends on the number of attendees that your Zoom Events license allows. The maximum number of participants that your Zoom Meetings license allows has no effect on the event ticket capacity for your Zoom Events.

Limitations for event duration limit

Your meeting will automatically end based on the idle time, type of account, and the number of participants. These time limits apply to meetings and webinars regardless of the device used to start the meeting (client, app, or phone).

Limitations for event sessions

Lobby livestreamed sessions

Zoom Events can support all sessions that have opted to livestream to the lobby. There is no limit to the number of sessions to be livestreamed in the lobby concurrently. Loading latency may incur when more than 5 livestreamed concurrent sessions are configured.

Note: Expo livestreaming sessions do not stream to the lobby and are excluded from the number of concurrent livestreamed lobby sessions.

Limitations for scheduling Zoom Events with PayPal or Stripe

Zoom Event hosts can create and schedule paid events on any date.

For countries that support paid events, when you create a paid event and PayPal or Stripe is the online payment platform linked to your Zoom Events hub, your event’s paid ticket registration will be available for attendees 12 months before your paid event is scheduled to start.
