How to pre-assigning participants to breakout Zoom rooms

Organizers have the option to pre-arrange meeting attendees into breakout rooms when scheduling a meeting when converting the meeting to an open format. You may find this useful if you are already aware of the way your participants will be grouped.

The meetings can also be managed by managing your breakout rooms while they are in use.

Prerequisites for pre-assigning participants

  • There is a pre-assignment option available for breakout rooms with breakout sessions
  • turned off When the meeting is in place, ends-to-end encryption will be enabled
  • Host:
    • Zoom desktop client
      • For Windows: version 5.3.0 or higher
      • For macOS: version 5.3.0 or higher
      • For Linux: version 5.3.0 or higher
    • Web client
  • Participants:
    • Zoom desktop client
      • For Windows: version 5.3.0 or higher
      • For macOS: version 5.3.0 or higher
      • For Linux: version 5.3.0 or higher
    • Zoom mobile app
      • For Android: version 5.3.0 or higher
      • For iOS: version 5.3.0 or higher
    • Web client
    •  It is necessary for participants who join a meeting that has pre-assignments to be signed into the Zoom account associated with the email address used to create pre-assignments so that the pre-assignments can be applied. The pre-assignment won’t be applied to them if they are not logged in or if they are not logged in with the same account they used to sign in.


  • The company can pre-assign rooms for up to 50 participants and 200 rooms for up to 200 attendees. Using Breakout Rooms 100, if you have enabled this feature on your account, you can pre-assign as many rooms and participants as you wish.
  • Pre-assignments can be configured for meetings but only one set of pre-assignments can be added. There is the option of altering and changing pre-assignments but unfortunately it is impossible to store more than one set for one meeting or meeting series.
  • Pre-assigning participants will only work if they have an internal or external Zoom account (internal or external users of Zoom).
  • In order to assign external participants in a meeting who are not Zoom users, you can import a CSV file.
  • In order to allow your account’s breakout rooms to grow up to a maximum capacity of 100 breakout rooms, with a capacity of 1,000 per breakout room (depending on the account limits), Zoom Support can increase the capacity. If all or even most participants are participating in a meeting hosted by your account who do not have Zoom client version 5.2 or higher, they will be required to update their Zoom client before joining the meeting. They can also join with the web client if they have it. In the event that your users do not have access to their computers, updating the client on their computers would require that your IT Department assist you with this task.
  • You should make sure that you apply the predetermined breakout rooms to all meetings in a recurring meeting if you scheduled recurring meetings. In order to apply a unique pre-assignment to every meeting in a recurrence, you cannot edit the individual meetings in the recurrence.
