IDs for Webinars and Meetings

A meeting ID is a number that identifies a meeting, whether it is an instant meeting or one that has been scheduled. A meeting ID is usually 10 or 11 digits in length. Meetings can be instant, scheduled, or recurring by using the 11-digit meeting number. For personal meeting IDs, you will use a 10-digit number. For meetings that are scheduled prior to April 12, 2020, the meeting number may have 9 digits.

Expiration rules for meeting IDs

In general

  • are that the instant meeting IDs expire once the instant meeting has ended.
  • Once you have scheduled a meeting, you are able to start that meeting anytime.
  • You cannot start a meeting if it does not appear in the list of meetings that are coming up or those that have already occurred in your portal.

Non-recurring scheduled meetings can be started only once.

  • In order to keep the meeting ID (also known as one-time meeting ID) active, it must be scheduled, non-recurring, and it must expire 30 days after it is scheduled. The meeting ID will remain valid for another 30 days if you restart the same meeting within those 30 days.
  • There is no rule that prohibits starting scheduled meetings earlier than the scheduled time as long as the meeting ID has not expired or been deleted.

Recurring meetings

  • When you do not start a recurring meeting occurrence for a period of 365 days, then your recurring meeting ID expires.
  • By resetting the 365 day timer, you will be able to re-use the meeting ID for future meetings.


Note: Whenever scheduling meetings through the Outlook or Google Calendar integration, especially recurring meetings, please check the Zoom web portal for the most accurate information on the scheduled date and time.


  • We delete webinars 90 days after the scheduled end time or the time when the last modification was made.

Personal Meeting ID (PMI)

  • If you do not start a Personal Meeting ID (PMI), it will also expire in 365 days, since it is essentially a recurring meeting that does not have a fixed time.
  • After you have deleted your Profile page or Personal Room settings page, a new PMI will automatically be assigned to you once you revisit these pages.

Expired or deleted meetings

  • When you are trying to start your meeting, you will most likely see an invalid meeting ID message. This is because the meeting ID has expired or has been removed. Ensure that the meeting ID shows up on the meetings page in the Zoom web portal in the role of the meeting host.
  • Deleted meetings can be recovered for one week after they have been deleted. In the case of a meeting recovery, invitations, links, and meeting IDs sent before the meeting was deleted will still work.
  • Recovering permanently deleted meetings from the trash can is not possible.
