Frequently asked questions about meeting and webinar IDs
Meeting and webinar IDs are the numbers associated with an instant or scheduled meeting or webinar.
Meeting IDs are typically 10 or 11-digit numbers. The 10-digit number is used for personal meeting IDs (PMI), and the 11-digit number is used for instant, scheduled, or recurring meetings. Meetings scheduled prior to April 12, 2020 may be 9-digits long.
Frequently asked questions about Zoom meeting and webinar IDs
Where do I enter the meeting or webinar ID?
You can enter the meeting/webinar ID and passcode when joining a session from a web browser, desktop app, or mobile app. To quickly join and enter the meeting or webinar ID and passcode, you can launch the Join Meeting page, then choose if you want to open the app or stay in a browser.
Additionally, if you have the invitation link, the ID is embedded into the link so that you don't have to manually enter the meeting or webinar ID.
How can I change the meeting or webinar ID for a scheduled event?
When scheduling a meeting, you can either generate an automatic meeting ID or use your personal meeting ID (PMI). Generated meeting IDs are automatically created and included in the meeting invitation, and can't be changed. You can change your personal meeting ID on the Profile page in the Zoom web portal. If you schedule a meeting with your PMI, then change your PMI, the scheduled meeting will also have the new ID. Learn more about customizing your personal meeting ID.
Webinar IDs are generated automatically and can't be changed.
How can I troubleshoot an invalid meeting ID error?
If you are the meeting host and you see an invalid meeting ID message when trying to start your meeting, it is likely that the meeting ID has expired or was deleted. As the host of the meeting, check if the meeting ID appears on your list of Meetings in the Zoom web portal. If the meeting doesn’t appear in your upcoming or previous meeting list in the web portal, it can't be started.
Meeting ID expiration rules depend on the type of meeting.
Instant meetings
Instant meetings start immediately and allow participants to join at any time. An instant meeting ID expires when the instant meeting ends.
Scheduled, non-recurring meetings
A scheduled, non-recurring meeting ID (also known as a one-time meeting ID) will expire 30 days after the scheduled date. If you restart the same meeting ID within the 30 days, it will remain valid for another 30 days.
Scheduled meetings can be started at any time before the scheduled time as long as the meeting ID is not expired or deleted.
Recurring meetings
A recurring meeting ID expires if you haven't started a meeting occurrence for 365 days.
You can re-use the meeting ID for future occurrences, resetting the 365-day timer.
You can start your scheduled meetings at any time after you schedule them. Note: When scheduling meetings with the Outlook or Google Calendar integrations, especially recurring meetings, please refer to the Zoom web portal for the most accurate scheduled date/time information.
Personal meeting IDs (PMI)
Your personal meeting ID (PMI) will expire if you haven't used it for 365 days, as it is essentially a no-fixed time recurring meeting.
When viewing your Profile page or Personal Room settings page after it has been deleted, a new PMI will be automatically assigned to you.
What are the expiration rules for webinar IDs?
Webinar IDs will expire and be unusable past the webinar's scheduled end-time if the webinar is not currently in progress.
Non-recurring webinars are deleted 90 days after the scheduled end time or last modification.
A recurring webinar ID will expire 365 days after the webinar is started on the last occurrence. You can re-use the webinar ID for future occurrences.
How are meeting IDs handled for expired or deleted meetings?
For deleted meetings, you can recover a meeting up to one week after it was deleted. If you recover a meeting, invitations, links, and meeting IDs sent prior to deletion will still work.
Meetings permanently deleted from the trash can cannot be recovered.
