From July 15, 2022, Zoom will have a 40-minute limit even for meetings with two participants if you have a free subscription. (Previously, it was only for meetings with 3 or more people.)
Companies and organizations using Zoom for business should consider switching to a paid license at this opportunity. 

When you have a meeting with Zoom, you need something like a room number called “meeting ID”, and by telling the participants this ID, you can have a conversation in the same Zoom room.

Here, we explain how to issue a meeting ID necessary for holding a meeting on Zoom.

We also introduce how to host and participate in a meeting using a meeting ID, and cases where the ID becomes invalid, so please refer to it.

What is a Zoom meeting ID?

Zoom has a number called a meeting ID, and by sharing this number you will be able to host and participate in meetings.

First, let’s take a closer look at how to issue and confirm meeting IDs.

How to issue a meeting ID

There are two types of Zoom meeting IDs: “Instant Meeting ID” and “My Personal Meeting ID (PMI)”.

The “Instant Meeting ID” is used for Zoom meetings with default settings.

The Instant Meeting ID is an 11-digit number set for each room.

A new ID is automatically generated each time an instant meeting,  webinar page. Here you will see a list of scheduled meeting, or recurring meeting is created.

The instant meeting ID changes each time, so there’s no need to record it anywhere.

To find your meeting ID

If you want to check the meeting ID after the meeting has started, click the information mark at the top left of the screen.

The meeting ID will be displayed along with the host’s name and set up a password at the individual meeting, go to the settings tab and enable it. This setting will give you an option to set your password.

For scheduled meetings, you can check the ID from the meeting list screen.

For iPhone/iPad, you can check in the same way by tapping “Zoom ▽” at the top of the screen.

Difference from “My Personal Meeting ID”

In what cases is My Personal Meeting ID necessary?

My personal meeting is a dedicated ID assigned to each user and is automatically issued when a Zoom account is created.

Unlike the Instant Meeting ID, My Personal Meeting ID is always fixed with the same number.

This means that anyone who knows your personal meeting ID can join your meeting 24 hours a day.

If you let an unspecified number of people know your personal meeting ID, there is a possibility that troubles such as another user entering during the meeting may occur.

It is safer to use your personal meeting ID only for people who use Zoom regularly for work, and not to tell it unnecessarily.

Now that you understand the role of Zoom’s meeting ID, let’s check how to actually hold a meeting using the meeting ID.

Here, we will introduce how to hold and participate in a meeting using an instant meeting ID.

Hosting and Inviting Meetings

The procedure for holding an instant meeting and the invitation procedure is as follows.

  1. Launch the Zoom app
  2. Click “New Meeting”
  3. Click “Participants” from the toolbar at the bottom of the screen
  4. Tap “Invite”
  5. Notify the invitation URL by email or chat within Zoom

When joining a meeting

If you have been invited to a meeting, here’s how to join:

  1. Launch the Zoom app
  2. Click the invitation URL notified in the chat within Zoom
  3. Enter the notified password and click “Join”

If you are invited by email, you can join directly from the link in the email without launching the app.

There is also a method of joining by directly entering the instant meeting ID without using the invitation URL. It is convenient because you can easily teach each other when chat is turned off or when requesting temporary participation in a meeting via phone or another SNS.

Why and what to do if the meeting ID is displayed as invalid

When joining a meeting to which you have been invited, you may receive the message “This meeting ID is invalid. Please check and try again.”

We’ve put together the reasons why this happens and how to deal with it, so let’s check it out at the end.

Meeting ID has expired

The Instant Meeting ID has an expiration date, and there are cases where the ID becomes invalid after this expiration date.

The expiration date of the ID for each meeting is as follows.

Meeting type date of expiry
instant meeting as soon as the meeting ends
scheduled meeting 30 days after scheduled date or start
regular meetings 365 days after the start of the last meeting

Incorrect input of meeting ID

If you enter the meeting ID manually, you may not be able to participate due to input errors.

You can prevent mistakes by clicking the invitation URL or entering the meeting ID by copy and paste.

If you cannot enter the meeting even after entering it many times, it may be a transmission error on the host side, so please have the invitation email sent again.


  • There are two types of Meeting IDs: Instant Meeting ID and My Personal Meeting ID.
  • It is usually safer to use the Instant Meeting ID and limit the use of My Personal Meeting ID to specific parties.
  • If your meeting ID shows as invalid, it’s most likely due to an expired or mistyped meeting ID.

When introducing Zoom in a company, it is necessary to explain the difference between the two IDs properly and be careful not to spread My Personal Meeting ID to an unspecified number of people.

You can also change your personal meeting ID if you’re on a Zoom paid plan, so if you’re considering introducing it to your company, be sure to check out the paid plans as well.
