Zoom Keep Same Meeting ID? How It Works

Yes, Zoom can keep the same meeting ID for your recurring meetings, and for Personal Meeting ID (PMI) meetings it always stays the same. You choose this when you schedule a meeting by enabling the Recurring meeting option, which lets you reuse one ID and link for every occurrence. This article explains exactly how to set that up, how the different ID types work, and what to watch out for.

Formula

The calculator works out how many times a recurring meeting happens in a year and the total hours spent in those meetings. The formulas are:

• Sessions per year = 365 ÷ recurrence interval (in days)
• Total time per year (hours) = sessions per year × meeting length (minutes) ÷ 60

Variables:

• t = meeting length in minutes (e.g., 60)
• d = number of days between recurrences (e.g., 7 for weekly)

The result assumes a full year with no skipped sessions (e.g., holidays or cancellations).

Worked Example

Using the default values: a 60-minute meeting that recurs every 7 days.

1. Step 1: 365 ÷ 7 = 52.14 sessions per year (rounded to 52 sessions)
2. Step 2: 52 × 60 minutes = 3,120 minutes per year
3. Step 3: 3,120 ÷ 60 = 52 hours per year

The calculator shows 52 sessions and 52.0 total hours per year.

What “Same Meeting ID� Means in Zoom

Zoom uses two types of meeting IDs: Personal Meeting ID (PMI) and auto-generated IDs. A PMI is a permanent, unique number assigned to your account. When you start an instant meeting with your PMI, the ID never changes. Auto-generated IDs are random numbers created for each scheduled meeting; they are unique to that meeting and cannot be reused unless you specifically set the meeting as recurring.

For scheduled meetings, Zoom gives you the option to make it a recurring meeting. When you do, the same meeting ID (and the same join link) is used for every occurrence of that series. This is the standard way to keep a stable ID for weekly team calls, classes, or webinars.

How to Set Up a Recurring Meeting with a Fixed ID

Here are the steps in the Zoom desktop app and web portal:

1. Sign in to the Zoom web portal (zoom.us) or open the Zoom desktop app.
2. Click Schedule a New Meeting.
3. Fill in the topic, date, and time for the first occurrence.
4. Check the box labeled Recurring meeting.
5. Choose the recurrence pattern: daily, weekly, monthly, or no fixed time.
6. Set the frequency (e.g., every 1 week) and the end date if needed.
7. Click Save. The meeting ID shown (usually a 9–11 digit number) will be the same for every occurrence.

Note: If you use your PMI as the meeting ID for the recurring meeting, it will also stay the same. You can select this under the “Meeting ID� section when scheduling.

PMI vs. Recurring Meeting ID: What’s the Difference?

Both give you a stable ID, but they work differently:

• PMI: Always the same number, even for instant meetings. If you share your PMI link, anyone can join any meeting you host with that ID (unless you set a passcode or waiting room).
• Recurring meeting ID: A fixed ID for a specific series. It is separate from your PMI unless you choose to use the PMI for that series. The ID is reused only for that series, not for other meetings.

If you want a permanent “virtual room� for one-on-one calls or a monthly board meeting, PMI is convenient. For a class that meets weekly, a recurring meeting ID is cleaner because you can set different settings (e.g., passcode, waiting room) per series.

Common Problems with Reusing a Meeting ID

Keeping the same ID is handy, but it can cause issues:

• Accidental joins: If someone has the old link, they can join any occurrence. This is more likely with PMI. Always use a passcode and enable the waiting room for sensitive meetings.
• Meeting ID confusion: If you have multiple recurring meetings with similar IDs, participants might join the wrong one. Double-check the ID when sharing.
• Zoom’s “reuse� limit: For free accounts, a recurring meeting can be reused indefinitely, but the meeting itself has a 40-minute limit for 3+ participants. After 40 minutes, the meeting ends, and you must restart it (same ID) – which is allowed.
• Security concerns: Reusing an ID makes it easier for “Zoombombing� if the ID becomes public. Always require a passcode and use the waiting room.

How to Change Your Meeting ID

If you need a new ID for an existing recurring meeting (e.g., the old one was compromised), you cannot edit the ID directly. Instead:

1. Delete the original meeting.
2. Schedule a new meeting (recurring if needed).
3. Share the new ID and link with participants.

For PMI, you can change your PMI in the Zoom web portal under Profile → Personal Meeting ID → Edit. You can choose a new PMI or reset it, but this will break any links that used the old PMI.

Costs and Account Types

Zoom’s free tier allows you to create recurring meetings with a fixed ID. The main limitation is the 40-minute limit on group meetings (3 or more participants). Paid plans (Pro, Business, etc.) remove that limit and add features like cloud recording and longer meetings. The ability to reuse a meeting ID is available on all plans, so you don’t need to pay just for that feature.

Alternatives to Zoom for Fixed Meeting IDs

Other video conferencing tools offer similar features:

• Google Meet: Generates a new link for each meeting, but you can create a “recurring� meeting in Google Calendar that uses the same Meet link.
• Microsoft Teams: Each team or channel has a permanent meeting link that you can reuse.
• Webex: Offers personal meeting rooms with a fixed URL, similar to Zoom’s PMI.

Each tool has its own naming and settings, but the concept of a “personal room� is common.

Frequently Asked Questions

Can I use the same meeting ID for two different meetings?

No. A meeting ID is tied to a specific scheduled meeting (or a recurring series). You cannot reuse the same ID for two separate series. If you try to schedule a second meeting with the same ID, Zoom will either block it or assign a new ID.

Does the meeting ID change if I edit a recurring meeting?

Editing the date, time, or other settings of a recurring meeting does not change the meeting ID. The ID stays the same as long as you do not delete the meeting and create a new one.

What happens to my recurring meeting ID after the series ends?

Once the series ends (e.g., the end date passes), the meeting ID is retired. You can still see it in your past meetings list, but you cannot start a new occurrence with that ID unless you edit the series to extend the end date.

Is it safe to share a recurring meeting link publicly?

It is not recommended. Because the link works for every occurrence, anyone with the link can join all future sessions. Use a passcode and enable the waiting room to control access. For public events, consider using a webinar or a unique meeting per session.

Why does my Zoom meeting ID change when I start an instant meeting?

Instant meetings use a random auto-generated ID by default. To use your PMI instead, go to your Zoom settings and enable “Use Personal Meeting ID (PMI) when scheduling a meeting� and also set “Use PMI for instant meetings� in the desktop app.

Can I set a custom meeting ID in Zoom?

No. Zoom does not allow users to type a custom ID. You can only use your PMI (which you can personalize once) or the auto-generated IDs. Changing your PMI is possible but limited to a few times per year.
