Zoom dial-in numbers

Zoom has toll numbers available for many countries that are included with all plans. For audio plan subscribers, Zoom also has toll-free and additional toll numbers available. The dial-in numbers available are dependent on the host's audio subscription and settings.

If the meeting invite does not provide a local number for your country, there is a more extensive list of Zoom international dial-in numbers. If a number is not listed, this means that it is not available on the account that you're currently signed in with.

If you have a Zoom Phone license, you can dial in to a meeting or webinar using Zoom Phone without incurring usage charges.

How to join a meeting or webinar by phone only

Join as a host

You can join and start any Zoom meeting from your telephone and control the meeting with DTMF tones.

  2. Enter the meeting ID followed by #.
  3. To be recognized as the host, enter your host key, which you can find on your user profile, followed by #.
    Note: If you enable join before host and join only from your telephone, you will not be recognized as the host and will not have host controls. If you need to host meetings from your phone with full host controls, do not enable join before host.
