Opting out of Zoom Phone SMS

If you want to integrate your existing SMS provider with Zoom Phone, you can do so.


The onus of sending future SMS inquiries to the relevant third party will be on you when you opt out of Zoom’s hosted SMS service. Zoom SMS will no longer be able to assist you with SMS troubleshooting if you opt out of the Zoom SMS service after you opt out of the service.

Prerequisites for opting out of Zoom Phone SMS

  • Ownership or administrative privileges on an account
  • That is licensed to use Zoom Phone

How to opt out of Zoom Phone SMS

  1. The following information should be sent to numberporting@zoom.us;
    • Subject line:
    • Switch to a third-party SMS provider
    • If you want to enable any phone numbers
    • Associated with your SMS provider’s NNID (Net Number ID). If you do not have this, you will need to contact Zoom before opening a ticket.

    • Be sure to include the following text:
