Zoom will schedule the number porting with the losing provider if it is approved. In the Zoom web portal, you will be able to manage the numbers once they are approved.


  • Your information must exactly match what your current provider has on file, so make sure to do that.

  • Prior to the port being submitted to the losing carrier, a number of portability checks will be carried out.
