Requesting a number port

  1. Fill in the required Customer Instruction Form and ensure you paste it onto the business letterhead of your company, and then be sure to print out the form.
  2. You can reach us at by sending an email that includes the following information:
    • Please send your email with the subject line “South Africa number port”.
    • A Customer Instruction Form filled out and signed by the customer.
    • Your recent telephone bill for the porting of numbers, which should be dated within the last 30 days, should include this information.
  3. Zoom will review the request and confirm it has been received.
  4. ZOOM will make sure the porting number can be transferred by contacting our local partner in South Africa. The porting Letter of Authorization (LOA) will be sent to you once the numbers are confirmed as transferrable.
  5. Since the transfer request is dependent on your losing provider, Zoom will ask them to validate the information in your LOA. 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.
  • It is important to have a signature and a date on the Letter of Authorization within the past three months. South Africa does not recognize electronic signatures on letters of authorization.
  • Prior to the port being submitted to the losing carrier, a number of portability checks will be carried out.
  • The individual who signs the Letter of Authorization and requests the port must have the authority to change any aspect of the account with the losing supplier.

There may be times when the providers suggest certain numbers are not transferrable.

  • While the numbers you are porting away from the losing provider will be transferred away, you may experience some loss of service to incoming calls during the activation period.
  • It usually takes 45 days on average from the day the LOA is submitted for the porting to take place.
