Requesting a number port

  3. Zoom will review and confirm receipt of the request.
  4. Zoom will send a request to your losing provider to validate the information on the LOA as the transfer request is dependent on your losing provider. If accepted, Zoom and the losing provider will work together to schedule the number port. Once approved, the numbers will be available for you to manage in the Zoom web portal.


  • The information you provide must match exactly what’s on record with your current provider.
  • LOA must be hand/wet signed and dated within the last 3 months. Electronically signed LOAs are not accepted in most LATAM countries.
  • The losing provider's name is required on the LOA.
  • Number portability checks can only be carried out once the order is submitted. There may be times where losing providers advise that numbers as non-portable.
  • You may experience some loss of service to incoming calls during the port activation window whilst the porting numbers are being transferred away from the losing provider.
  • Porting usually takes an average of 30 days from the day of submission.
