Requesting a number port

  1. Download and complete the required Letter of Authorisation (LOA) from the respective country. Download the porting guidelines if you need help
  2. Send an email to Make sure to include the following:
  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 EMEA countries.

  • In most European countries, the address noted on the LOA must match the geographic area code of the porting telephone numbers (excluding UK).
  • All porting numbers need to be noted on the body of the LOA rather than as attachments unless otherwise permitted.
  • DDI blocks of numbers may require porting in full as some countries do not allow blocks/ranges of numbers to be split. Refer to the common porting questions for more information.
  • 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. See lead times for more information.
