Prerequisites for requesting a number port

How to request a number port

  1. Download and complete the required Letter of Authorization (LOA)from the respective country.
    • See the porting guides if you need help.
    • If you currently have trial/temporary numbers and would like to swap them when the port completes, please complete the Number Swap Sheet. Numbers swapped in will be a like-for-like replacement of the numbers swapped out.
  2. Submit your order Here and make sure to follow the steps below:
    • Please select your request type: Zoom Phone Number Porting
    • Your email address: Make sure the email address is accurate
    • Type of issue: New Number Port
    • Porting Country: (Select Australia, New Zealand, Singapore, or Hong Kong)
    • Porting Number Quantity: (Select the range of quantity of numbers to port)
    • Subject: (Keep as it is)
    • Description: (Please make sure the details below are present for a smooth transaction)
      • Zoom Phone Account Number
      • Additional details and instructions
        • Add a note if the order is for BYOC number port
    • Attachments:
      • Completed and signed LOA (hand-signed or digital signature)
      • Recent telephone bill relating to your porting numbers (should be dated within the last 30 days).
      • Any other additional requirements applicable to the desired country.
  3. Zoom will review and confirm receipt of the request and will provide update as order progresses.
  4. Zoom will send a request to your service provider to validate the information on the LOA, as the transfer request is also dependent on your service provider.
    Your request will either be approved or rejected:
    • Rejected: If rejected, Zoom will inform you that your porting request was unsuccessful.  Rejection can occur due to a variety of reasons. The zoom porting team will provide you with the cause and how to resolve the rejection (which may require you to contact your current carrier to resolve the issue).
      Note: This may add an undetermined amount of time to your porting request
    • Approved: If approved, Zoom will inform you that your porting order has been approved with a date for when your number will be transferred to Zoom, and the numbers will be available on or before the day of port for you to manage in the Zoom web portal

General guidelines

  • The information you provide must match what is on record with your current provider.
  • In most APAC countries, the address noted on the LOA must match the geographic area code of the porting telephone numbers.
  • Porting numbers need to be in the LOA rather than as attachments unless otherwise permitted.
  • DDI blocks of numbers may require full port as some countries do not allow blocks/ranges of numbers to be split. Refer to our FAQ page for more information.
  • Number portability checks can only be carried out once the order is submitted. There may be times when providers advise that numbers as non-portable.
  • You may experience some loss of service to incoming calls during the port activation window while the porting numbers are in progress.
  • APAC Porting usually takes months to complete from the day of submission. See time frames for more information.

Additional requirements

Singapore

  • Only Fixed Line Numbers (+656xx) are portable as per a general rule.
  • Signed and stamped LOA must be correctly filled (matching donor’s records) and dated within the last 35 working days including the date you submit the porting request.
  • If a company stamp is unavailable, provide a company letter with company letterhead explaining why the company stamp is not available.
  • File a copy of ARCA Business Registration Certificate is required and must be included when requesting a number port.
  • Note: Unique Entity Number (UEN) or Business Registration Number (BRN) is a 9- or 10-digit identification number that the government issues in Singapore to all entities that operate within the country and must be included when filling out the LOA.
  • Partial porting (not porting all your numbers) may be supported but this depends on the agreement between your service provider and yourself, which needs to be arranged before the porting is requested. Because of the local regulations and the way numbers are allocated, porting is rarely supported.
  • A target port date when submitting your port request and must be between 35-40 business days from the day you submitted the order.
  • Note: Your provider will inform you about the port-out activity and will require your approval to proceed.
  • We can easily cancel or re-schedule your port request up until the time when the port date has been scheduled. Once a port date has been scheduled, cancellation or re-scheduling of port becomes more complex and riskier because the service providers involved may have already begun configuring your phone number. The further we are in the process when you decide to cancel or re-schedule, the less likely it is that we will be able to cancel successfully or re-schedule or re-schedule the port.
  • Please let us know at least (5) five working days prior to the scheduled day if you wish to cancel or re-schedule an already accepted port order. Note: This will be a best effort basis only.

Australia

  • Numbers can be ported in blocks or split up. If your current provider informs us that numbers are in blocks and need to port as such, but you do not want to keep them or add additional licenses for them, let us know five working days before or after the port completes which numbers you would like to keep. The remaining numbers will be returned to the provider and can no longer be retrieved once executed.

Hong Kong

  • File copy of Hong Kong Business Registration  Certificate is required and must be included when requesting a number port.
  • Notes:
    • Business Registration Number must be included when filling our the LOA.
    • Signature in the LOA should not be more than 30 calendar day old.
  • Partial porting (not porting all your numbers) is not supported.
  • We can easily cancel or re-schedule your port request up until the time when the port date has been scheduled. Once a port date has been scheduled, cancellation or re-scheduling of port becomes more complex and riskier because the service providers involved may have already begun configuring your phone number. The further we are in the process when you decide to cancel or re-schedule, the less likely it is that we will be able to cancel successfully or re-schedule the port.
  • Please let us know at least three (3) working days prior to the scheduled day if you wish to cancel or re-schedule an already accepted port order. Note: This will be a best effort basis only.
