Telephone Number Porting

Modified on Fri, 24 Nov 2023 at 02:19 PM

This post shows how to port your telephone number to RingOffice. RingOffice offers number porting or LNP (Local Number Portability) throughout Canada, the United States, and several other countries. This means you don’t have to worry about losing your number when you switch to RingOffice as your service provider or if in the future you choose to switch to any other company as your service provider.

Whether you have one or many phone numbers to transfer, the porting process generally takes between 5 to 10 business days depending on rate centre, carrier and order complexity. There is also usually a one-time fee for processing LNP orders.

Since we depend on the releasing carrier’s cooperation for transfers, there is always a risk of delay or disruption. RingOffice takes the following measures to minimize disruption and deliver a smooth transition:

  • Careful pre-submission port order vetting to avoid rejections and delays.
  • Temporary number assignments to facilitate number call redirection during order processing
  • Flexible scheduling to accommodate your preferred porting date.
  • Regular progress updates when order status changes to keep you informed.
  • Advance number pre-configuration in our switching system for a smooth transition.
  • We can help you pre-configure numbers in your phone system for seamless call flow once your transfer is complete.

Once your porting order has been accepted, RingOffice will notify you of your confirmed porting date. On the porting date, once you have tested and confirmed your number porting is complete, you can notify your previous service provider to stop billing you for the ported number(s).

Here’s what RingOffice needs to port phone numbers:

  • For Local numbers, we need a completed and signed Letter of Authorization form: RO Local LOA. Multiple numbers (if on the same account with the same service address) can be listed on the same LNP LOA form. LOA form should contain
          a) List of Numbers to be ported. 
          b) List of numbers to Be disconnected.
          c) List of numbers to remain active with your current provider.
  • If you are porting any Toll-Free numbers, we also need a completed and signed Letter of Authorization form: RO Toll Free LOA. Multiple toll-free numbers (if on the same account) can be listed on the same TF LOA form. The name and signature on this form should be the authorized contact in the current provider’s records.
  • A recent bill copy showing the Telephone Numbers, Account Name and Service Address (should be complete with all pages)
  • If Service Address is different from the billing address, we need to know the service address listed with the current carrier.
  • If the bill copy does not show any of the requested information, please provide us the “Service and Equipment records”. This is an official document issued by all telephone service providers and can be acquired by a simple request.
  • If you are porting mobile numbers, then we will need your Account number with your wireless carrier. Also make sure to reply to the text message confirmation from your wireless carrier within 90 minutes to ensure that your transfer is not rejected.
  • If you are porting numbers that are currently on a PRI (or Megalink), then we will need the Circuit ID, the pilot number and a full list of all numbers on the PRI with clear instructions for each.
  • If there are services on the same bill that are dependent on the number being ported but you do not wish for these services to be cancelled, you must contact your existing carrier to have them separated onto a new billing account (e.g. your DSL Internet relies on your main phone line instead of a dry loop). Contact us for help with this.
  • We recommend confirming contractual/billing obligations for the numbers being ported with your current service provider prior to number porting.
