Business Phone Number Porting Requirements

While the requirements to transfer phone numbers may differ between countries, in most cases you will need some combination of the following to start a VoIP number port: 

Letter of Authorization: This allows a new carrier to reach out to your current provider and start the number porting process for you. AVOXI provides this for anyone interested in transferring a business number to our network.


Proof of Ownership: Providing proof of ownership is as simple as sending a PDF copy of an invoice that associates your number, name, and billing address.


Number Porting Form: An additional form may be required to port international number. This is not required to port US or Canadian phone numbers.

Common Questions About VoIP Number Transfers

Backed by 20 years of experience providing international VoIP services, nobody but AVOXI makes business phone number porting so easy in 100+ countries. 

How long does it take to port a phone number?

The time required to complete a VoIP number transfer varies due to differences in the regulating bodies between countries and bottlenecks caused by the originating carrier. In most cases, international number ports to AVOXI are completed in: 

  • US and Canada toll free porting: 1-2 weeks
  • US and Canada local number porting: 2-3 weeks
  • International number porting: 3-4 weeks

What will it cost to port a business phone number?

If you'd like to port a business phone number to AVOXI, your total costs depend on your other carrier, as they may have a fee for porting numbers out in your contract. If they do not charge to port numbers out of their network, then porting your phone numbers is free! In fact, AVOXI will credit your account so you don't even pay for your first month of calls with on our network. 

How can I prevent delays while transferring business phone numbers?

There are a couple of steps you can take to ensure there are no delays during your VoIP number transfer:

  1. Make sure all of the details on your LOA are correct. Simple mistakes on this form can potentially cause your port request to be rejected.
  2. Do not discontinue your original service before porting is completed. If you do, you risk having your number released and losing it forever.

How can I avoid service interruptions while transferring a business phone number?

Businesses can’t just disconnect their number for a month without significant losses. To help avoid service interruption, you can set up call forwarding to a temporary line from your new provider. Now, any calls made to your primary business number will be automatically forwarded to your temporary line.

Can I port landline numbers to VoIP?

Yes, there is no special process or procedure required to do port landline numbers to VoIP. AVOXI will transfer landlines to VoIP numbers for free, and even pay you for porting!

What else should I consider when requesting a VoIP number transfer?

Before beginning the porting process, make sure you have reviewed the terms with your existing service provider. If you are in a contract, there may be early termination fees. Also, be sure that your account is in good standing before starting to port. If you have an outstanding balance, your previous provider may choose to terminate your service and release your number before the port is completed.  Finally, be sure to check if your business number is portable. In rare instances, a number may not be eligible for porting.

Can customers still reach me during the number porting process?

Yes, if you follow the steps outlined above, your business numbers should remain active throughout the process. For an extra layer of security, you can set up a temporary VoIP number with AVOXI and forward calls made to your original number until the porting process is complete. 

What else can AVOXI do for my business?

In addition to the best international number porting services anywhere, AVOXI is known for providing business phone numbers around the world and flexible, affordable contact center software.
