VoIP number porting: How to switch your existing number to a new provider

VoIP number porting

When you’re making a move to a new phone system, customers will continue to call and text your business phone number — the one they’ve always contacted — and expect you to be at the other end of the line.

Luckily, VoIP number porting is a seamless process that keeps your business line running with zero disruptions. Here’s what you need to know about porting your phone number to a new VoIP provider.

What is VoIP number porting?

Port your VoIP number to OpenPhone

VoIP number porting lets you retain your existing phone number by moving fro your current phone provider (whether that’s a traditional carrier or a VoIP service provider) to a new VoIP service provider.

The Federal Communications Commission (FCC) requires telephone companies to comply with port requests as long as you’re within the same geographic region.

This way, you don’t have to deal with printing out new business cards or adding a new phone number to your website — you can still keep your existing phone number with a new VoIP service.

How exactly does phone number porting to a VoIP provider work?

The phone number porting process only takes a few steps, no matter what provider you’re switching from or which VoIP service you’re moving to. Here’s what it takes to port out your number to a new provider:

1. Let your current provider know you want to port out

Giving your current provider a heads-up that you’re porting out can help you avoid delays on either end of the porting process. Your current provider won’t have to do anything right away, but keep in mind that some providers may charge a porting fee or a termination fee, depending on the terms of your contract. For example, Google Voice’s free plan requires you to pay to unlock your number from their system before you can port your number from Google Voice

2. Send required information to your new provider

To comply with FCC regulations, your new provider will need your phone bill, latest invoice, and account number. Make sure your documentation includes your name, billing address, phone number, and PIN number (if you have one associated with your account).

You’ll also need to sign a Letter of Authorization so your new provider can port out your number.

Your provider may also request information about the phone numbers you’re porting, like if it’s a mobile, landline, or VoIP number. If you’re looking to port multiple numbers over to a new provider, you’ll also want to make that clear to the provider in any written communication to them. 

3. Maintain your current phone service until porting is complete

To avoid any service disruptions, wait until your port is complete before closing your current account. This way, you can continue making and receiving calls while your new provider works their magic. Your new carrier will let you know your port date, after which you can cancel your old service.

How long does VoIP number porting take?

VoIP number porting: Things to keep in mind

Several factors can affect how long it takes to port your phone number. Here’s what you need to know to avoid or anticipate delays in the porting process.

VoIP number porting requirements

The best way to keep your porting process as efficient as possible is to send your provider all the required documentation as soon as possible. For legal reasons, your provider will need to request the following documents and information:

  • A signed Letter of Authorization (LOA)
  • Your most recent phone bill
  • Your current provider, account number, and port-out PIN number
  • A list of the phone numbers you want to port

The name and phone number listed on your phone bill should match the information on your LOA.

Factors that can delay VoIP number porting

While the VoIP number porting process is usually straightforward, some factors can cause delays. If you’ve triple-checked the documentation you provided and are confident that it’s correct, here are a few common reasons porting may take longer than expected:

  • Your existing service provider is slow to respond to your new provider
  • You’re porting in a phone number from outside of the US
  • You’re moving a landline number to a new provider
  • Your porting request is rejected due to spelling errors, incorrect information supplied (such as the address or account number not matching what your current carrier has on file) and signatures from unauthorized sources
  • Your phone number requires complex porting, which may be the case if it’s attached to multiple lines or unique features like call forwarding and specialized call groups
Can I transfer a cell phone number to a VoIP system?

Yes, as long as the VoIP provider supports the area code or region of the phone number you’re wishing to transfer over, you should be able to port your cell phone number.

Can I port a VoIP number to a cell phone?

Porting a VoIP number to a cell phone is sometimes possible. However, if your VoIP phone number uses an area code that doesn’t match your geographic area — for instance, if you have a Canadian phone number but live in the United States — your cell phone service provider may require you to select a new number. This usually occurs if your new provider doesn’t have the local infrastructure in those areas.
You can typically check your number portability on your new carrier’s website, so you know if you can make the switch.

Can I port my phone number to a VoIP solution?

Yes, you can port your phone number to a VoIP provider in the majority of cases. Since VoIP solutions provide service over the internet instead of through local cell towers, they can support the porting of more telephone numbers than the average cell phone or landline carrier, regardless of your location. For example, you can port US, Canadian, and toll-free numbers to OpenPhone.

What phone numbers are unable to be ported?

Most personal and business phone numbers are portable. However, some landlines and international numbers may encounter porting issues due to information mismatches.
