Yes, you can keep your business phone numbers when switching VoIP providers. The process, called porting, allows you to transfer your existing numbers to your new VoIP provider so customers can continue reaching you without interruption.
There’s a classic song by Tommy Tutone with the unforgettable phone number 867-5309. In it, he pleads, "Jenny, don't change your number." It’s a catchy lyric, but also a reminder of how deeply attached we become to familiar phone numbers.
At TeleCloud, we understand how important your business identity is and that starts with your number. We've helped countless businesses retain their numbers while changing VoIP providers to get better service, pricing, and features.
In this guide, we’ll walk you through exactly how number porting works, what to expect when switching providers, and why choosing the right VoIP partner makes all the difference.
Can I keep my phone number if I switch to a VoIP provider?
Yes! Keeping your phone number when switching VoIP providers is not only possible, it’s highly recommended. Providers like TeleCloud make it easy to transition your current numbers from your existing provider. This process, called porting, ensures your customers can continue to reach you at the numbers they know.
How Does Porting Work?
Porting your number between VoIP providers is a straightforward process, but there are a few technical steps involved. Here’s how it works:
-
Gathering Information: To begin, you’ll need to provide your new VoIP provider with:
- A copy of your most recent phone bill.
- A list of the phone numbers you’d like to keep.
- A signed letter of authorization (LOA) giving permission to transfer the numbers.
-
Analyzing Your Bill: The provider will review your bill to identify:
- The total number of lines you have.
- What each line is used for (e.g., voice, fax, alarms).
- Any potential early termination fees with your current carrier.
-
Submitting the Port Request: Your provider will create a Line Number Portability (LNP) case, which includes all the required information, and sends it to your current carrier.
-
Timeline for Porting:
- Porting usually takes about 10 business days.
- You’ll receive two dates during the process:
- Temporary Order Commitment (TOC): Your current carrier acknowledges the port request.
- Firm Order Commitment (FOC): Your current carrier confirms the transfer date.
-
Final Transfer: On the agreed FOC date, your numbers will be ported to your new VoIP provider.
What Concerns Should You Have About Switching VoIP Providers?
Switching providers can feel risky, but the right partner makes it smooth and secure. If you're worried about losing service, losing your number, or facing hidden fees, here’s what you need to know:
-
Will I lose my number? No. Your existing number can be ported without disruption—as long as the correct documentation is submitted.
-
Will there be downtime? With a well-coordinated porting plan, downtime is minimal to none. Transfers happen during off-peak hours when needed.
-
What if something goes wrong? A provider like TeleCloud manages the entire transition and communicates directly with your current provider to avoid surprises.
-
Will the new system be difficult to use? Most modern VoIP systems are user-friendly and come with onboarding support and training.
-
Is switching worth it? If you're experiencing poor support, outdated tools, or overpaying for limited functionality, switching providers can improve performance, reliability, and cost-efficiency.
How to Make Porting Go Smoothly
Porting your number is a simple process, but there are ways to make it even smoother. Here’s how to ensure a successful and stress-free switch:
-
Double-check your billing info: Make sure your business name, service address, and numbers match what’s on file with your current provider.
-
Avoid scheduling conflicts: Try not to change or cancel your existing service during the porting process.
-
Prepare for the FOC date: Coordinate with your team so they know when the switchover will occur, especially if you’re porting multiple lines.
-
Test post-porting: Once the numbers are live with your new provider, test inbound and outbound calls to confirm everything’s functioning properly.
Taking these extra steps can help eliminate friction and ensure a smooth transition with zero downtime.

Frequently Asked Questions (FAQ)
