Phone Number Porting: What Is It and How Does It Work?

Would you ever consider moving to a new country if it meant losing your passport and identity at the border for good? Of course not. So why treat your phone number any differently?

That fear of losing your digital identity is precisely what phone number porting solves. Let’s say John from Texas switched to a new phone from his old one. Phone number porting helps him keep the same old number he’s used for years.

In this blog, you will learn about phone number porting and how it works in detail. Let’s break down the details and key information you need to know.

What is Phone Number Porting?

Phone number porting is the process of shifting your present phone number from one phone service provider to another. It allows users to switch from one mobile network to another without changing their current number, using a modern business phone system.

It also enables users to move from a landline to a VoIP provider while keeping the same number. Think of phone number porting like filing a change of address for your mail. You’re not changing your name (your number); you’re simply telling the telecommunications system where to deliver your calls now.

Example of number porting: Imagine a local bakery, “The Sweet Spot,” has used the same landline number for 20 years. They want to upgrade to a modern VoIP business phone system from Dialaxy to access top features such as an auto-attendant and call recording. By porting their number, all their loyal customers can still call the number they know, but the calls will now be answered through Dialaxy’s flexible, cloud-based system.

The Step-by-Step Working Process of Phone Number Porting

While your new provider will handle the technical aspects, understanding the phone number porting process involves understanding what happens behind the scenes.

1. Initiate the Request: Choose your new provider and request to start the port by submitting an Authorization Letter. It is also known as a Letter of Authorization(LOA). This document lets your new provider act on your behalf.
2. Request Porting: During the sign-up process, inform your provider that you want to transfer your phone number.
3. Necessary information verification: After requesting porting, verifying the carrier checks, and reviewing all information on the Letter of Authorization (LOA), including name, address, and account number with the current phone company.
4. Approval and scheduling: Once verified, the port is approved for use. Both carriers agree on a Firm Order Commitment(FOC) Date. FOC date is the exact date and time the switch will occur.
5. Activation: After the FOC date, your new number is activated on the new network. Once the porting is completed, the old service is automatically disconnected.

Top 5 Reasons to Port Your Phone Number

1. Preserve Your Existing Phone Number: Your number is a part of your business or personal identity. Porting it will ensure that you do not lose valuable contacts or lose track of them.

2. No Loss of Service: Porting helps in an uninterrupted transition to another carrier without any disruption, so you’re never disconnected.

3. Enjoy Enhanced Features: Porting your number to an advanced provider typically unlocks features, such as voicemail-to-email, call forwarding, and mobile apps with unlimited calling plans and features.

4. Minimize Communication Costs: Porting your number while keeping it can minimize the cost of phone bills and business texts without the hassle of notifying everyone about a new number.

5. Enjoy Freedom of Provider Choice: Number portability gives you the flexibility to choose telecom services at will, without being bound to a particular provider.

What are the Benefits of Phone Number Porting?

While preserving constant and unbroken communication, porting a phone number offers convenience, flexibility, and control.

1. Preserve Brand Continuity

Even when you move to a new provider, you can preserve familiarity and professionalism by porting your number. No unanswered calls, no perplexed customers. Keep your number to maintain familiarity and professionalism so every incoming call is answered.

2. Unlock Modern Features

By porting your phone number, you can keep your current number while having access to modern features like wifi calling, voicemail-to-email integration, call routing, auto-attendants, and mobile app compatibility.

Pre-Porting Checklist: What to Know Before You Transfer Your Number?

Before you start the port, preparation goes a long way. Make sure you collect these key pieces of information to ensure you’re ready for a successful transfer.

1. Keep Your Number Active: Don’t cancel your current service yet. Keep your number active, and your new provider will handle the switch.
2. Check Your Account Info: Make sure your account name, address, number, and PIN (if any) are accurate. Wrong details can delay the transfer.
3. Have a Bill Ready: Some providers may ask for a recent phone bill, especially for business, landline, or toll-free numbers.
4. Clear Any Balances: Porting is often allowed with dues, but paying off bills or ending contracts can speed things up.
5. Confirm Number Eligibility: Not all numbers can be ported. Check if your virtual, toll-free, or Google Voice number qualifies.
6. Expect Minor Downtime: There may be brief service gaps during the switch, but most features resume quickly after porting.
7. Notify Your Team or Clients: Let others know when the port will happen to avoid missed calls or confusion, especially for businesses.

Types of Phone Numbers Eligible for Porting

Not all numbers are portable from one provider to another, but most typical numbers are. The following are the main categories:

1. Mobile Numbers

Most mobile phone numbers can be rapidly ported from one carrier to another, whether switching between major carriers or transitioning to a VoIP provider.

2. Landline Numbers

Traditional fixed-line phone numbers that have a physical location can, in most cases, be ported to a new service provider, such as when moving to VoIP systems.

3. Toll-Free Numbers

Toll-free numbers (those that start with 800, 888, or any other toll-free prefix) are portable, and companies can maintain their customer contact lines uninterrupted.

4. VoIP (Voice over Internet Protocol) Numbers

Numbers currently hosted on VoIP platforms are portable to other VoIP service providers or telecom operators. Numbers hosted on VoIP platforms, including many Google Voice numbers, are portable to other phone service providers.

5. Virtual Phone Numbers

These are virtual phone numbers that aren’t linked to a physical line but are used for forwarding or business purposes. Numerous virtual numbers can be ported, depending on the provider.

How Long Does Phone Number Porting Take?

How long it takes to port your number also depends on the type of number and providers, but here is an approximate idea:

Mobile-to-Mobile: It’s the fastest type of port. It takes around a few minutes to 24 hours. In many cases, it’s completed within a few hours.

Landline or VoIP to Mobile /VoIP: This process is complex and takes a longer time. The standard timeframe is 5 to 10 business days. It can sometimes take up to 4 weeks for very complex ports.

Toll-free phone number (e.g., 800, 888): These have their own specific process and typically take 7 to 10 business days to port.

Generally speaking, porting occurs within 1 to 3 business days; however, it may take longer if any issues arise.

Key Factors Affecting Porting Time

• Type of Number(Biggest Factor)
• Accuracy of Information
• Current Provider’s Response Time
• Country Regulations
• Outstanding Payment or Contracts
• Porting During Business Hours

Common Problems: Why Ports Get Rejected & How to Fix Them?

Let’s be honest: there’s nothing more annoying than getting an email that your number port has been delayed. Before you get discouraged, you should know that almost all porting problems come down to a few simple slip-ups. The great part is that once you know what to look for, you can avoid these issues entirely. Here’s a look at the usual suspects and how to fix them.

1. Wrong Account Information

Why does it happen?

Your name, address, account number, or PIN doesn’t match with your current provider’s record.

How to fix it:

Double-check your details before submitting the port request. You can also contact your new existing provider to confirm everything is accurate.

2. Inactive or Disconnected Number

Why does it happen?

When you try to port a number that has already been disconnected, or let’s say, already deactivated.

How to fix it:

Ensure your number is still active before initiating the port. If the number has been disconnected, contact your provider. Some carriers grant reactivation within a limited period.

3. Outstanding Balance or Contract

Why does it happen?

If you are still using the current provider’s services, or are still under contract, or have an outstanding payment plan.

How to fix it:

You must settle any unpaid bills and ensure you check your contract status. However, the porting is still allowed in this case in many places. Providers may delay the porting process until dues are cleared.

4. Number Not Eligible for Porting

Why does it happen?

Some of the numbers are not eligible for porting. Numbers such as toll-free numbers, temporary numbers, or numbers outside the region do not support cross-type porting.

How to fix it:

Always ask for validation from the provider. Confirm eligibility with your new provider before requesting the port.

5. Too Many Port Attempts

Why does it happen? 

Trying failed port attempts multiple times may cause a temporary hold or flag on the number.

How to fix it:

Always pause and review what went wrong before submitting again. Contact both providers to clarify and resolve the issue first.

The Post-Porting Checklist: What to Do After Your Number is Moved?

1. Test Your Number: Make a few test calls and send texts to confirm your number is working correctly on the new network.
2. Check All Features: Ensure top features like voicemail, call forwarding, caller ID, and other features are functioning as expected.
3. Update Your Contact Info: If you use your number on websites, business cards, ads, or social media, double-check that everything is up to date.
4. Inform Customers & Partners: Let your clients, vendors, and team know that your number is active and fully functional.
5. Review the Final Bill from the Old Provider: Check for early termination fees, outstanding charges, or refunds.
6. Remove Old Account Apps or Settings: Delete old provider systems and disconnect any unused devices or features.
7. Secure Your New Account: Set a strong password or PIN to protect your number and account from unauthorized access.
