As the world moves away from regular phone lines, many businesses are wisely switching to digital phone systems, most often Voice over Internet Protocol (VoIP). These systems have more features, can grow with your business, and are cheaper, making them better for a modern workplace. But what happens to the phone number for your current business? The good news is that you don’t have to give it up.
What Does It Mean to Port a Number?
Number porting is the process of moving your phone number from one service provider to another. For example, you could move your number from a traditional landline carrier to a VoIP provider. The goal is to move your business number to a digital system without changing the number itself. This lets you:
- Stay in touch with clients
- You can save time and money by not having to update your websites, signs, and business cards.
- Keep your communication tools up to date while still being familiar with them.
Why Migrate to a Digital Line?
Before we get into the how, let’s take a quick look at why a lot of businesses are making the switch:
- VoIP calls usually cost less than regular phone calls, especially for long-distance or international calls
- Scalability: You can easily add or remove users without changing the hardware
- More advanced features include auto-attendants, call forwarding, voicemail-to-email, mobile apps, and more
- Flexibility: Employees can make and receive calls from anywhere they have an internet connection
- Future-proofing: As landlines are phased out (like the UK’s PSTN switch-off by 2025), digital lines will become the norm
What If You Need Multiple Numbers or Locations?
No problem. Most digital phone systems are made to be flexible. You can port multiple numbers at once, set up virtual numbers for different departments or regions, and send calls to the right devices or places in a smart way. This flexibility is especially useful for businesses that are growing, teams that work from home, and companies that are going global.
Step-by-Step Guide to Migrating Your Number
Although the process may seem extremely complex, there are steps you can follow to ensure the process goes smoothly.
Choose a Reliable Digital Phone Provider
Do some research and choose a VoIP provider that meets the needs of your business. Think about:
- Plans and costs every month
- Features that are available, such as mobile apps, CRM integration, and call recording
- Help for customers
- Reviews from users and promises of uptime
Check Number Porting Availability
After you pick a provider, make sure that your current business number can be ported. Most providers will let you check by entering your number on their website. Ensure your current phone number is working while you do this. You can’t port a number that has already been disconnected.
Gather Your Information
To move your number, you need to know a few things:
- The name of your current provider
- The phone number(s) for your business
- The account number that goes with it
- A recent bill for a phone call or a record of customer service
- The name and service address of the account holder
Accuracy is very important. If the information from your old provider and your new provider doesn’t match, the port may be delayed.
Submit a Letter of Authorisation
Your new provider will ask you to sign a letter giving them permission. This letter lets them act on your behalf and ask your current provider to move your number. Some providers let you do this online, while others may need a PDF that you sign.
Wait for the Porting Process to Complete
The porting process starts after you send in the LOA and other documents. Depending on the kind of number, how quickly your current carrier responds, the number of lines that are being moved, and when your number goes live on the new system (you’ll usually get a porting date), this could take a few days to a couple of weeks. During this time, everything stays the same. You can keep using your old system until the switch is complete.
Tips for a Smooth Transition
Don’t Cancel Your Old Service Prematurely
Don’t cancel your current phone service until your number has been successfully ported. You could lose the number for good if you disconnect it too soon.
Plan for Downtime (Just in Case)
Most of the time, ports work fine, but there can be short delays on the day of the switch. Tell your team and make sure you have a backup plan for communication if you need it.
Test Your New System
Once the number is live, make sure everything is working right by testing both incoming and outgoing calls, including voicemail, call routing, extensions, and more.
Train Your Team
Give your staff a quick rundown of what the new system can do. Most VoIP platforms are easy to use, but a little training can help people get used to them.
Upgrade Without Losing What Matters
One of the easiest ways to modernise your communications without losing your brand identity is to move your business number to a digital line. The process is easy with the right provider and some planning, and the benefits are well worth it.
Digital phone systems are made for the future of business. They have clearer calls, smarter features, and lower prices. And the best part? Your customers won’t even notice the change, except that you might never miss a call again.
