Businesses everywhere embrace the benefits of implementing a digital small business phone system.
One advantage of modern communications solutions is utilising virtual phone numbers.
These numbers empower users to make and receive calls from any internet-connected device, allowing businesses to operate more efficiently and flexibly.
In this article, we take a look at what exactly is involved in getting a virtual phone number for your small business. You might be surprised at how simple it is!
What Is a Virtual Phone Number?
A virtual phone number works just like a regular phone number but it lives in the cloud, so it isn’t tied to a landline.
These numbers are configured so that users can make and receive calls on any internet-connected device, including through a softphone on a laptop, a mobile app, or with a VoIP phone.
When you sign up for a VoIP small business phone system, you will be able to assign and manage virtual phone numbers for your team from the system dashboard. Typically, it takes just a few minutes to set up.
There are plenty of benefits of having a virtual phone number, including:
- Cost savings on long-distance calls
- Enabling you to establish a local business presence and expand your business globally
- Flexibility to handle calls from anywhere in the world
- Access to advanced calling features such as call recording and voicemail to email
How To Get a Virtual Phone Number in 5 Steps
Getting a virtual phone number is easy and can be done in just five easy steps: choosing your VoIP provider, picking your virtual phone number type, choosing a new number or port, setting up call handling and finally, downloading the app.
Step 1: Choose a Cloud Telephony (VoIP) Provider
Compare providers on price, call quality, UK coverage, support and the features you actually need. Check for contract lengths and exit fees before you commit.
Step 2: Pick Your Number Type
Decide whether you need a geographic number (e.g. 020 for London), a non-geographic 03 number, or a freephone number. Each one affects how customers perceive your business.
Step 3: Choose a New Number or Port Your Existing One
You can take a brand-new number or transfer the number you already use, so customers never notice a change. Porting usually takes a few days, so start before you need it.
Step 4: Set up Your Call Handling
Add your business hours, greeting, call divert, voicemail-to-email and call flows so calls reach the right person or device.
Step 5: Download the App and Make a Test Call
Install the mobile or desktop app, then call your new number from another phone to check audio quality and routing.
Types of Virtual Phone Numbers
There are a range of different virtual phone numbers and all with a specific use, from a landline-style number to a local number to give your business a larger presence:
Geographic (landline-style) Numbers
These show a local area code (e.g. 0161 Manchester, 0121 Birmingham). They build local trust and suit businesses serving a specific area.
Non-geographic 03 Numbers
These are UK-wide and cost the same as calling a geographic number. They suit businesses that want a national presence without a local identity.
Freephone (0800/0808) numbers
Callers pay nothing. They suit sales lines and customer service, but the business pays the inbound call costs.
Mobile-style (07) numbers
These suit sole traders who want a separate business line on their own phone.

Typical cost breakdown
