Every organization needs a secure, reliable business phone system to communicate with customers, employees, prospects and vendors. But for small businesses, fully featured types of business phone systems can be expensive and challenging to install and run. 

A virtual phone number is a cost-effective and feature-rich solution that will expand your business’s communication capabilities. If you’ve ever used FaceTime or called a corporate contact center for product support, the chances are that you were connected through a virtual phone number. 

Below, we explain what a virtual number is, set out eight of its main benefits and show you how you can obtain one for your business.

What is a virtual phone number?

A virtual phone number is a telephone number that isn’t tied to a specific device or location. Using voice-over-internet-protocol (VoIP) technology, virtual phone numbers let people make secure phone calls from anywhere with a solid internet connection.

Virtual numbers offer businesses a remarkable level of flexibility. Administrators can assign a virtual phone number to almost any area code, a process called direct inward dialing. Administrators can even assign toll-free numbers, which means customers aren’t charged when calling you.


You can choose a virtual local number to help you build trust since you’ll appear to be part of the community. Meanwhile, virtual toll-free numbers are ideal for companies that want to project a national presence. Not charging customers to call you also helps you present your business as a client-centered company.

Many virtual numbers offer free or reduced-cost long-distance calling that can substantially reduce your telephone costs. You and your customers will also benefit from the clean, clear audio virtual phone connections offer.

Unlike traditional phones, you don’t need a copper wire connection to the local exchange or a separate handset. This leads to significant cost-saving opportunities with VoIP-based virtual phone numbers. Each virtual line you connect doesn’t need physical hardware either, a significant cost saver over how telephone companies previously allocated and charged for lines. 

How do virtual phone numbers work?

Anyone with a desktop computer, laptop or mobile device can use a virtual phone number. A virtual line sends a call to another device over a fixed or mobile broadband internet connection by converting the audio from a phone line into a digital signal. These virtual lines are created and used in the cloud, rerouting calls to existing lines or team members’ devices.

You can bundle multiple virtual lines together to form a virtual switchboard. You only need one broadband connection for multiple lines, eliminating the need for separate physical lines that a traditional phone system requires. You don’t need a complex and expensive local private branch exchange (PBX) either.

Instead, you control your group of virtual phone numbers and how they interact with each other via an intuitive cloud PBX that’s easy to operate. From a desktop or mobile app, you can route calls, switch on call forwarding, activate voicemail, set up auto-attendants and more.

For example, an administrator in your company could log onto the cloud PBX and create a new virtual toll-free number (or an international toll-free service number for a global presence) that forward calls to individual team members’ devices in a contact center. For added flexibility, the representatives receiving the calls can choose the equipment they want to use, whether it’s a VoIP handset or an application like Zoom or RingCentral on their cellphone, tablet, desktop or laptop.

Virtual phone systems rarely become overwhelmed because virtual phone numbers use the cloud, not your local computers or devices. Since virtual phone calls don’t drain too much data, bandwidth concerns aren’t an issue.

Think of a virtual phone number as an intermediary for voice communication between two devices.

8 benefits of virtual phone numbers

Virtual phone numbers offer eight primary benefits that might appeal to your business. We’ll take an in-depth look at each. 

1. Virtual phone numbers incur lower costs.

One of the most significant benefits of virtual phone numbers is that they offer a much lower total cost of ownership than traditional landlines. When choosing a business phone system, you’ll find that traditional system costs add up quickly and become prohibitive, especially if your business is growing.

Because a virtual line doesn’t require specialized or dedicated devices, your hardware costs are virtually nothing. When you’re moving a business into new communities or regions, you can create a local number to avoid the added costs of long-distance calls. It’s essential to keep operating expenses as low as possible when opening your business to new opportunities and clients. Virtual phone numbers can help you do this.

Did You Know?Did you know

Another helpful virtual small business tool is a virtual answering service, which provides an automated response or directs calls to a third party that can forward calls and take messages.

2. Virtual phone numbers serve multiple markets.

Because anyone can get a virtual number for any location, you can create local numbers to serve any region. This decreases costs because you’ll avoid premium charges from long-distance calls as you find new neighborhoods and clients to serve. 

3. Virtual phone numbers are easy to scale.

Without the need for dedicated hardware and with no line limitations, creating more virtual phone numbers to scale with your business is easy. When you’re building a sales team and hiring more employees, you can call your administrator and add all the virtual phone lines you need.

4. Virtual phone lines allow for custom numbers.

When you have a memorable or toll-free customer support phone number, your customers gain a sense of security and recognition. Virtual phone numbers make it easy to create specific numbers to help your business look more professional. 

Whether it’s a toll-free number or a vanity number like 1-800-CONTACTS or 916-CALL-TUR, a virtual number can help create a brand identity. 

5. Virtual phone numbers allow for optimized call data and tracking.

It’s not easy to record, digitize and analyze a traditional call. But because a virtual call is already digital, it’s easy to record with the push of a button. You can seamlessly transcribe a virtual call, appraise it for relevant content and archive it.

With all the information a virtual number provides, a business can track key internal performance indicators, such as average call length and customer satisfaction, to improve its services.

Bottom LineBottom line

Within many customer relationship management (CRM) and virtual phone systems are data analytics tools. You can check how well individual teams and staff members are performing to their key performance indicators to find areas of improvement in your business.

6. Virtual phone numbers enrich your customer information knowledge. 

With an easy way to archive phone calls, a business that uses virtual phone services can quickly compile critical know-your-customer information, such as customer preferences and overall business trends. This kind of data helps an organization prevent fraud and comply with multiple government rules and regulations. 

Compliance is a particularly important factor for businesses in the banking, healthcare, financial services and insurance industries that rely on verifying a customer’s identity. [Related article: How  Health Insurance Portability and Accountability Act (HIPAA) Laws Impact Employers]

7. Virtual phone numbers improve security.

Creating a safe, secure phone line to conduct business is easier than ever with a virtual phone number. Because it uses VoIP, a virtual number can be encrypted and protected behind layers of firewalls and other security methods. These protections keep out prying ears, so you can keep your business running smoothly without interference. To ensure security, reach out to your internet service provider to ensure your virtual number is encrypted.

8. Virtual phone numbers improve flexibility. 

Because you can tie a virtual number to any PC or mobile device, you can receive calls from anywhere in the world. This allows your workforce to redirect calls to their preferred device. When traveling or working remotely, any employee can still answer a support call or call back sales prospects. [Related article: Creating a Remote Help Desk for Your Business]

Virtual phone number FAQs

Here are some of the most common questions on virtual phone numbers and how they work.

Absolutely. A virtual phone number works perfectly with regular phone lines. The only difference is how those calls are transferred. A virtual phone line is digital, while traditional phone numbers use a private branch exchange architecture with limited functionality.

>> Learn More: What’s an Interactive Voice Response?

Yes. You can assign multiple virtual phone numbers to an individual user or assign multiple users to a single virtual phone number. This allows additional flexibility for a company to automatically reroute numbers, which comes in handy when multiple simultaneous calls overwhelm a contact center.

Many service providers offer free virtual phone numbers. For paid services, costs range from $19.99 to $59.99 per month, depending on how many phone lines you need.

To create a virtual phone number for your business, you first need to sign up with a VoIP provider. During the registration process, they will offer you a choice of virtual phone numbers. Some also offer local and toll-free numbers, although this may be for an additional charge.

Most VoIP providers will allow you to create virtual landline numbers with an area code of your choice. The benefit of doing this is that it will make your business seem more local to your target audience if you’re launching or doing business in a particular geographical area.
