What Is an Online Phone Number?

Online telephone numbers are telephone numbers that aren’t attached to a landline or a specific device. These web numbers can be used to make and receive calls on any device with a Wi-Fi connection because the numbers themselves aren’t connected to any specific SIM card or device, meaning any number operates as a phone number online.

Whether you need to establish a business number or shield your personal life, getting a second phone number through VoIP will give you both. You will be able to use multiple numbers on a single cell phone, letting you make and receive calls and texts on both numbers anywhere you go, as long as you have a stable Wi-Fi connection, all the while you keep your personal mobile phone number out of the public eye.

How Do Online Numbers Work?

Voice over IP is the driving technological force behind online numbers. In virtual telephony the number and phone features are not connected to a physical phone or equipment, but exist in online software.

This means you can get a number online from any area code in the U.S., without having to physically be there, as well as a toll-free one if you want a national presence. These numbers act as a second phone number, and do not replace your current one.

You won’t need to go through a traditional telecom provider or wire up your office with hardware if you opt to try an online phone service. You can make and receive calls and text on any device you want nearly everywhere you go, making the tech essential not only for companies looking to leave outdated solutions behind, but for people who travel for work or are constantly on-the-go.

If you have a VoIP phone service, customers won’t notice any difference when they call a number online versus a standard phone number. Virtual numbers work exactly the same as normal numbers linked to physical wires like landline numbers or sim cards, no one will know if your number is virtual telephony or not.

What’s the Difference Between Online Numbers and Traditional Numbers?

Online Numbers Traditional Numbers
Require a stable internet connection Attached to one device
Come with feature sets Tied to the country/geographical location
Can be used in any location Requires physical hardware
