Online Telephone Number

Small businesses that lack a professional phone contact often struggle with customer trust and missed opportunities. An online telephone number provides a quick, affordable way to appear credible and reachable to customers anywhere.

This article explains what an online telephone number is, its benefits, and how to get one for your business.

What is an Online Telephone Number?

An online telephone number (also called a virtual number or virtual landline) is a phone number not tied to a physical phone line or SIM card. Learn more about what a virtual number is and how it works. It operates over the internet using Voice over IP (VoIP) technology. You make and receive calls through an app or software on any device with internet access. You can even choose a number from any area code or country without being there in person. To callers, it works just like any other phone number—they won’t even realize it’s internet-based.

Benefits of an Online Telephone Number

Using an online telephone number offers several advantages for entrepreneurs and small businesses. It helps you solve common communication problems and present a more professional image. Here are some key benefits:

  • Local presence and trust
    An online number lets you pick a phone number with a local area code where your customers live. People are more likely to trust and buy from a business that shows a local contact number.
  • Professional image
    Using a dedicated business number (instead of your personal phone) makes your venture appear more established. You can even set up a greeting or IVR menu on the number. That way, even a one-person business sounds more professional.
  • Privacy and work-life balance
    An online telephone number allows you to keep your personal number private. Give out the virtual number for business calls and switch it off after hours. This approach maintains clear boundaries between your work and personal life.
  • Cost savings and flexibility
    Online numbers are often much cheaper than a traditional phone line. There’s no need to buy extra SIM cards or hardware. You can take calls anywhere via the internet, which is great for remote work or travel. Many services offer pay-as-you-go or low monthly plans. For example, Sonetel provides phone numbers from just $1.79 per month.

How to Get an Online Telephone Number

Getting an online telephone number is straightforward and only takes a few minutes. You don’t need any special equipment or technical skills. Follow these basic steps to set up your virtual number:

  1. Choose a provider
    Research a reputable online phone number service that covers the regions you need. Consider pricing, available features, and whether they offer numbers in your target country.
  2. Sign up for an account
    Create an account with the provider. This usually involves providing an email and payment method. Some services may require ID verification, especially for certain countries.
  3. Pick a number
    Select a local or toll-free number from the provider’s dashboard. You can search by country, city, or area code to find a number that suits your business.
  4. Configure call routing
    Decide how you want to handle incoming calls. You might forward calls to your mobile phone or answer via the provider’s app or web interface. Set up voicemail greetings or business hours if needed.
  5. Start using your new number
    Once everything is set, test the number by making a call. Then add this number to your website, social media, and business materials so customers can reach you.
