Virtual Phone Numbers: 8 Things to Know Before You Get One

A virtual phone number can keep your personal number private, give your business a professional line or put a local number in another city in your pocket. It's quick to set up, but it isn't identical to the number your mobile carrier gave you.

Here are nine things worth knowing before you get one, so you know exactly what it does well and where your regular number still matters.

1. It's a real phone number A virtual number isn't a fake or a forwarding trick. It's a real phone number that people can call, save and call back. With the Second Number app, you can also send and receive texts from it. To everyone else, it looks like any other number.

2. You choose where it's from With a regular carrier, you usually get whatever number is assigned. With a virtual number, you choose. In the Second Number app, you pick a country and then choose your number. On Second Number for Teams, admins search for business numbers by area code, so a team can have a local number in each city it serves.

3. You don't need a second phone or SIM card Your virtual number lives inside an app on the phone you already have, or in a browser tab on your computer. There's no SIM card or eSIM to install and no second carrier plan. Your personal number keeps working exactly as before.

4. It runs over the internet Calls on a virtual number travel over Wi-Fi or mobile data. That's what makes it so flexible, since it works anywhere you're online. It also means call quality depends on your connection. A steady signal gives clear calls, and a weak one can cause choppy audio, so it's worth having a backup plan for places with poor coverage.

5. Keep your regular number for emergencies This is the most important point on the list. Second Number for Teams doesn't support emergency calls. Whatever second number you use, your regular mobile phone or a landline should always be your way to reach emergency services.

What about non-emergency calls?

Many situations feel urgent without being emergencies: a noise complaint, a minor fender-bender with no injuries, or reporting a theft after the fact. For these, you need the phone number for non-emergency police and city services. In many US cities, that's 311, a three-digit code the FCC set aside in 1997 for non-emergency police and other government services.

Not every city uses 311, though, and not every phone or calling app can connect to short codes like it. Look up your local police department's full ten-digit non-emergency number on its website and save it in your contacts, so it's ready when you need it.

6. Some services won't accept it for verification Many apps and websites will happily send a verification code to a virtual number. Some banks and services won't, because they only accept numbers from mobile carriers. If a code never arrives, use your regular number for that service. Keep your most important accounts, like banking and your main email, on your long-term personal number anyway.

7. For business calling, reputation matters If your team makes a lot of outbound calls, carriers watch how each number behaves. Lots of short or unanswered calls can get a number labeled "Spam Likely". Registering your business numbers with the Free Caller Registry, spreading calls across your team's numbers and calling people who expect to hear from you all help keep your numbers trusted.

8. Your personal number stays private It's one of the main reasons people get a virtual number. Share your second number on listings, sign-up forms, dating apps and with new clients, and your personal number stays with the people you choose. On Second Number for Teams, agents can only call out from business numbers your organization owns, so customers never see anyone's personal number.

How to get started For yourself: download Second Number from the App Store or Google Play, pick a country and choose your number. There's no account to create, and you get unlimited calling and texting from your new line. For your team: create a free account at 2ndnumber.co and have your organization verified. Then add credit, search numbers by area code and assign each one to the right person.
