Second phone number

A second phone number, on the phone you already own

2ndLine offers a secure business line or second phone number without the hassle of adding a second SIM card or carrying an extra phone. Choose a real number in the USA, Canada, UK, Europe or Australia, then call and text over Wi-Fi or mobile data in under a minute.

Why it works

What you get

  • A real phone number

    Dedicated digital numbers that call and text like a standard mobile line.

  • No second SIM

    No extra hardware or SIM card: it runs on your existing internet connection.

  • Keeps life separate

    Keep your 2ndLine number separate from your primary phone number.

  • Screened and recorded

    AI spam blocking, call screening, recording and voicemail transcripts.

What a second line is for

A second phone number is a separate line that lives in an app on your current phone. You choose the number, you decide who gets it, and you can keep it as long as you need it.

Most people use one to separate work from private life, to sell and buy without exposing a personal number, or to stay reachable on a local number abroad.

How it is different from a burner

A burner is disposable and basic. A 2nd Line number is a proper line: voicemail with transcripts, call recording, forwarding, picture messaging and multiple numbers on one phone.

Our reliable app guarantees you never miss a call or message, even when the app isn’t open. It’s as real as it gets!

Works on your phone and your computer

Take your business line everywhere with you, accessible on all your mobile devices.

With Web Messaging you can answer the same number from your browser, using the same account as the app.

Numbers where you need them

Real phone numbers in USA, Canada, Finland, Germany, Mexico, UK, Australia + many more in Europe & beyond.

Pick the country and area code that match your customers, or hold numbers in several markets at once.
