About SecondLine
We're on a mission to give everyone control over their phone identity — without compromise.
SecondLine started in 2024 with a simple idea: your phone number shouldn't be tied to your SIM card, your carrier, or your personal life. We believed people deserved a number they could turn on for work, turn off for the weekend, or hand out without worry. Today, hundreds of thousands of people use SecondLine to keep their personal number private, run their business, and stay connected across borders.
Our mission
Phone numbers have quietly become one of the most personal pieces of identity we own. They unlock our bank accounts, our social media, our medical records — and yet most of us hand them out dozens of times a year to strangers, websites, and businesses we'll never hear from again. We're building the tools to fix that: private, flexible, affordable phone numbers for every part of life.
