Why the line type matters
Social networks often check whether a number is mobile, landline or VoIP before sending a code, and many turn VoIP numbers away. TwinNumber numbers are registered as mobile.

XQuestions
Will this number appear on my LinkedIn profile?
No, a number added for sign-in and security stays private; showing a phone on your profile is a separate Contact info field.
Why can I not remove my old number?
LinkedIn may block removing a number used for two-step verification, so turn two-step verification off first.
Do I need to live in the U.S.?
No. TwinNumber works from 150+ countries with just a browser and an internet connection.
Is TwinNumber affiliated with LinkedIn?
No. We test our numbers with popular services and publish the results. LinkedIn is a trademark of its owner.
What if a code doesn't arrive?
Request a new code, then check your inbox and notification settings. If it keeps failing, contact us and we'll look into it.
