What Facebook Marketplace uses your number for
- Adding a mobile number to your account may ask for a confirmation code sent by text.
- Two-factor authentication can text a 6-digit code to a number on your account.
- Facebook recommends keeping an email on the account too, in case you lose access to your phone.

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.

Can I use an authenticator app instead of texts?
Yes. Facebook also supports a third-party authentication app or a security key. If you turn off your only mobile number without one of those, two-factor authentication turns off too.
Why didn't my Facebook confirmation code arrive?
Facebook's help says to make sure mobile texts are turned on for your account.
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 Facebook Marketplace?
No. We test our numbers with popular services and publish the results. Facebook Marketplace 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.
