EARLY ACCESSTwinNumber is launching soon. Reserve your spot for a U.S. mobile number.

Use TwinNumber with Lili.

Opening a Lili business account for your U.S. company? Lili's standard application asks for a U.S. mobile number, not a VoIP one, while non-U.S. citizens can give a U.S. or international number. Use a real U.S. mobile number for the application and the verification codes that follow.

What Lili uses your number for

  • The standard Business Checking application asks for a U.S. mobile number with a major carrier.
  • Your number on file receives verification codes and security alerts.
  • Signing in from a new device or location, including from abroad, can ask for extra verification.

Why the line type matters

Banks 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.

Questions

Can I use a VoIP number on Lili?

No. Lili asks for a U.S. mobile phone number with a major carrier and says no VoIP numbers. TwinNumber numbers are registered as mobile.

Can I open a Lili account without an SSN?

Only as a non-U.S. resident: Lili lets non-residents who are citizens of a supported country apply for a U.S.-registered business with a passport number instead of an SSN. Everyone else needs the owner's SSN, since Lili has to verify you as a person; a phone number never replaces that.

Why didn't my Lili code arrive?

Check that the number on your profile is right, wait a couple of minutes before asking again and use the most recent code, since each new one may cancel the last. Your carrier may also be blocking short codes.

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 Lili?

No. We test our numbers with popular services and publish the results. Lili 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.
