  • SMS one-time codes also protect adding transfer recipients, unless you use a USB security key.
  • Zelle in Bank of America needs a U.S. mobile number added to your contact info.

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.
