A U.S. number your bank will accept. Wherever you live.
U.S. banks and fintech apps send sign-up codes, sign-in codes and fraud alerts to the phone number on file. TwinNumber gives you a real U.S. mobile number for them, and you use it from your browser.
Why banks are strict about phone numbers
Your phone number is part of how a bank confirms who you are: it receives the codes that approve sign-ins, new devices and payments. Many banks look up the line type and turn VoIP numbers away, and a foreign number isn't accepted for every kind of account. A TwinNumber is registered as mobile, so it goes through the same check as a number from a U.S. carrier.
Tips
- 01
Pick a number to keep
Banks treat a phone number change as a security event, which can mean extra checks or a delay on transfers. Put the number you plan to keep on the account from the start.
- 02
Turn on notifications first
Switch on browser notifications or email copies before you apply, so you see codes and fraud alerts while they're still valid.
- 03
Match your company paperwork
Use the same number on your bank application, your formation documents and your EIN paperwork, so the details line up when the bank reviews them.
Questions
Why did my bank reject my Google Voice number?
Google Voice numbers are VoIP lines, and many banks turn VoIP numbers away when they look up the line type. A TwinNumber is registered as mobile.
Can I receive fraud alerts and calls from my bank?
Yes. Texts arrive in your inbox in the browser, and you can answer calls there or forward them to your own phone.
Can I use one number for my business and personal accounts?
You can, but a separate number for each company keeps codes apart. One TwinNumber account can hold several numbers, each with its own inbox.
Does a U.S. number mean my account will be approved?
No. Each bank decides who can open an account based on its own requirements, such as your identity and company documents. A U.S. mobile number takes care of the phone part of the application.
