The Role of US Phone Numbers in Wise Business Accounts
Wise Business enables global companies to hold balances in over 50 currencies, convert funds at mid-market exchange rates, and obtain local US routing and account numbers. When establishing a US business profile on Wise, you must link a valid US phone number.
Wise relies on this phone number for 3D Secure (3DS) online card purchasing authentication, account recovery, and device pairing for team members.
