Any financial institution (credit union or a bank such as USAA Bank) can issue a cashier's check, but it is normally required that you have a bank. Two: I deposited a small cashier's check ($) into my USAA checking account. This is not my primary checking account, but I do have. If you don't have a bank account, it's probably worth opening one. You can also purchase a money order instead of a cashier's check if you have cash and no.
