The Office of the Comptroller of the Currency accepts and reviews charters of federal and national banks. Trust banks are also expected to follow the guidelines specified in the comptroller's handbook. Since most national banks are credit card banks, they fall under the control of the Office of the Comptroller of the Currency.
State-chartered banks, however, obtain their charters from the banking regulator of the respective state. They are insured by the Federal Deposit Insurance Corporation.
