Banks are financial institutions that take deposits and make loans. In the United States, banks can be chartered at the state or federal level, depending on size and operating scope. Community banks typically serve a small geographic area and are chartered at the state level. Regional banks are larger and often operate across more than one state. National banks are the largest segment in the country.
