The Federal Deposit Insurance Corporation (FDIC) provides insurance that guarantees deposits for depositors of member banks up to $250,000 per depositor per bank. FDIC insurance covers all depositors: businesses, individuals, trusts, municipalities, for profits, non profits, all depositors.
Not all depositories offer FDIC insurance, however. Those that do will post a sign or plaque in the lobby stating that “deposits are backed by the full faith and credit of the United States Government”. Look for that sign or plaque. If you don’t see it, don’t assume it is an FDIC member bank. Ask one of the employees.
