According to the Federal Reserve Board, there are twelve Federal Reserve Districts throughout the United States. These include New York, Boston, San Francisco, St. Louis, Dallas, Chicago, Richmond, Cleveland, Philadelphia, Minneapolis, Kansas City and Atlanta.
The largest Federal Reserve District is San Francisco, while the smallest is Philadelphia. In the 12th District, the Seattle Branch serves Alaska and the San Francisco Bank serves Hawaii. Similarly, the New York Bank serves Puerto Rico and the U.S. Virgin Islands. In addition, the Board of Governors meets near the border between the Richmond and Philadelphia Districts. All district boundaries were revised in February 1996 by the Board of Governors, explains the Federal Reserve Board.
