The Federal Reserve Banks and Currency

Did you know that Federal Reserve Banks place the currency you use to make purchases into circulation? Each bill has a number and a letter that denote the Federal Reserve Bank that accounts for that particular bill. For example, a bill with the number 8 will have the letter H (the eighth letter in the alphabet), which means it appears on the balance sheet of the Federal Reserve Bank of St. Louis.

For the recently redesigned $5, $10, $20, $50, and $100 bills, the letter and number that identify the Federal Reserve Bank are beneath the left serial number on the face of the bill.
