Where are US dollar bills made?

Answer 1

All US paper money is made by the Bureau of Engraving and Printing at facilities in Washington and Fort Worth. Bills printed in Fort Worth have a tiny "FW" to the left of one of the plate numbers in a corner of the bill's front, e.g. FWC2

Regardless of popular myth, the Mint only makes coins and has nothing to do with printing paper money. The Mint and the BEP are completely separate parts of the Treasury Department.
