As the primary publisher of government securities, the Bureau of Engraving and Printing produces Federal Reserve notes, U.S. postal stamps, identification cards and other security documents. More than 9 billion Federal Reserve notes are printed each year at the BEP facilities in Washington, D.C. and Fort Worth, Texas. The agency also conducts research to develop counterfeit deterrent technologies for all the documents it produces. The BEP posts information about the new currency in circulation. The BEP also redeems mutilated currency, bills that have been partially destroyed.
