As part of the U.S. Department of the Treasury, the Bureau of Engraving and Printing (BEP) is responsible for the printing of all currency notes. The bureau prints billions of Federal Reserve Notes, or dollars, each year for delivery to the Federal Reserve System, which makes sure enough currency and coins are in circulation. The coins are produced at the Mint. The organization offers tours and exhibits, and researchers can use the Bureau's Historical Resource Center which includes two million objects related to the history of engraving and printing for the federal government. Paper money was not utilized until the start of the Civil War, so the Bureau of Engraving and Printing has its origins in legislation enacted to help fund the Union Army. In the first years of paper money, workers printed and trimmed currency notes by hand. Over time, the Bureau was also tasked with printing stamps. In 1877, the BEP became the sole producer of all United States currency. Today, the BEP no longer produces postage stamps and has an additional production facility in Fort Worth, Texas.
Along with printing currency, the Bureau of Engraving and Printing also advises federal agencies on matters of document security. Also, it processes claims for the redemption of currency that has been damaged. The bureau has ongoing research efforts to improve automated production of currency and deter counterfeiting in currency and other security documents.
