The Bureau of Engraving and Printing (BEP) was founded on 26 August 1862. At first, employees signed, separated, and trimmed sheets of Demand Notes in the Treasury building. Later on, there was more and more work including engraving and printing. After few years, the Bureau was producing Fractional Currency, revenue stamps, government obligations, and other security documents for many federal agencies. In 1877, the BEP became the sole producer of all United States currency. Moreover, the addition of postage stamp production to its workload in 1894 established the BEP as the nation's security printer, responding to the needs of the U.S. Government in both times of peace and war.

Today, the Bureau of Engraving and Printing no longer produces government obligations or postage stamps, but it still holds the honor of being the largest producer of Government security documents with production facilities in Washington, DC, and in Fort Worth, Texas.
