Where is paper money made?

BEP golden seal
The Bureau of Engraving and Printing (BEP), established in 1862, designs and prints all U.S. paper money. This agency, which is also part of The Treasury Deparment, also prints postage stamps and other official certificates.

The BEP's production facilities in Washington, D.C., and Ft. Worth, Texas, made almost 9 billions bills in one year. About 95% of them are used to replace worn out money. Even though bills are made of a special paper that is 75% cotton an 25% linen, they wear out pretty fast if they used a lot. The $1 bill only lasts an average of 22 months, while the $50 bill lasts 5 years and $100 bill lasts 8.5 years.
