The Federal Correctional Complex at Florence operates under dedicated ZIP code 81290 in Fremont County, Colorado. This Bureau of Prisons facility consists of four separate institutions: Federal Prison Camp Florence (minimum security), Federal Correctional Institution Florence (medium security), United States Penitentiary Florence High (high security), and the infamous ADX Florence. The ADX, constructed in 1994 and opened in 1995, is America's only federal supermax prison and holds the most dangerous inmates in the federal system.
Located approximately 100 miles south of Denver in the high plains of Fremont County, the complex spans 49 acres. This unique postal designation has served the complex for over two decades. Two delivery codes route mail to the facility. All inmate funds must be sent through a central processing center in Des Moines, Iowa, not directly to Florence. Florence is the valid mailing city for inmate correspondence, though all incoming mail undergoes security screening.
