The FSIN is the federal authority for the detention of suspected and convicted persons, the security and maintenance of prisons in Russia, the transport of prisoners, and rehabilitation programs. As of 2019, it operates 954 prisons and pre-trial detention facilities housing adult and juvenile offenders of various security levels, with the majority of penal facilities being corrective labor colonies. Its head office is located at Zhitnaya Street 14 in Yakimanka District, Central Administrative Okrug, Moscow. The FSIN was established in 2004 as a new federal correctional service agency for the Ministry of Justice to replace the Soviet-era Main Administration for the Execution of Punishments (Главное управление исполнения наказаний, GUIN), formerly of the Ministry of Internal Affairs, and received its current name in 2006. It claims succession from the Main Prisons Directorate of the Russian Empire founded in 1879, and directly succeeds the correctional services of the Ministry of Internal Affairs of the Soviet Union including the Gulag agency. Arkadiy Gostev has been director since 2021.
