Inmate Lookup offers a simple and free inmate search for individuals in every jail, prison, and detention center in the United States. You can conduct a free inmate search online using either the first or last name of an offender and the race, age, or gender of the individual. Alternatively, you can find an inmate if you have the Bureau of Prisons (BOP) Register Number, District of Columbia Department of Corrections (DCDC) Number, Federal Bureau of Investigation (FBI) Number or Immigration and Naturalization Service (INS) Number. Information (such as location/offenses/projected release date) can be found online, by e-mail, or by telephone by contacting the state department of corrections or Federal Bureau of Prisons managed by the Department of Justice or visiting Inmate Lookup.
