As of 2015, you can find inmates in federal prisons through the Inmate Locator page on the website for the Federal Bureau of Prisons. This database of federal prisoners contains information for inmates incarcerated from 1982 forward.
Find a federal inmate with the Federal Bureau of Prisons website by searching his Bureau of Prisons register number. Other search options include entering a District of Columbia Department of Corrections number, an FBI number or an Immigration and Naturalization Service number. The database can also be searched by an inmate's first and last name. Visitors to the website who search by name can narrow results by entering additional identifying features, including race, age and sex.
Information returned following a search for an inmate in a federal facility includes register number, sex, age and race. It also contains a release date for the prisoner, which may have already passed or be in the future. The name of the facility in which the prisoner is or was incarcerated is also listed, along with his current status within the system.
The Federal Bureau of Prisons database contains records for federal prisoners that were sentenced for crimes, prisoners held prior to trial, prisoners held as material witnesses and prisoners held on civil contempt charges. The database also contains data on inmates convicted of felonies in the District of Columbia as these prisoners are housed in federal facilities.
