An inmate's release date can be determined either online through a state or federal corrections website or by contacting the specific correctional institution where the inmate is housed. In order to obtain the release information, it is necessary to have the inmate's name and date of birth.
The Federal Bureau of Prisons offers an online inmate locator, providing the current location of the inmate, as well as his release date. The FBOP locator can search for inmates by the BOP register number or by name. To narrow the results, users can also search for inmates by race, age and sex.
The Florida Department of Corrections, as of 2015, has a similar Inmate Population Search function on its website. Users can search for inmates using the usual criteria, such as name, race and age, but the search results can be further filtered by criminal history, county of commitment and current housed location. The release date for the offender will appear in the search results. The Florida Department of Corrections site allows for a search including all criteria.
The Michigan Department of Corrections has a similar system for looking up inmates, which also discloses the inmate’s release date. The Michigan system is called OTIS, Offender Tracking Information System.
