The Federal Bureau of Prisons Inmate Locator covers federal inmates and does not represent state or local jail custody. USA.gov provides a directory to state departments of corrections for state prison and prisoner information.
Choose the custody system. Separate federal, state, and local custody at the beginning of the lookup. A result from one correctional level should not be treated as universal custody coverage.
| Need | Official source | What it can establish |
|---|---|---|
| Federal custody. | Federal Bureau of Prisons - Inmate Locator. | Start with BOP when federal custody is plausible. Search by BOP register number if known (format #####-###), or by first and last name; middle name, age, race and sex can narrow namesakes. The locator covers federal inmates incarcerated from 1982 to the present, not all U.S. custody. |
| State prison | USAGov state corrections directory | Choose the relevant state department of corrections and its official locator or records contact. Use the agency-issued prisoner number if available, otherwise the person’s full name and any identifying filters offered. Keep the state and search date with the result; a BOP no-match does not search this separate system. |
| County/city jail or recent local booking | The jail operator or sheriff for the arrest/holding locality | Check the locality’s official inmate/booking-information page; use a booking number when available and compare names and dates. If there is no public locator or no reliable match, contact that jail’s records/inmate-information office. As a local example, Los Angeles County Sheriff provides inmate information online and through its inmate answering service, including booking, housing and release information. |
When the system is unknown, use the arrest locality, sentencing court or last known facility as the starting clue, then check the relevant federal, state and local branches above rather than assuming one nationwide search. A matching name alone is insufficient; confirm the source-issued register or booking number and other available identity details with the custodian.
In BOP, “Released” or “Not in BOP Custody” without a facility location means the person is no longer in BOP custody; another agency may still hold them, or they may be on parole or supervised release. Release dates may change during sentence recalculation. For pre-1982 federal records, use the National Archives route linked by USAGov. A no-match or old release entry is not proof of no custody anywhere; confirm the current holding agency before acting.
