Find someone in federal custody

The BOP's free inmate locator covers people in its custody from 1982 to the present. Search by name, or by the 8-digit register number if you have it. Step by step: federal inmate search, with a page for every BOP prison.

People waiting for a federal trial are often held for the U.S. Marshals Service in a county jail or private facility, so they may appear in a county roster instead. Search by name at the top of this page.
