How to Use the Federal Inmate Locator
The Bureau of Prisons offers a free online tool called the Inmate Locator. It covers every federal inmate from 1982 to today. Users can search by first name, last name, registration number, age, or state of residence. The system shows current location, security level, housing unit, and projected release date. Because of the First Step Act, sentence reviews happen every three months. This means release dates might be outdated by up to 30 days. Always double-check close to the expected release. The locator updates daily but may lag behind real-time changes. It’s best for verifying custody status, not last-minute travel plans.
