Federal Prison Security Levels

The BOP operates institutions at different security levels and also uses detention, medical, transfer, complex, and reentry facilities. Security designations are based on the inmate’s needs and the institution’s controls; the official BOP facility page shows the current mission.

How to use the official locator

1. Open the official BOP Inmate Locator.
2. Choose Find By Name or Find By Number.
3. Enter only fields you know accurately.
4. Confirm the Register Number, age, status, and location.
5. Check state or county custody if the federal result is missing.

Minimum security

Federal prison camps generally have limited or no perimeter fencing and emphasize work and program assignments. Placement is determined by BOP classification, not by a public request.

Low and medium security

Low-security FCIs generally use double-fenced perimeters and dormitory or cubicle housing. Medium-security institutions generally have strengthened perimeters, more cell-type housing, and greater internal controls.

High and administrative security

High-security institutions are often called USPs and use highly secured perimeters and close movement controls. Administrative facilities have specialized missions such as detention, medical care, transfer, or treatment.

Complexes and current missions

A Federal Correctional Complex can contain institutions with different missions and security levels. Always open the current BOP facility page because names, security levels, and missions can change.

Information to prepare before searching

Have the person’s complete legal name, likely age or date of birth, and any document that shows a federal identifier. Do not guess demographic fields when the official form makes them optional. A wrong filter can remove the correct result, while a precise Register Number or correctly labeled agency number can reduce same-name matches.

How to confirm the correct federal record

Compare more than the displayed name. Review the BOP Register Number, age, status, facility, and projected release information together. If the facility is shown, open the current BOP facility page for contact and visitation details. A same-name result, an old screenshot, or a third-party profile is not enough to establish current federal custody.

When another custody search is more appropriate

The BOP locator does not replace state Department of Corrections or county jail systems. A person may be awaiting federal placement in a local facility, held by another federal agency, serving a state sentence, or recently transferred. Use the current housing agency first when reliable information identifies it, then search BOP after federal designation or transfer. Save the official identifier and recheck the current source instead of relying on an old screenshot.

Federal search limitations

• The online locator starts with records from 1982.
• A federal case does not guarantee current placement at a BOP facility.
• Projected release dates can change.
• A person no longer in BOP custody can remain under another agency or supervision.
