How to Use the Federal Inmate Locator
The Federal Bureau of Prisons Inmate Locator helps the public find people who have been in federal Bureau of Prisons custody, generally from 1982 to the present. It can show a location, register number, age, race, sex, and projected or actual release information.
It is not a universal jail, prison, immigration, probation, or warrant search. A careful result begins with the correct identifier and ends with confirmation from the appropriate agency when the information matters.
Quick Answer
Open the official BOP Inmate Locator, search by the person’s BOP, FBI, DCDC, or INS number when available, or use full name plus age, race, and sex. Confirm the register number and facility. Read release dates as estimates where indicated. If no result appears, check spelling, historical coverage, state and county custody, immigration detention, military custody, and the sentencing court.
What the Locator Covers
The official tool at BOP Inmate Locator is designed for federal Bureau of Prisons records. The agency explains that the database generally covers federal inmates from 1982 to the present, although historical information and current status can require additional inquiry.
| Result or source | What it can tell you | What it cannot establish alone |
|---|---|---|
| BOP register number | Unique BOP identity | State or county custody |
| Current facility | Published BOP location | Exact housing unit or real-time movement |
| Projected release date | Current calculation estimate | Guaranteed release day |
| Released status | No longer in BOP custody as listed | Freedom from all other custody or supervision |
| Not found | No match under the search and coverage | No federal case, warrant, or older custody |
Choose the Best Search Method
Search by number
A BOP register number is the most precise option. The tool also accepts certain FBI, District of Columbia Department of Corrections, and immigration file numbers. Copy the identifier exactly from a court document, prior result, attorney communication, or official notice.
Search by name
Enter the first, middle, and last name as accurately as possible. Use age, race, and sex filters to narrow common names. Try former names, hyphenation differences, initials, and known aliases, but do not assume a partial match is the correct person.
- Compare full name and suffix.
- Check age against the date of birth.
- Match case geography and sentencing date.
- Record the register number for future searches.
- Confirm the result through the sentencing case when identity remains uncertain.
Interpret Facility Information
A displayed facility links to a BOP institution page with address, phone, visiting, mail, and other information. Transfers can occur for classification, treatment, court, security, or release preparation, and the public page may not reflect a movement immediately.
Do not send money, documents, or personal information based only on a message from someone claiming to be an inmate. Confirm the register number and use BOP’s official communication and deposit instructions.
Understand Release Dates
A projected release date can change because of sentence computation, jail credit, good-conduct time, court orders, earned-time credits, disciplinary action, detainers, or other legal developments. The locator’s date should be described as published or projected, not guaranteed.
A result such as “Released” or “Not in BOP custody” does not prove the person is not in a halfway house, home confinement, state custody, immigration custody, local custody, or federal supervised release. The exact wording and date matter.
What to Do When No Record Appears
- Check spelling, spacing, surname order, aliases, and age.
- Search by register number if one can be obtained.
- Confirm whether the case was federal rather than state or local.
- Check state corrections and county jail systems.
- Review the federal court docket for sentencing and custody clues.
- For pre-1982 records, follow BOP or National Archives guidance.
- For immigration detention, use the responsible immigration agency’s official locator or contact process.
A federal conviction can result in probation, time served, or another outcome without a current BOP record. Sealed proceedings and recent transfers can also limit what a public search reveals.
Contact the Facility or BOP
Use the phone number and mailing address listed on the official facility page. Staff may confirm limited custody or communication information but will not disclose protected medical, disciplinary, safety, or investigative details.
For sentence computation, release, or legal questions, the inmate, attorney, or authorized person may need to use institutional administrative processes or contact the sentencing court. A facility switchboard cannot provide legal advice.
Send Mail and Money Safely
Follow the institution’s exact format for the inmate name and register number. Read current restrictions on paper, photos, publications, packages, and legal mail. Mail can be rejected when the address is incomplete or contents violate policy.
Use only the official BOP deposit methods described on the BOP website. Scammers may impersonate inmates, relatives, lawyers, or officers and request urgent gift-card, app, or cryptocurrency payments.
Visiting and Communication
Finding a person does not automatically approve visitation. The inmate usually initiates an approved visitor process, and the institution sets schedules, identification rules, clothing rules, and security procedures. Confirm the visit before traveling because lockdowns and transfers can change access.
Telephone and electronic communication are controlled services and may be monitored under applicable rules. Do not use another person’s account or attempt to bypass approved channels.
Privacy and Responsible Use
Custody information can affect family safety, employment, housing, and reputation. Verify identity and procedural status before repeating it. The listed offense or sentence may not capture appeal, resentencing, or later relief.
Do not use locator data to threaten, harass, expose relatives, or arrange unauthorized contact. Victims who need notification should use the prosecutor, court, or official victim-notification system.
Writer’s Opinion
The register number transforms the locator from a broad name search into a reliable tracking key. Anyone who expects to check status more than once should save it along with the sentencing court and case number.
The locator is strong at answering a narrow question—whether and where a person appears in BOP custody. It is weak when asked to describe a complete criminal history, supervision status, or future release with certainty. Those questions require court and agency records.
Frequently Asked Questions
How far back does the BOP locator go?
It generally covers federal inmates from 1982 to the present; older records may require archival research.
Does it include state prisoners?
No. State departments of corrections and county jails maintain separate systems.
Why did the facility change?
Transfers can occur for many administrative, court, medical, security, or release reasons. Public information may be limited.
Is the release date final?
It can change. Treat a published future date as projected unless the agency states otherwise.
What does “not in BOP custody” mean?
It means the locator is not listing current BOP custody; another form of custody or supervision may still exist.
Can I search by date of birth?
The public name search uses age and other filters rather than always displaying a full date of birth.
Can I visit after finding the inmate?
No automatic right or approval follows from the search. Complete the institution’s visitor process first.
Is the inmate locator a warrant search?
No. It is a custody locator, not a nationwide warrant database.
Executive Summary
Use an official identification number whenever possible, verify name-search matches, and save the BOP register number and facility link. Interpret release information as the locator labels it.
Check courts or other custody systems when the tool does not answer the question. Use official mail, deposit, and visiting channels and protect everyone’s privacy.
