Federal Inmate Locator, Booking Status, Prison Location and Release Help
A federal arrest does not always lead directly to a federal prison. The person may first be held by the U.S. Marshals Service in a county jail, regional detention center, private contract facility or Bureau of Prisons detention center while the criminal case is pending.
This guide explains the complete search path: how to use a BOP register number, what “In Transit” or “Not in BOP Custody” means, how to locate a pretrial detainee, how to check the federal case, and what to do next for visits, mail, money, calls, transfers, release dates, medical concerns and older records.

Which federal inmate search should you use?
Use the Bureau of Prisons Inmate Locator. Search by register number whenever possible.
Check the BOP locator, then the federal court case and the U.S. Marshals district connected with the prosecution.
Prepare a National Archives request because many older federal records are not available in the online locator.

How to understand a federal inmate locator result
| Result field | What it means | What to do next |
|---|---|---|
| Name | The name associated with the federal inmate record. | Compare the register number and physical identifiers before assuming it is the correct person. |
| Register number | The primary BOP identifier displayed for the person. | Save it for mail, deposits, facility questions and future searches. |
| Age | Current age calculated from the recorded date of birth. | Remember that this may be the person’s present age even when the listed release occurred years ago. |
| Release date in the future | A projected date based on current BOP sentence calculations. | Treat it as subject to recalculation, court action, credits and administrative updates. |
| Release date in the past | The person was released from BOP custody on the displayed date when no current facility appears. | Check whether the person remains on supervised release or entered another jurisdiction’s custody. |
| Unknown release date | The confinement term is not determined, which can occur in pretrial, civil-commitment or unsentenced situations. | Use the federal court docket and contact the relevant facility or U.S. Marshals district. |
| Facility name | The current publicly displayed BOP institution. | Open the institution page for mailing address, phone, visiting rules and local instructions. |
| Regional Office | The BOP says this can indicate a person serving a concurrent state sentence in a state prison. | The state correctional system may provide the usable physical location. |
| CCM | Community Corrections Management supervises contract community placement; the person is not necessarily housed at the CCM office. | Do not mail or visit the CCM office without confirmed placement instructions. |
| In Transit | The person has moved from a BOP facility and the destination is not publicly displayed. | Pause visits, packages and facility mail until a destination appears. |
| Released | The person is no longer in BOP custody. | The person may still be on supervision or in another criminal-justice system. |
| Not in BOP Custody | No current BOP institution is shown. | Check U.S. Marshals custody, the federal court docket, state or local custody and supervised-release information. |
BOP inmate, federal detainee or U.S. Marshals prisoner?
“Federal inmate” is often used for several different custody stages. The correct search method depends on where the person is in the federal process.
| Situation | Likely custodian | Where the person may be housed | Best next check |
|---|---|---|---|
| Recently arrested on a federal charge | U.S. Marshals Service after court-ordered detention | Federal, county, regional, local or private contract jail | Federal court docket and the local U.S. Marshals district |
| Awaiting trial | Usually U.S. Marshals Service | Often a non-BOP contract detention facility | Detention order, court district and Marshals office |
| Sentenced but awaiting designation | May remain with the Marshals pending BOP designation and transport | Current detention center until movement | BOP locator periodically and defense counsel |
| Serving a federal sentence | Federal Bureau of Prisons | BOP institution, prison camp, medical center or administrative facility | BOP Inmate Locator |
| Halfway house or community placement | BOP community corrections system | Residential reentry center or approved community placement | Locator status and confirmed community-placement contact |
| Released to supervision | No longer physically in BOP custody | Community residence under federal supervision | Federal court judgment or U.S. Probation information when public |

How to find the correct federal prison or detention facility
| Label | General meaning | Family planning implication |
|---|---|---|
| FPC | Federal Prison Camp, generally minimum security. | Use the camp-specific mail line when a complex has multiple components. |
| FCI | Federal Correctional Institution, often low or medium security. | Confirm whether the person is at the main institution or an attached camp. |
| USP | United States Penitentiary, generally high security. | Visiting, property and communication restrictions can be more controlled. |
| FDC | Federal Detention Center, commonly used for detention and court-related custody. | Court movement can interrupt visits and calls. |
| MCC or MDC | Metropolitan Correctional or Detention Center. | Often serves major federal court districts and pretrial populations. |
| FMC | Federal Medical Center. | Medical placement may affect visiting and communication availability. |
| FCC | Federal Correctional Complex containing multiple institutions. | Use the exact institution and register number, not only the complex name. |
| RRC | Residential Reentry Center, commonly called a halfway house. | Rules differ from secure institutions and the locator may show community-management information. |
What to do after you locate the federal inmate
Match the register number, age, sex, race and known case details before sending funds or personal information.
Open the facility page and check the exact component, phone and inmate-mail address.
Ask about local visiting, mail or emergency-contact procedure rather than requesting protected inmate details.
Wait until physical arrival at a BOP-managed institution and use the centralized deposit instructions.
Use the committed name, register number and facility-specific inmate correspondence address.
Use PACER to review public docket entries, counsel, court orders and sentencing information.
How to visit a federal inmate
There is no single nationwide visiting schedule. The BOP establishes general approval rules, while each institution publishes its own days, hours, point system, dress code details and local procedures.

How to send money to a BOP inmate without using the wrong address
| Method | Information required | Processing detail | Main mistake to avoid |
|---|---|---|---|
| MoneyGram | Eight register-number digits without the hyphen followed immediately by the inmate’s last name; full committed name; receive code 7932. | BOP states that qualifying transfers sent between 7 a.m. and 9 p.m. Eastern are generally posted within two to four hours. | Do not use a nickname or an incorrect account-number format. |
| Western Union | Eight register-number digits without the hyphen followed by last name; full committed name; code city FBOP, DC. | BOP states that qualifying transfers are processed seven days per week, including holidays. | Do not select the individual prison as the company or code city. |
| USPS lockbox | Full committed name and eight-digit register number on the negotiable instrument and envelope. | Money order, U.S. government check, certified or cashier’s check, or bank draft is accepted under BOP rules. | Do not send cash, a personal check, a letter or additional property in the funds envelope. |

How to address mail to a federal inmate
Unlike inmate funds, ordinary correspondence is sent to the institution-specific inmate-mail address. Federal facilities often use a post-office box for inmate letters and a separate physical address for staff, freight or visitors.
Exact institution name or housing component
Institution inmate-mail street or PO Box
City, state and ZIP code
| Mail category | General treatment | Important preparation |
|---|---|---|
| General correspondence | Ordinary letters from family, friends and community contacts are subject to institutional inspection and rules. | Use the exact facility address, committed name and register number. |
| Special mail | Certain properly marked legal, court, government or qualifying official correspondence receives special handling under BOP rules. | The sender and envelope must meet the applicable special-mail requirements. |
| Books and magazines | May be received under BOP publication rules, generally directly from a publisher or authorized source. | Confirm the institution’s current restrictions before ordering. |
| Packages | Usually limited and commonly require prior institution authorization. | Do not send clothing, food, electronics or personal property without written approval. |
| Inmate funds | Processed through electronic services or the centralized federal lockbox. | Never place money or a negotiable instrument inside ordinary inmate correspondence. |
Federal inmate phone calls and TRULINCS email
BOP telephone privileges help inmates maintain family and community ties. Ordinarily the inmate pays, although some arrangements may charge the receiving party.
Approved inmates can exchange monitored text messages with approved contacts. Inmates do not receive general internet access.
Federal phone rules families should understand
- Calls are generally monitored, except qualifying unmonitored attorney communications under applicable procedures.
- Telephone access may be limited by security, discipline, institution operations or account restrictions.
- Third-party call arrangements and prohibited forwarding methods are not permitted.
- A person outside the institution normally cannot call through to an inmate like an ordinary household call.
- Do not share account credentials, payment details or sensitive personal information with an unverified caller.

How to find the federal booking case, detention order and sentence
The BOP locator shows custody information. PACER provides public access to federal court cases, docket entries and filed documents.
| Docket item | What it may tell you | Important limitation |
|---|---|---|
| Initial appearance | When the defendant first appeared before a magistrate judge. | It may not identify the physical jail. |
| Detention hearing | Whether the court considered release or continued detention. | Conditions and later orders can change. |
| Order of detention | The court ordered the person held pending proceedings. | The U.S. Marshals Service decides or arranges the physical detention location. |
| Appearance bond or release order | The court authorized release under stated conditions. | Administrative release may not be immediate. |
| Indictment or information | The formal federal charges filed in court. | A charge is an allegation and does not establish guilt. |
| Judgment | The sentence, imprisonment term, supervision and financial penalties ordered by the court. | BOP calculations and credits determine the operational projected release date. |
| Attorney appearance | The defense counsel or appointed attorney listed in the case. | Counsel cannot disclose protected information without authorization. |
Federal release dates, transfers, halfway houses and home confinement
Why projected dates change
- Federal Time Credit reviews under the First Step Act.
- Good conduct time calculations.
- Retroactive sentencing or court orders.
- Residential Drug Abuse Program sentence-reduction eligibility.
- Compassionate release or reduction-in-sentence orders.
- Parole decisions for eligible older-law cases.
- Concurrent state or federal sentence calculations.
- Detainers or release to another jurisdiction.

How to request additional federal inmate records
The public locator provides a limited set of fields. Additional records may require a Freedom of Information Act or Privacy Act request, and privacy rules can restrict disclosure about another person.
- Name
- BOP register number
- Current age
- Race and sex
- Release date or release status
- Current publicly displayed location
- Historical custody records
- Selected institutional records
- Records about a former inmate
- Records about yourself
- Additional non-public details subject to exemptions
- Older files held by the National Archives
Requesting your own record
BOP says a request about yourself should verify identity and include the full name, current address, date and place of birth and, for a current or former federal inmate, the register number.
Requesting information about another person
Privacy protections and FOIA exemptions can limit what is released. A signed authorization or proof of death may be necessary for records that would otherwise invade personal privacy.
Federal inmate records from before 1982
The online BOP locator is designed for records from 1982 to the present. Many older records were never entered into the modern inmate-management system and have been transferred or are being transferred to the National Archives.
Information to include in an older-record request
Federal inmate search mistakes that waste time or money
A newly detained federal defendant may be in U.S. Marshals custody at a local contract jail.
The name must match the federal record. Use the legal or committed name and try a middle initial.
Mailed BOP funds go to the centralized Des Moines lockbox, not the inmate correspondence address.
Wait for a destination because forwarded federal inmate mail can be delayed or returned.
A visitor must be approved and should reconfirm local visiting operations before departure.
Sentence credits, court decisions, detainers and recalculations can change the displayed date.
Compare the register number, age, race, sex and known federal case information.
PACER can reveal detention orders, counsel, sentencing and court activity that the inmate locator does not show.
Facility-specific questions should be directed to the institution where the person is housed.

Federal jail inmate search and booking FAQs
How do I search for a federal inmate?
Use the official BOP Inmate Locator for federal records from 1982 to the present. Search by register number whenever possible, or use the exact committed name and narrow duplicate results by age, race or sex.
Does the BOP locator show people awaiting federal trial?
Some may appear, but many pretrial detainees are controlled by the U.S. Marshals Service and housed in local, state, private or contract detention facilities.
What does Not in BOP Custody mean?
The person is not presently shown at a BOP institution. They may have been released, transferred, returned to Marshals custody, entered another correctional system or moved to community supervision.
What does In Transit mean?
The inmate has moved from a BOP facility and the destination is not publicly displayed. Wait for a confirmed destination before mailing or planning a visit.
How current is the federal inmate locator?
BOP states that locator information is extracted from its main database and updated daily, but court movement, transfer and release calculations can still create temporary gaps.
Why can I not find the person by name?
The spelling may not match, the person may be in Marshals or local custody, the case may be state rather than federal, or the record may predate 1982.
How do I send money to a BOP inmate?
Wait for physical arrival at a BOP-managed facility. Use MoneyGram, Western Union or an acceptable negotiable instrument mailed through USPS to the centralized Des Moines lockbox.
How do I visit a federal inmate?
Confirm the institution, wait for the inmate to place you on the proposed visitor list, complete approval, and review the institution’s local schedule, ID, dress and property rules.
How do I find the federal criminal case?
Use PACER. Search the specific court when the district and case number are known, or use the PACER Case Locator for a nationwide search.
How do I find federal inmate records from before 1982?
Contact the National Archives with the complete name, date of birth or approximate age, race, approximate incarceration dates and known institution or court district.
