Federal Prison Release Scope
The Federal Bureau of Prisons holds people designated after federal conviction. A Sullivan County residence, arrest, or local jail stay does not by itself create a BOP record. Federal pretrial detention is generally controlled by the U.S. Marshals Service, often in a state, local, or contract bed. The public BOP locator becomes most useful after designation.
A BOP record can report a current institution, a “Released” status with a date, or that the person is not in BOP custody. Each phrase has limits. “Not in BOP custody” can coexist with USMS, state, local, contract, or ICE custody. The exit from BOP must be matched with the next destination before it is called release to the community.
Search BOP Release Records
The BOP Inmate Locator generally covers federal prisoners from 1982 forward. Identifier search accepts BOP Register, DCDC, FBI, or INS numbers. A name search can use age, race, and sex to narrow results. Use a federal number when known and compare all displayed details.
- Establish that the person had a federal case or BOP designation.
- Search by the strongest federal identifier, or use the exact name and available details.
- Record the register number, age, race, sex, release date, and location or status.
- Compare the date with the federal docket and any named contract facility.
- Check another custodian when the result says released or not in BOP custody but a transfer is possible.

BOP Federal Release Result Fields
Read each BOP result as a federal record. A date may change during sentence review or credit calculation, and a location may identify current custody rather than a release destination.
| Field | Use |
|---|---|
| Name | Starts identity matching but is not sufficient alone. |
| Register number | Provides the stable BOP identifier for records requests. |
| Age, race, and sex | Help distinguish name matches within the public result. |
| Release date | Shows the date label BOP publishes, subject to stated limits. |
| Location or Released status | Describes the BOP result, not every other custody system. |
BOP release statistics distinguish community destinations from transfers to another custodial jurisdiction. That distinction should also govern person-level interpretation. A bare “Released” result does not erase a state detainer or later ICE transfer.
Note: Preserve the search date and exact BOP wording instead of turning “not in custody” into a broader claim.
Why BOP Release Dates Change
BOP warns that some release dates may change while sentences are reviewed and credits are calculated, including First Step Act credit work. A public date should be preserved with its capture date. It should not be promised as a fixed pickup time or treated as proof that all release steps have finished.
A court judgment, sentence computation, disciplinary or credit change, detainer, and transfer can affect the timeline or its interpretation. The public locator provides a useful field, but a detailed calculation belongs to BOP records and the federal court documents. If two dates differ, identify what each source labels and when each was produced.
Actual community release also requires attention to destination. Residential reentry placement, supervised release arrangements, transfer to another sovereign, or immigration custody may follow a prison departure. Use the exact BOP status and the next custodian's admission rather than describing every institution exit the same way.
USMS Pretrial Custody Releases
The U.S. Marshals Service controls federal prisoners from court-ordered pretrial detention through acquittal or release, or delivery to BOP after conviction. Many are held in state, local, or private contract facilities. USMS has no general public person locator equivalent to BOP.
Use the federal court docket, defense or court contacts, the named physical jail, the appropriate USMS district, and a focused inquiry. A local jail can record a USMS pickup while the federal docket records the authority. A later BOP admission can confirm designation. Those timestamps may differ.
USMS public-information policy restricts prisoner photographs and arrival or departure details. Ask only for records and information available through the proper route. A USMS-to-BOP handoff is a transfer within federal custody, not community release.
BOP Release Records and FOIA
BOP's locator is the primary public search. When a historical result is ambiguous or more detail is needed, use the agency's official Freedom of Information Act route. Provide the register number, full name, relevant dates, institution if known, and a precise description of the record.

BOP Freedom of Information Act
A focused request can seek records sufficient to show designation, institution, release date, status, and destination where releasable. Federal FOIA is distinct from Pennsylvania's Right-to-Know process. Sullivan County cannot produce BOP records merely because the case has a local connection.
Keep the request, confirmation, correspondence, response, and any cited withholding basis together. If BOP points to a contract facility or another agency, send that custodian a separate request for its own admission or movement record. One federal office is not required to create a combined timeline from records it does not possess.
Trace a Sullivan Federal Release
Build the timeline by custodian. A Sullivan sheriff entry may show transfer to federal authority. A federal docket may show detention, sentence, or release orders. A contract jail may record physical admission and exit. USMS controls the pretrial stage, while BOP controls a designated sentence. ICE may appear after another federal or local discharge.
| Stage | Best source |
|---|---|
| Local arrest or transport | Sullivan court and sheriff records |
| Federal pretrial detention | Federal docket, USMS, and physical jail |
| BOP designation | BOP number, locator, and institution records |
| BOP release | Locator date plus BOP records and destination |
| Immigration handoff | ICE ODLS and agency records |
The Sullivan County released-person workflow helps identify whether the trail began as county, state, or federal custody. Use no more systems than the record supports.
Federal Release or Transfer
A federal sentence can end with community release, but BOP can also transfer a person to another sovereign. A detainer is a request or legal basis for another authority to take custody. It prevents a simple reading of the BOP exit as freedom from all custody.
- BOP designation
- Assignment of a sentenced federal person to Bureau custody.
- USMS custody
- Federal pretrial or transport custody before acquittal, release, or BOP delivery.
- Released status
- The BOP's published status for its own custody record.
- Detainer
- A hold or notice from another authority that may control the next destination.
If the destination is a state prison, county jail, or ICE, search that system next. If no custodial destination appears, compare the federal court action and BOP record before stating that the person entered the community.
Verify Federal Release Identity
Federal identifiers are crucial. Match the register number whenever possible. A name, age, race, sex, federal docket number, and date of birth can provide additional control. Never merge two records because the names match.
Record the locator search date, the displayed release date, and the current status. Then seek the creating agency's record if the date conflicts with a court entry or another locator. BOP can address its data. USMS can address its stage. A contract jail controls its booking transaction. The court controls its orders.
Older federal custody before 1982 may not appear in the locator's stated coverage. A no-result search is therefore not a universal historical certificate. Use the federal docket, National Archives routes where applicable, or a case-specific agency request based on the known period.
Federal and state numbers are not interchangeable. Preserve the BOP Register number exactly, and note whether another identifier is a DCDC, FBI, or INS number. When a person also has a Sullivan docket or PA DOC number, label each system. This prevents one agency's release date from being attached to a different custody event or a same-name person.
