No BOP Prison in Denton
No Bureau of Prisons institution was identified in Denton County through the official federal facility channels. Facility location is not determined by arrest or conviction county. A person with a federal case connected to Denton may be confined elsewhere, held pretrial for the US Marshals Service in a contracted local bed, transferred into BOP after sentencing, or never enter BOP custody at all.
Denton County Jail records can show a transfer to USMS or another federal authority, but that county movement does not create a BOP record instantly. BOP Locator is most useful after designation to the federal prison system. For federal pretrial detention or a release order, the federal docket and USMS routing are often stronger sources.
Search a Denton Federal Inmate
Open the BOP Inmate Locator. The service covers federal inmates from 1982 to the present. A federal register number is safer than name alone. The locator also accepts DCDC, FBI, or INS numbers and supports a biographical name search.
- Choose number search and enter the known federal identifier when possible.
- Otherwise enter exact first, middle, and last names with age, race, or sex filters.
- Compare the returned register number and demographic fields.
- Read the location or status and displayed release date exactly.
- Record the access date because sentence calculations and statuses can change.
- Check PACER when the person was a federal pretrial defendant or the court terms matter.
- Search the named receiving system if another custodian is indicated.
An old county booking photograph is not enough to identify a federal result. Use full name plus date of birth, register number, case number, or another official identifier.
BOP Denton Release Fields
The federal result table is compact. It should not be expanded beyond its labels.
| BOP field | Use | Limit |
|---|---|---|
| Name | Starts identity comparison | Namesakes require a number or demographics |
| Register number | Controls the federal identity match | Does not replace the case number |
| Age, race, sex | Helps distinguish results | Current values and categories can be limited |
| Release date | Shows BOP's displayed date | Can change after sentence recalculation |
| Location or status | Shows current facility, Released, or Not in BOP Custody | Does not rule out another custodian |
BOP warns that release dates may be recalculated, including under First Step Act changes. Treat a future date as current information rather than a guarantee. After the date passes, check the result again and inspect the federal docket for release and supervision terms.
Read Released BOP Status
A result marked Released or Not in BOP Custody establishes that the person is no longer held by BOP. It does not establish freedom from USMS, ICE, state, county, or municipal custody. It also does not show whether a term of federal supervised release continues in the community.
The pictured BOP released-result view illustrates the federal status fields.

Read the register number, release date, and status together. Then use the case docket or named receiving agency to determine what followed.
- Released
- BOP recorded departure from its custody.
- Not in BOP Custody
- No current BOP facility is shown, without resolving other systems.
- Supervised release
- A court-ordered federal supervision term after incarceration.
- Detainer
- A request or legal basis for another authority to take custody.
BOP Records and Contact
The BOP main public number is 202-307-3198. Online Locator results are the quickest public route. For an older or more detailed federal release history, the BOP Freedom of Information Act page explains the formal request process.
Federal Bureau of Prisons
System: Nationwide federal correctional custody
Main number: 202-307-3198
Online search: BOP Inmate Locator
Historical records: BOP FOIA
Best identifier: Federal register number
A narrow FOIA request should identify the former inmate by full name, date and place of birth where appropriate, register number, and the specific date range. Ask for admission and release history or the release computation needed. Privacy-protected material may require identity proof, consent, authorization, or redaction.
Request a Federal Release Record
Describe existing records instead of asking BOP to explain a case. A focused request might seek the admission date, release date, release status, institution of release, and sentence computation for one register number. Avoid requesting an entire file when the needed issue is a single custody interval.
BOP's online result and FOIA record serve different purposes. The locator gives a fast status snapshot. A responsive agency record can document historical dates and calculations with more context. PACER remains the source for court judgments, detention orders, sentence changes, and supervised-release terms.
Federal privacy law and exemptions can limit disclosure. The agency may redact personal information or require authorization. Preserve the request, acknowledgment, and final response so the provenance of each date remains clear.
USMS Custody Around Denton
The US Marshals Service often holds federal pretrial defendants in contracted state or local facilities and moves them without a public USMS inmate locator. BOP Locator may return nothing because the person has not been designated to BOP. In that situation, search the charging district's federal docket and contact the appropriate USMS district office through official channels.
The PACER Case Locator can identify the federal case and court. Docket entries may show detention, release, bond, sentencing, revocation, or transfer orders. A signed order supplies legal authority, while the holding agency records physical movement.
The pictured official federal case search shows the docket starting point.

A BOP result should not be expected for every USMS detainee. The case and custodian determine the correct path.
ICE After a Denton Transfer
A DCSO movement record may identify immigration custody. Use the ICE Online Detainee Locator with an A-number and country of birth when known, or the exact biographical spelling. Recently transferred people and minors may not appear. ICE publishes the Detention Reporting and Information Line at 1-888-351-4024 with language help.
“Released by DCSO to ICE” means Denton County custody ended, not that the person entered the community. ICE outcomes can include recognizance, immigration bond, an order of supervision, removal, or another transfer. Each has its own record.
| Federal path | Primary source | Question answered |
|---|---|---|
| Designated federal inmate | BOP Locator | BOP location, status, and release date |
| Federal pretrial defendant | PACER and USMS | Detention or release order and custodian |
| Current immigration detention | ICE Locator | Current ICE detention result |
| Historical BOP release | BOP FOIA | Admission, release, and computation records |
Federal Supervision After Release
A BOP release date does not describe the complete federal sentence. The judgment may impose supervised release after incarceration. PACER docket entries can show the original term, later modification, an alleged violation, revocation, or a new custody order. The federal probation office handles supervision under the court's authority.
Do not confuse federal supervised release with Texas parole or Denton County probation. They arise from different sovereigns and records. Likewise, a federal detainer can affect a county or state release without turning that earlier case into a BOP sentence.
When the person also has a Denton County case, use the county booking and court records to document the local stage. Then use the federal register and case numbers to document the federal stage.
Confirm a BOP Release
Start with a matched register number and exact BOP status. Add the federal docket to identify the sentence, release order, or supervision terms. If BOP says Not in BOP Custody, check USMS, ICE, state, or local systems only when the case or movement record points there.
The Denton County released-inmate search explains how the local booking record and destination field create the bridge into federal custody. Keep “release from DCSO,” “transfer to USMS,” “designation to BOP,” “release from BOP,” and “federal supervised release” as separate events.
Note: A BOP release status resolves BOP custody only; preserve the register number, access time, federal case, and any receiving agency.
