BOP Federal Release Scope
The BOP inmate locator is the federal-prison path. It covers federal inmates incarcerated from 1982 to the present. For Tulare County release research, BOP should be used only when the person was charged or sentenced federally, held on a federal writ or USMS matter, or transferred from county custody to a federal system. A county release field may say the person was released to another agency. That is when BOP or federal court records can become relevant.
Do not use BOP as a general Tulare County released-inmate search. The county active inmate search, VINE, sheriff records, and Tulare Superior Court records handle county custody. CDCR handles state-prison custody. ICE handles immigration detention. BOP handles federal custody and federal release dates.
| Custody question | Correct system | Release meaning |
|---|---|---|
| Federal sentence or BOP custody | BOP locator | Federal location or release date |
| Tulare County jail release | Sheriff, VINE, court, records | County time and manner of release |
| State-prison sentence | CDCR CIRIS and BPH | State custody or parole context |
| Immigration transfer | ICE locator and detainer records | ICE custody or recent ICE release path |
Search Federal BOP Release
Use the Federal BOP Inmate Locator when a federal case or custody fact points there. Search by register number when possible. If searching by name, compare age, race, sex, and release information with court or custody records. BOP also warns that release dates may be recalculated because of First Step Act federal time credit changes, so a current date should be checked again if it is important to the timeline.
- Confirm there is a federal case, BOP sentence, USMS transfer, or federal hold.
- Open the BOP locator and search by register number or name.
- Check whether a facility location is listed or only a past release date appears.
- Use the BOP record explanation to interpret past dates correctly.
- Return to Tulare sheriff records for the county release or transfer field if needed.
For a Tulare County arrest that became a federal case, the county record may only show release to another agency. The federal docket and BOP record explain the federal custody period and release date.
BOP Past Release Dates
The BOP record explanation is especially useful for released-first research. BOP says that if the listed release date is in the past and no facility location is shown, the release occurred on that date and the person is no longer in BOP custody. That does not mean no supervision, no state case, no immigration issue, or no county matter. It means the BOP custody event ended.
- BOP custody
- Federal prison custody managed by the Bureau of Prisons.
- Release date
- The date BOP records indicate the person left BOP custody.
- No facility listed
- Often a sign that the person is no longer housed by BOP when paired with a past release date.
- Supervised release
- A federal court supervision term that can follow prison release and is separate from BOP custody.
A BOP release date confirms the BOP custody event, not every state, county, immigration, or supervision issue.
BOP Locator Source
The official BOP inmate locator is the federal custody search source.

Use it only for federal custody. If the person was released from Tulare County jail without a federal custody event, BOP is not the correct record.
The BOP record availability and release-date explanation clarifies how to read a past release date.

That explanation is the key source for the no-facility, past-release-date interpretation.
Tulare Federal Transfer Checks
If a person was held in Tulare County jail on a federal writ or USMS hold, the county release may mean transfer rather than community release. Ask the Tulare records route for the time and manner of release or current holding location. Search federal court records and BOP only when the county record, case history, or family information points to federal custody.
For state-prison commitments, use CDCR. For immigration detainers, use ICE. For probation or PRCS, use Tulare County Probation or CDCR supervision paths. Matching the system to the custody type prevents false conclusions from a no-result search.
Note: A federal BOP release is separate from Tulare County's local jail release record.
BOP Records Chain
A federal release search often needs three records, not one. The Tulare County record can show that local sheriff custody ended or that the person was released to another agency. The federal court record can show the federal charge, sentence, or supervised release term. The BOP locator can show federal custody location or release date. Each source answers a different part of the timeline.
If the BOP locator shows a past release date and no current facility, BOP's own explanation says the BOP custody event ended on that date. That still leaves possible federal supervised release, state custody, immigration custody, or local court obligations. Use the words "not in BOP custody" rather than turning a BOP release into a claim about every other legal status.
When a Tulare County booking was only a temporary hold for USMS or a federal writ, county records may be thin after transfer. Ask for the time and manner of release, the receiving agency, and any current holding location noted in the public record. Then use federal sources to follow the federal case.
The search order should follow the custody order. County jail first for the local booking, federal court for the federal charge or sentence, BOP for federal prison custody, and the federal supervision record if the person has left BOP custody. If the BOP locator has no match, return to the county and court facts before assuming the person was never transferred. The federal system may use different identifiers than the county booking record.
When dates conflict, prefer the source that controlled custody on that date. Tulare County controls the jail release field, while BOP controls the federal custody release date. The federal court docket can help connect those dates when a transfer occurred.
