BOP Release Lookup

Federal Releases and Yolo Records

BOP says its locator covers federal inmates from 1982 to the present and can show a release date. Research notes BOP's rule for interpreting past dates: if the listed date is in the past and no facility location is indicated, BOP says the person is no longer in BOP custody. That does not prove the person has no other legal restraint, supervision, or custody in another system.

If the question is whether someone left Yolo jail before a federal transfer, use MDC Records or a Sheriff's CPRA request for the county booking and release episode. If the question is whether the person left federal prison, use BOP.

How to Use the BOP Locator

1. Open the BOP Inmate Locator at https://www.bop.gov/inmateloc/.
2. Search by BOP register number if known; otherwise use name and identifying details.
3. Review facility and release-date fields carefully.
4. If the release date is in the past and no facility is listed, treat that as BOP's indication that the person is no longer in BOP custody.
5. Check Yolo court or jail records separately if you need the local arrest, hold, or transfer record.

BOP Records and Contact

BOP also warns that release dates may be recalculated under the First Step Act. When a date appears inconsistent, use BOP records channels rather than Yolo County jail staff unless the question is the local county booking episode.

About Federal Release Records

Federal custody is a separate system. A person can be released from Yolo jail to federal authority, released from BOP to supervision, or still be held elsewhere. The public search needs the right custodian at the right stage: Yolo Records for the county release manner, BOP for federal prison custody, and court records for case outcomes.

Yolo Transfer Versus BOP Release

A Yolo booking can intersect with a federal case in several ways. A person may be arrested locally, held temporarily, transported for court, or released to federal authority. The county record can show that Yolo custody ended, but it does not control the later federal prison release date. BOP controls federal prison custody records after the person is in the federal system.

For a county-to-federal transfer, ask the Sheriff's Records Section for the public release manner and any receiving agency information that can be released. Search the Yolo court record if there was a local case or local hold. Use BOP only for the federal prison custody question. This prevents a county release from being mistaken for a federal discharge and a federal release date from being mistaken for the original Yolo jail event.

BOP Release Date Cautions

BOP notes that release dates can be recalculated under the First Step Act. That means a displayed date should be treated as the federal locator's current public record, not as a promise that every related custody or supervision issue has ended. BOP also states that a person with a past release date and no facility location may still be in another correctional or criminal-justice system or on supervision. For a Yolo-connected person, always ask which system had custody at the time in question.

If the BOP date appears in the past and no facility is shown, that answers the federal prison custody question. It does not answer whether a Yolo case still has court dates, whether local probation exists, whether state custody applies, or whether ICE has separate civil custody. Use the court, county records, CDCR, DAPO, or ICE channels when the facts point away from BOP.

BOP Search Identifiers

The best BOP search uses a federal register number. When that is not available, use full legal name and identifying details, then compare any result carefully. Federal names can overlap. Yolo County context alone is not enough to prove a BOP match. If a local case record or family document has a register number, use that first. If not, compare age, release date, and available federal record details before relying on the result.

BOP Is Not Yolo Roster

The BOP locator should not be used as a substitute for a Yolo jail release record. It will not explain the local booking date, Yolo release time, bail amount, court date, arresting agency, or whether the person left MDC because of an outside hold. Those fields belong to the Sheriff's custody and CPRA routes when they are public. BOP answers the federal prison custody question after the case reaches the federal system.

For a Yolo-connected federal matter, build the record chain in two parts. First, document the local event through MDC Records and the Yolo court record if one exists. Second, document the federal custody period through BOP. If the BOP result says the person is no longer in BOP custody, that answers only the federal part. It does not close every local, state, immigration, or supervision question.

When the search concerns an old federal release, BOP is especially useful because its locator covers federal inmate records from 1982 to present. For an older Yolo jail episode, the county route may require court records or a CPRA request rather than an online release list, since Yolo did not publish a reviewed public recent-release archive.

Keep the federal register number separate from the Yolo case number. Each identifier belongs to a different custodian and record system.

If a Yolo record says transfer to federal custody, use that wording as a bridge to the BOP search rather than as the final release answer.
