BOP Records From 1982
The BOP inmate locator says federal inmate records cover 1982 to the present. It can be searched by name or BOP register number and related federal numbers. BOP also explains that locator data is extracted from its main inmate database and updated daily.
A BOP result showing "Released" or "Not in BOP Custody" means the person is no longer in BOP custody. It does not prove the person has no Alabama court case, state sentence, parole term, county warrant, or immigration custody event. Keep the federal result in its own lane.
| BOP status | Meaning for release research |
|---|---|
| In a BOP facility | Current federal custody, not county jail release |
| Released | Federal custody ended on the listed date |
| Not in BOP Custody | No current BOP custody shown |
| No result | Use federal court, county, ADOC, or ICE path as appropriate |
Search Federal BOP Locator
Use the BOP locator when the facts point to a federal sentence. A Sumter County arrest alone does not make the case federal. The county jail may have held a person for a federal writ, a federal warrant, or a transfer, but the local release record will not show the later BOP discharge date unless the agency recorded a transfer note.
- Search by BOP register number if it is known from federal court records.
- Use name search with age, race, or sex details where available to avoid same-name errors.
- Read the status and release date as federal custody facts only.
- Check federal court records or the county transfer record when the path into BOP is unclear.
The BOP about-records page explains the daily update source and federal scope.

Use the BOP result beside, not instead of, the Sumter County jail and court records.
BOP Is Not Sumter Jail
BOP release dates should not be treated as Sumter County Jail release dates. If a person was arrested locally on a federal matter, held briefly, and then transferred, the county record may show release to another agency. BOP may later show the federal release date. Both records can be true because they describe different custody systems.
Use Sumter County Jail records for the local booking and transfer. Use Sumter County District and Circuit Courts for Alabama case disposition. Use BOP only for federal Bureau of Prisons custody after federal sentencing.
USMS and Federal Holds
The research notes that USMS detainees may be held through jail arrangements or federal detention facilities, but there is not a public general USMS locator equivalent to the BOP sentenced-inmate locator. If the person was held on a federal warrant, writ, or pretrial federal case, use the holding facility, federal court docket, attorney or court notices, and later BOP if a federal sentence was imposed.
For immigration custody after a county release, use ICE Detainee Locator. ICE and BOP are separate systems.
Federal Release Record Chain
A federal release search often needs more than the BOP locator. The county jail record may show a local hold, release to another agency, or transfer. A federal court docket may show the charge, sentence, judgment, and supervised-release terms. BOP shows federal custody status after a person enters the Bureau of Prisons system. Those records form a chain, and each link has a separate owner.
If the BOP locator says "Released," use the listed federal date as the end of BOP custody. If it says "Not in BOP Custody," do not treat that as an Alabama release record. The person may have never entered BOP, may have a state matter, may be in ICE custody, or may have a local court issue. For Sumter County, compare BOP with the jail and court records before describing the release path.
| Source | Release question answered |
|---|---|
| Sumter County Jail | Local booking or transfer date |
| Federal court | Federal charge, sentence, and judgment |
| BOP locator | Federal custody status from 1982 forward |
| ICE ODLS | Current immigration custody, when applicable |
BOP Release Checklist
For a federal release lookup, record the BOP register number, name, age or date of birth if available, status, and release date if shown. Then compare that result with the source that led to the federal path. A Sumter County jail record may only show transfer. A federal judgment may explain the sentence. BOP shows federal custody status after sentence intake.
Do not use BOP to explain Alabama parole, Alabama probation, county jail bond, or ICE custody. Those are separate systems. If BOP has no result but the person was held locally on a federal writ, the federal court docket or holding facility may be the better next source. If BOP shows release, use the release date as the federal custody endpoint only.
BOP Record Boundaries
BOP is a sentenced federal custody locator. It is not the Sumter County Sheriff's Office, an Alabama court, ADOC, ABPP, or ICE. A federal release date may be later than a county transfer date because the person moved through several systems before entering BOP custody. It may also be unrelated to a local Alabama case that remains open.
When a BOP result appears, keep the source label in the notes: federal Bureau of Prisons. Then compare it with the county jail record and any federal court judgment. If the person never reached BOP, the correct source may be USMS-related court paperwork, the holding facility, or the local jail transfer record. BOP answers only the federal custody question.
Sumter Federal Release Notes
For Sumter County users, the main risk is mixing the local jail event with the federal endpoint. A jail record may show a release to another agency, while BOP later shows federal release after sentencing and prison time. Keep both dates if both exist. The county date proves the local custody change. The BOP date proves the federal custody change. If the person was held only on a federal writ and never sentenced to BOP, the locator may not be the right source.
Use the BOP about-records page to confirm the federal database scope and daily update source. Then use the Sumter County court or sheriff record to explain how the person reached federal custody.
