Check booking and intake timing
A very recent arrest may not appear until identity review, fingerprinting, medical screening, classification, and the agency record are complete.
Retry only the accepted identifiers
Name and supported identifying fields
Check release, transfer, and regional housing
A current-custody service can stop showing a person after release or transfer. Court movement, medical transport, contract housing, or a regional jail can also change the responsible agency.
Use Washington State Department of Corrections only after a state commitment
Open Incarcerated Search after sentencing, admission, or a documented transfer to state corrections. A blank county result alone does not establish state-prison custody.
Use the federal locator only for confirmed federal placement
A local arrest does not automatically create a Federal Bureau of Prisons record. Use the BOP locator after a federal sentence or confirmed BOP placement.
Call the published public contact for urgent confirmation
Call 206-296-1234 and ask King County Department of Adult and Juvenile Detention about the current custody route. Provide the full legal name and any booking, case, or agency identifier you already have.
County jail, state prison, federal custody, and court records are separate
| Situation | Correct starting point | Boundary |
|---|---|---|
| Recent local arrest or local detention | King County Department of Adult and Juvenile Detention — Subject Lookup Tool | Adults currently in custody and people held in King County jails during the supported lookback period |
| Confirmed Washington state sentence or transfer | Washington State Department of Corrections — Incarcerated Search | County jail custody is not included |
| Confirmed federal sentence or BOP placement | Federal Bureau of Prisons locator guide | County and state systems do not replace the BOP locator. |
| Charges, hearing dates, disposition, certified records | Official court case-access or clerk system | An inmate roster is not a complete or certified court docket. |
