King County Jail Roster Source
King County adult jail custody is run by the Department of Adult and Juvenile Detention, often shortened to DAJD. The main search tool is the King County DAJD Subject Lookup Tool. County research says the tool can show whether an adult is in custody, the holding location, and the booking number, also called the Book of Arrest or B/A number. That number matters in King County because it is used for mail, deposits, health concerns, and many jail contact tasks.
The King County Sheriff's Office, led by Sheriff Patti Cole-Tindall, remains important for arrests, warrants, transport, and some law-enforcement records. It is not the operator of the adult jail roster. DAJD is the correct agency for KCCF, MRJC, adult jail custody, jail records, visitation, mail, money, and the Subject Lookup Tool.
The Subject Lookup covers adults who have been at King County jails during the last year. It is a custody and booking source, not a proof of guilt source. King County also publishes adult jail booking data through open data, but that dataset warns that names, dates, and charges are not court causes, court cases, criminal filings, criminal history, or criminal status. If charges have been filed in court, the court case system is the better record source.
The roster form can be viewed at the official DAJD public Subject Lookup page.
The form image shows why a broad last-name search can work better than narrowing too soon by facility, race, gender, or custody status.
Use King County Inmate Search
The most reliable search order is broad first, narrow second. King County's own locate-person page says the public lookup should be used to determine current custody and get the B/A number. The jail information phone line remains the fallback when a recent booking has not appeared, when a spelling is uncertain, or when the person may be in a separate city, regional, youth, state, federal, or immigration system.
- Open the DAJD Jail Lookup Service or go straight to Subject Lookup.
- Search by last name. Add first name or date of birth when the name is common.
- Choose Currently In Custody only when the goal is present jail custody at KCCF or MRJC.
- Use Facility only when the holding location is known. The list includes adult jails, juvenile detention, court, community corrections, electronic home detention, and other options.
- Read the result for custody status, location, booking details, and B/A number. If no result appears, call 206-296-1234 for adult jail information.
For youth under 18, do not apply adult roster assumptions. King County gives a 24-hour youth detention and court-date status line at 206-263-9595. For adult booking questions that become court questions, use court portals after the booking search gives the exact name, date, and B/A number.
King County Roster Fields
The King County inmate records form has more filters than a simple name search. Over-filtering can hide a match, especially if the person was moved, booked under a legal name, or listed in a facility category the family did not expect. The captured public form also shows a sign-in link and permission-related messages, but the public Subject Lookup page itself is visible without a login.
| Field Label | Type | Required | Options or Notes |
|---|---|---|---|
| Last Name | Text | Unspecified | Best first search field. No wildcard rule was found in the captured source. |
| First Name | Text | Unspecified | Use to narrow common names after a broad surname search. |
| DOB | Date or text | Unspecified | Date of birth field is visible, but the captured form did not state a format. |
| Race | Dropdown | Unspecified | American Indian, Asian, Black, Hispanic, Other, Unknown, White. |
| Gender | Dropdown | Unspecified | Male, Female, X, Unknown. |
| Facility | Dropdown | Unspecified | KCCF, MRJC, Clark Children and Family Justice Center, King County Court House, Electronic Home Detention, Community Correction Division, and Alternative to Secure Detention. |
| Currently In Custody | Choice | Unspecified | Yes or No. |
| UCN and Preferred Name | Text | Unspecified | Visible under the booking section; the captured source did not expand UCN. |
King County Inmate Record Contents
A King County jail record should be read as a booking and custody record. It can help a family confirm where the person is held, find the number used for mail and deposits, and see practical booking information. It does not settle whether the prosecutor filed the same charge, whether the charge later changed, or whether the person was convicted.
| Field | What It Shows |
|---|---|
| Name | Search and record labels include last name, first name, and preferred name fields. |
| Facility or location | The holding location or custody program, such as KCCF, MRJC, CCFJC, court, electronic home detention, or community corrections. |
| Current custody status | Whether the public result indicates the person is currently in custody. |
| Booking or B/A number | The Book of Arrest number used for contact, mail, money, and many jail follow-up tasks. |
| Booking time or date | The Department of Public Defense says DAJD lookup can show when someone was booked. |
| Investigation or booking charges | Booking allegations or charge labels, not the final court filing or criminal-history result. |
| Bail | Whether bail has been set may appear, but payment and refunds are controlled by jail and court rules. |
| Mugshot | Public display was not confirmed in captured King County sources. Booking photos may require a records request. |
Booking terms are easy to mix up. A remand is a court order sending someone into custody. Classification is the jail process for housing and security level. A detainer is a request or hold from another agency, and it may prevent release even when a bail amount appears.
King County Inmate Access Channels
The full King County inmate records chain is wider than the online roster. If the DAJD Subject Lookup does not find a person, the next source depends on custody type. King County's adult jails are KCCF in Seattle and MRJC in Kent. Kent City Jail and SCORE are separate systems. Washington DOC covers sentenced state prisoners after transfer. BOP covers federal custody, and ICE ODLS covers immigration custody.
- Current adult county jail custody
- Use DAJD Subject Lookup or 206-296-1234 for KCCF and MRJC adult custody and B/A numbers.
- Older or nonpublic jail records
- Use DAJD GovQA records requests and select Incarceration Records for inmate-record requests.
- Municipal or regional custody
- Use SCORE or Kent JILS when a south county city booking is outside DAJD.
- Sentenced state prison custody
- Use Washington DOC Incarcerated Search after felony sentences over 365 days or DOC transfer.
- Federal or immigration custody
- Use BOP for federal custody and ICE ODLS for immigration custody; Washington VINE provides custody notifications.
King County Records Request Fallback
DAJD records are requested through the county records page and GovQA. King County says people seeking inmate records should choose the Incarceration Records tile. Jail operations records use a separate Jail Operations Records tile. Requests can also start by phone at 206-477-5130, by email at records.DAJD@kingcounty.gov, or by mail to Records Request, 500 5th Avenue, Seattle, WA 98104. If a request starts by email, phone, or postal mail, King County says a GovQA account will be created for the requester.
Useful request details include full name, date of birth if known, booking date, B/A number, facility, and the specific record requested. Washington law makes the jail register public, but RCW 70.48.100 and RCW 42.56.240 can allow confidentiality, redaction, or denial for certain records about people in custody, investigations, and victims.
DAJD explains the public-records request process on its official records request page.
The records request page is the practical fallback when a jail roster result is missing, older than the online coverage, or subject to public-record review.
King County Jail Facilities
King County's adult jail system has two DAJD buildings. The King County Correctional Facility is downtown in Seattle, and the Maleng Regional Justice Center is in Kent. The Judge Patricia H. Clark Children and Family Justice Center is a youth detention and juvenile court facility, so adult jail assumptions should not be applied to it. SCORE, Kent City Jail, and FDC SeaTac are separate operators with separate lookup rules.

King County Visits and Contact
After the roster confirms custody, the B/A number drives many family tasks. King County adult jail visits are limited in-person visits, and schedules depend on housing location. KCCF has one-hour weekly visit periods, first-come, first-served, with check-in 15 minutes before the visit. Up to four visitors may visit at one time, and one must be an adult. MRJC uses facility-specific schedules, so call the jail line before travel.
| Facility or Visit Type | Schedule Rule | Key Detail |
|---|---|---|
| KCCF in-person | One-hour visit period each week based on housing location | First-come, first-served. Check in 15 minutes early with government photo ID. |
| MRJC in-person | Facility-specific schedule based on housing | Call 206-296-1234 to verify the current MRJC schedule before travel. |
| Securus video | Up to six free video visits per week | Public visits are monitored and recorded; lawyer video visits are not recorded. |
| Kent City Jail | Visitor application required before visits | Allow at least 72 hours for screening and approval. |
| CCFJC youth detention | Use youth detention contact rules | Call 206-263-9595 for youth detention status and visit routing. |
Phone calls, mail, and money use separate systems. Adults in King County jail get two free calls per week through Securus, regular family mail goes to the Securus Digital Mail Center with the 10-digit booking number, and money deposits use Access Corrections or approved mail and kiosk channels.
The official adult jail visitation page shows the current visit rules and schedule links.
Visiting details are tied to housing and facility operations, so a roster match should be confirmed before travel, deposits, or visit planning.
Note: King County warns about release and Electronic Home Detention scams. Verify payment demands through 206-296-1234 before sending money.
King County State Federal Lookup
A person convicted in King County may leave DAJD custody and become a Washington DOC inmate. Research found no DOC prison physically located in King County, so use the statewide Washington DOC Incarcerated Search for sentenced state custody. DOC searches use DOC number, first name, and last name, and results may show DOC number, name, age, location, and a VINE link.
Federal custody is separate. The BOP Inmate Locator covers federal inmates from 1982 to present by register number or name. FDC SeaTac is a BOP administrative detention center in King County, but it is not a county jail. For immigration custody, use the ICE Online Detainee Locator System. King County research also notes that state law and King County Code restrict DAJD cooperation with federal civil immigration enforcement, so civil immigration custody should not be treated as ordinary county jail custody.
