How to Find an Inmate at Three-B Juvenile Detention Center

Use the official inmate search link available on this page to check the facility roster or custody information. Jail rosters typically list a person’s name, booking date, charges, and custody status, but juvenile records are often confidential in Idaho, so public information may be limited or unavailable. If a youth was recently booked, processing can take several hours, and records may not appear immediately. Families should contact the facility directly if the online search does not show a result or if the person may be held under juvenile court privacy rules.

FAQs

How do I visit an inmate at Three-B Juvenile Detention Center?

Visitation rules for juveniles are usually more restricted than adult jail visits. Contact the facility before visiting to confirm approved visitor requirements, scheduling, and whether visits are in person or by video.

What do I need to bring when visiting Three-B Juvenile Detention Center?

Visitors are typically required to bring a valid government-issued photo ID. Minors who visit may need to be accompanied by a parent or legal guardian, and all visitors must follow facility dress and conduct rules.

How do I make phone or video calls with an inmate?

Youth in custody are usually allowed approved phone or video contact under facility rules. Calls may need to be scheduled or funded through an approved service, and staff can explain current options.

How do I send mail to an inmate?

Mail should include the youth’s full name and follow the facility’s mailing rules. Do not send prohibited items, and contact the facility first because juvenile mail policies may limit who can send mail and what can be received.

How does the commissary work?

Commissary access for juveniles may be limited and depends on facility policy. If deposits are allowed, staff can explain accepted payment methods, spending limits, and which items may be purchased.

How is bail set and how do I post bond at Three-B Juvenile Detention Center?

Juvenile cases often use court-ordered release conditions rather than the same bail process used in adult criminal cases. A judge or juvenile court officer may decide whether the youth is released to a parent or guardian, kept in detention, or placed under supervision.

What happens during the intake process at Three-B Juvenile Detention Center and when will the inmate appear in the system?

During intake, staff confirm identity, record booking information, review health and safety needs, and assign housing or supervision. Processing can take several hours, and because juvenile records are confidential, the person may not appear in a public online roster.
