Based in Mangilao, Guam Adult Correctional Facility is located at #3 Mashburn Lane in Mangilao County, GU. Run by the Guam Department of Corrections, it offers various programs aimed at helping inmates reintegrate into society successfully. From educational to vocational, these initiatives focus on reducing the chances of reoffending. They aim to give inmates the skills they need to thrive once they're back in the community.

While incarcerated, reading is often the best use of time. Please note that books and magazines, puzzles, and word searches ordered for inmates must come directly from the publisher. This policy ensures that the items are new, untampered, and comply with the facility's regulations. Prisons and jails enforce this rule to prevent the introduction of contraband or prohibited materials. By restricting orders to publishers, the facility can better maintain security and control over the content entering the institution. Any books or magazines not received directly from the publisher will be rejected and not delivered to the inmate.

The jail offers a phone program for outbound calls only, with inmates unable to receive incoming calls. Accepting collect calls can be expensive, sometimes exceeding $10 per call. Alternatively, setting up an account through a third-party phone company may entail high fees per minute of usage.

It's important to remember that all phone calls are recorded, and discussing sensitive legal matters over these lines is discouraged.

Inmate Locator

Finding a State Inmate at Guam Adult Correctional Facility

If you're trying to locate someone in Guam state custody at Guam Adult Correctional Facility in Mangilao, the Guam Department of Corrections maintains a state-level inmate locator that covers all DOC facilities. Every state runs its own system, so the search experience differs significantly from federal or county-level locators. If the DOC locator does not return the person you're looking for, call Guam Adult Correctional Facility directly at 671-734-3981 to confirm current custody status.

Using the State DOC Inmate Locator

The Guam DOC inmate locator searches by full name, DOC inmate number, or both. The state inmate number is assigned at intake and stays with the inmate across transfers between facilities within the state, but it does not transfer if the inmate moves to another state or to federal custody. State locators typically return the inmate's current housing facility, custody level, projected release date, and parole eligibility, though specific data fields vary by state.

When the Inmate Doesn't Appear in the DOC Locator

A state inmate may be missing from the DOC locator for several reasons. Newly sentenced inmates often spend weeks at a county jail awaiting transfer to the state reception center, during which they are not yet in the DOC system. Inmates in transit between facilities may be temporarily missing. Some states delay public records by 24 to 72 hours after intake. The InmateAid inmate search can help locate someone during this gap period because it pulls from county jail rosters as well as state systems.

State Inmate Numbers and Out-of-State Transfers

If the inmate was recently transferred from another state under an interstate compact, or moved to federal custody on writ, the Guam DOC locator may show them as "in transit" or remove the record entirely. To track inmates across state or federal jurisdictional moves, call 671-734-3981 for current location and case status.

Once You've Located the Inmate

When you confirm the person is at Guam Adult Correctional Facility, set up an inmate phone account with the facility's contracted provider and arrange any money transfer or commissary funding needed.

Visitation Information

Visiting an Inmate at Guam Adult Correctional Facility

Visiting someone incarcerated at Guam Adult Correctional Facility in Mangilao, Guam means working within the visitation rules set by the Guam Department of Corrections. State prison systems are larger and more bureaucratic than county jails, and visiting procedures, including application forms, approval timelines, and scheduling portals, are standardized across the state's DOC facilities. Before your first visit to Guam Adult Correctional Facility, confirm the current process and your approval status by calling 671-734-3981.

Visitor Application and Approval

Every state DOC requires visitors to submit a written application before being added to an inmate's approved visitor list. The application typically asks for your full legal name, date of birth, Social Security number, address, relationship to the inmate, and your criminal history if any. The DOC runs a background check, and approval can take anywhere from two weeks to a couple of months depending on the state. Prior felony convictions, active warrants, or a recent release from custody yourself can result in denial. You'll receive written notice of approval or denial by mail.

Visiting Days, Hours, and Scheduling

State prisons schedule visits by housing unit, custody level, and day of week. Many state DOCs now require advance scheduling through an online portal such as GTL/ViaPath GettingOut, Securus Visitation, or a state-run system, with visits booked days or weeks ahead. Walk-up visits without an appointment are rare in modern state corrections. Visiting days at Guam Adult Correctional Facility may differ for general population, restricted housing, and protective custody inmates. Call 671-734-3981 for the current schedule and to confirm whether the inmate's current status allows visits.

ID, Dress Code, and Visitor Conduct

Bring a valid government-issued photo ID. Most state DOCs require it to be unexpired and match the name on your approved visitor application. Dress code at Guam Adult Correctional Facility is enforced at the entry point: no clothing matching inmate uniforms (colors vary by state; often blue, white, gray, or orange), no revealing attire, no underwire bras in some facilities (they set off metal detectors), no hats, no jackets in the visiting room. Phones, bags, and electronics stay in your vehicle or in lobby lockers. Searches of visitors are routine; refusing a search ends the visit.

Custody Level and Visit Type

Visits at Guam Adult Correctional Facility depend on the inmate's classification. Minimum and medium custody inmates generally receive contact visits in a common visiting room. Maximum custody, administrative segregation, and protective custody inmates may be restricted to non-contact visits through glass or limited to fewer hours per month. Inmates in disciplinary status can have visits suspended entirely. If the inmate has been transferred recently, has a pending classification change, or is in restricted housing, call 671-734-3981 to verify what type of visit is currently allowed.

Video Visitation

Most state DOCs now offer video visitation as a supplement to or replacement for some in-person visits. Video visits at state facilities are typically handled through GTL/ViaPath, Securus, or HomeWAV and require setting up a paid account, scheduling in advance, and connecting from a smartphone, tablet, or computer. Some states have made video the primary or only visitation option at certain facilities. For information on inmate phone discount plans and money transfer options that work alongside video visitation, see InmateAid's inmate services and call 671-734-3981 to confirm what's offered at Guam Adult Correctional Facility.
