512 Facility Jail Roster Lookup

512 Facility Overview

The 512 Facility is operated by the Maricopa County Sheriff's Office at 2670 South 28th Drive in Phoenix, the same address used for the Intake, Transfer and Release Facility. MCSO describes it as an unclassified temporary holding facility.

Research identifies the 512 Facility as a buffer between ITR and other jail facilities. It is intended to reduce unnecessary transport while detainees are processed, classified, released, or moved into another MCSO building.

512 Facility Capacity and Population

MCSO lists the facility capacity as 512 inmates. The research did not locate a current daily population count for this facility. MCSO says it is designed for short-term stays, usually 72 hours or less but up to five days.

How to Look Up an Inmate at the 512 Facility

Use MCSO Inmate Information for the 512 Facility. Because this is temporary holding, a result may change quickly as the person is released, transferred, or assigned to another jail. The MCSO search requires a booking number or exact name and DOB.

1. Open MCSO Inmate Information and search by booking number if available.
2. Use first name, last name, and DOB in YYYYMMDD format if the booking number is unknown.
3. Confirm whether the current location is the 512 Facility, ITR, or another MCSO jail.
4. If no match appears, call SIMS at 602-876-0322 and check court records, mugshots, VINELink, ADCRR, BOP, or ICE ODLS as needed.

512 Facility Address and Contact

Use the ITR campus address and the MCSO jail information line for short-term holding, transfer, or release questions. The same campus contains multiple custody functions, so exact directions should be confirmed before travel.

Visiting Someone at the 512 Facility

Because the 512 Facility is short-term holding, confirm custody before trying to arrange any visit. MCSO social visitation uses ViaPath/GettingOut remote video, and inspected MCSO material states onsite video visits are currently suspended. Short-term detainees may be moved before a visit can occur.

Mail, Phone, and Money at the 512 Facility

Mail is not routed to the 512 Facility street address for ordinary inmate mail. MCSO uses the Lower Buckeye central mailroom address, and short-term detainees may move before mail is processed. Inmates cannot receive incoming calls; GTL manages outgoing calls.

Verify current rules through MCSO's Information for Families, Visitation, and Inmate Account pages before mailing, visiting, or depositing funds.

Booking and Intake at the 512 Facility

The 512 Facility supports ITR booking, transfer, and release operations. Newly booked or transferring detainees can be held there while still unclassified, usually for 72 hours or less and up to five days according to MCSO research. Classification, medical screening, and movement decisions determine the next custody location.

This short stay changes how a search should be read. A person listed at the 512 Facility may move to Lower Buckeye, Fourth Avenue, Estrella, Watkins, Towers, release, court transport, or another custody system before mail or a visit can be arranged. Use the MCSO search as a current-status check, then call SIMS when timing matters. Do not assume a mugshot, a court docket, or an old booking note proves the person is still in the 512 Facility.

Because detainees are unclassified or in transition, the safest records workflow is narrow and official. Use the booking number when possible, confirm full name and date of birth, check court records for hearing or bond status, and use public-records channels for older booking material not shown online. If the person has been sentenced or transferred, use ADCRR, BOP, ICE ODLS, or VINELink as the research directs.

About the 512 Facility

The facility opened in 2020 and is approximately 67,000 square feet. MCSO says it uses Strategic Inmate Management and direct supervision, including orientation, behavioral expectations, continuous officer-inmate interaction, and medical exam rooms in each housing unit.

The facility is attached to the Intake, Transfer and Release operation, so its public role is tied to movement rather than long-term housing. It acts as a buffer between booking and the rest of the jail system, reducing unnecessary transport while detainees are processed. That role is different from Towers, Watkins, Estrella, Lower Buckeye, and Fourth Avenue, which are described in the research as housing facilities with more defined population groups.

Mail and money should be handled carefully for a short-term detainee. MCSO's ordinary incoming mail route uses the Lower Buckeye central mailroom, while the 512 Facility may only hold a person for a brief period. Inmates cannot receive incoming phone calls, and remote video availability depends on current custody and account rules. Confirm the current MCSO result before using any service that may lag behind a transfer.

The 512 Facility also shows why Maricopa County inmate lookup needs more than a facility name. A person can enter through ITR, spend a short time in the 512 Facility, move to another jail, attend court, post bond, remain held because of another agency, or release from ITR. The same booking number can be useful across those steps, but the current location can change quickly.

For public records, use the record custodian that matches the requested document. MCSO or the county portal is the route for booking and jail records. The Clerk and court portals are the route for filings and hearing records. ADCRR, BOP, or ICE handle later custody if the person leaves MCSO. The 512 Facility should not be treated as a long-term archive for all records tied to an arrest.

The facility's medical exam rooms and direct-supervision model are operational details from MCSO, not a public health-record source. Medical conditions should be reported through the county-linked clinical liaison process when appropriate, while custody confirmation still belongs with MCSO search and SIMS.

Because the 512 Facility is short-term, a prompt search can matter. Checking again after court, bond payment, or transfer may show a different MCSO facility or no county custody at all.
