O.B. Ellis Unit Custody Search

Ellis Unit Inmate Records

TDCJ's Ellis Unit page lists O.B. Ellis Unit as a Correctional Institutions Division prison north of Huntsville in Walker County. The unit is not operated by the Walker County Sheriff's Office. It does not use Walker County Odyssey jail records. Ellis holds male sentenced TDCJ inmates, and TDCJ lists custody levels G1 through G5 plus Security Detention. Those levels cover a wide custody range within state-prison management.

Ellis came online in July 1965 and sits on a large state-prison tract. The research file lists approximate acreage of 11,427. Ellis and Estelle share agricultural operations, including a cotton gin, cow/calf operation, egg laying, farm shop, edible and field crops, security horses, security pack canines, and swine operations. That operations profile is very different from the county jail, which handles local booking, pretrial detention, misdemeanor sentences, warrants, and short-term transfer holds.

For a Walker County inmate search, Ellis should be treated as a state-prison location. A person who was arrested in Walker County may start in the county jail, appear in court, receive a TDCJ sentence, and later be assigned to Ellis or another unit. Once that transfer occurs, the state locator is the correct source for location, offense, and projected release information.

Ellis Unit Capacity

Section 15 reports O.B. Ellis Unit capacity from the official TDCJ unit page. This is not the same as a current daily inmate count, and it should not be mixed with TCJS county jail population totals. The number is still useful because Walker County has one local jail and seven TDCJ prisons. Ellis is one of the larger listed TDCJ capacities in the county research, which helps explain why a Walker County custody search often has to move beyond local jail records.

The combined TDCJ listed capacity in Walker County facilities is 14,435 in the research table. Ellis contributes 2,482 of those beds. By contrast, Walker County Jail's June 1, 2026 TCJS capacity was 268. The two figures answer different questions: county jail capacity describes local custody, while Ellis capacity describes a state-prison institution that receives inmates from the broader Texas system.

Look Up Ellis Unit Inmates

Use the TDCJ Inmate Search for O.B. Ellis Unit. The TDCJ inmate information hub also points readers to online, telephone, and email channels for inmate location, offense, and projected release information. TDCJ's email request route uses pia@tdcj.texas.gov and asks for a full name and seven-digit TDCJ number when available. If that number is not known, the research says to provide an exact date of birth, or an approximate age and county of conviction.

1. Start with TDCJ Inmate Search when the person may be in state-prison custody.
2. Enter a last name and first name, or use the TDCJ number or SID number for a tighter search.
3. Read the location field carefully to confirm Ellis Unit rather than another Huntsville-area unit.
4. Use TDCJ IVSS for offender status details and notification subscriptions.

A new Walker County arrest belongs in the county jail search channel first. A person housed at Ellis has moved into TDCJ custody, so jail roster fields such as local booking status and county bond do not control the state-prison record.

Ellis Unit Contact

Contact the facility for unit-specific questions after the TDCJ locator confirms an Ellis assignment. For statewide inmate-information questions, TDCJ central resources are better because a person can move from one unit to another for classification, medical, program, or security reasons.

Ellis Unit Visitation

Ellis uses TDCJ state-prison visitation procedures. The county jail's NCIC visit schedule, on-site jail visit times, and county video setup rules should not be copied to Ellis. The research file did not capture Ellis-specific visit days, visit length, child-visitor rules, dress-code text, or fee details. Because of that, visitors should check current TDCJ instructions and confirm the inmate's location before travel.

Note: Ellis custody level or unit status may affect visit eligibility, so confirm the visit before leaving for the unit.

Ellis Unit Mail and Money

Use TDCJ rules for Ellis inmate mail, phone access, and money deposits. Walker County Jail mail and money-order instructions are for county custody only. They do not apply to Ellis because Ellis is a state-prison unit. The research did not locate an Ellis-specific fee schedule, so no deposit fee or phone rate should be assumed from local jail pages.

Ellis Unit Programs

Ellis has one of the richer program profiles in the Walker County research. TDCJ lists literacy and GED, special education, CHANGES pre-release, Cognitive Intervention, computer maintenance, Lee College academic and vocational work, cabinetmaking, horticulture, HVAC and refrigeration, peer education, reentry planning, chaplaincy, and GO KIDS. The unit also lists GRAD/RP-GRAD and Champions Youth Program, which give the Ellis page a program emphasis that differs from Byrd's diagnostic intake role and Estelle's medical role.

Operations also distinguish Ellis from other Walker County units. The research notes that Ellis and Estelle share agricultural work such as cotton gin, cow/calf, egg laying, farm shop, crops, security horses, canines, and swine operations. Program availability is not the same as automatic enrollment. It can depend on custody level, eligibility, staffing, space, classification, disciplinary status, and TDCJ placement decisions.

For custody searches, keep program details separate from locator data. A TDCJ search result may show location and sentence information, while education, work, and reentry participation usually must be confirmed through TDCJ channels or the inmate. If the person is still awaiting TDCJ transfer from a county jail, the state-prison program list will not yet determine local jail status.
