Mark W. Stiles Unit Overview
Mark W. Stiles Unit is operated by the Texas Department of Criminal Justice, not by the Jefferson County Sheriff's Office. The official TDCJ unit page lists the facility at 3060 FM 3514, Beaumont, TX 77705, with phone 409-722-5255. It is a male TDCJ prison unit with custody levels G1 through G5, Security Detention, and Safekeeping. The unit has been ACA accredited since May 2008.
The location in Beaumont causes frequent search confusion. Jefferson County's sheriff roster covers current county jail custody, including pre-trial detainees and county jail holds. Stiles houses sentenced Texas prison inmates and other state custody populations. A person who has moved to Stiles generally will not appear as a current Jefferson County jail inmate unless there is a separate local custody event. For Stiles, the authoritative search path is TDCJ.
Mark W. Stiles Unit Capacity and Population
The research file gives a sourced TDCJ capacity of 3,367 for Mark W. Stiles Unit. That is a unit capacity from the official TDCJ page, not a Jefferson County jail population count. It should not be compared directly with the TCJS county jail figures for the Jefferson County Correctional Facility or Jefferson (P) row because those are separate systems. TDCJ facilities in Jefferson County may house people from anywhere in Texas, not only people arrested in Jefferson County.
The custody range is also a clue that this is a prison page rather than a county jail page. G1 through G5, Security Detention, and Safekeeping are TDCJ unit classifications. Jefferson County jail classifications in the research use different language, including trustee, maximum security, administrative separation, discipline, protective separation, and special conditions. Keeping those terms separate helps prevent an incorrect visit, mail, or money route.
How to Look Up an Inmate at Mark W. Stiles Unit
Use the TDCJ Inmate Search for Mark W. Stiles Unit. The statewide locator searches sentenced Texas prisoners by last name, first name, TDCJ number, or SID number. TDCJ offender information is separate from Jefferson County booking data. It can show state custody details such as unit assignment, offense, sentence, release information, and parole-related dates when available, but it does not show county booking photos, local bond amounts, or Jefferson County warrant fields.
- Open the official TDCJ Inmate Search page.
- Search by TDCJ number or SID number if known, or use last name and first name.
- Review the result for current unit assignment and confirm it says Mark W. Stiles Unit or the relevant TDCJ unit.
- Use TDCJ offender information channels for state custody questions, not the Jefferson County jail roster.
- If the arrest just happened and the person has not been sentenced or transferred, search the sheriff roster first because they may still be in county jail custody.
Mark W. Stiles Unit Address and Contact
Contact the unit or TDCJ for state prison matters. Do not use Jefferson County jail phone lines to confirm Stiles visitation, unit housing, or TDCJ sentence status. The sheriff jail-detail line is useful for county jail custody, but Stiles is a state prison facility with its own TDCJ contact path.

Visiting Someone at Mark W. Stiles Unit
The research file documents that TDCJ visitation rules differ from Jefferson County jail rules. It does not provide a unit-specific Stiles visitation hour table. For accuracy, visitors should use TDCJ's current visitation process and the unit phone number before travel. State prison visitation commonly depends on approval, scheduling, custody level, unit status, and TDCJ rule changes. The Jefferson County jail schedule for Q side, Maximum Security, General Population, Females, and P side is not the Stiles schedule and should not be used for this unit.
| Step | Use This Source | Why It Matters |
|---|---|---|
| Confirm eligibility | TDCJ visitation process | State prison visits use TDCJ approval and scheduling, not county jail appointment rules. |
| Confirm unit status | Mark W. Stiles Unit, 409-722-5255 | Lockdowns, custody level, and housing can affect visits. |
| Confirm location | TDCJ locator | Prisoners can be transferred between units. |
| Avoid county schedule | Jefferson County jail schedule is not applicable | County visitation groups do not control TDCJ prison visitation. |
Mail, Phone, and Money at Mark W. Stiles Unit
The research file does not document Stiles-specific mail, phone, or deposit vendors beyond the key rule that TDCJ procedures differ from county jail procedures. Do not send Stiles personal mail to the Jefferson County MailGuard address in Humble, and do not use Jefferson County Correctional Site ID 164 or Jefferson Downtown Jail Site ID 170 for a TDCJ prisoner. Those site IDs are county jail deposit details. Use TDCJ's current offender information and unit directory resources for prison mail and account rules.
| Service | Correct Frame | Not This |
|---|---|---|
| TDCJ state prison mail rules for the assigned unit | Jefferson County MailGuard jail address | |
| Phone | TDCJ state prison communication rules | County jail SmartInmate assumptions |
| Money | TDCJ inmate trust or current TDCJ deposit process | County jail site IDs 164 or 170 |
| Record requests | TDCJ offender information for state custody | Sheriff records request for current prison location |
Classification at Mark W. Stiles Unit
A Stiles record is not a street-arrest booking record. TDCJ custody begins after court sentencing, transfer, or state correctional classification. The public TDCJ locator can show the TDCJ number, SID number, current unit, offense, sentence or release information, and parole-related dates when available. It does not show Jefferson County booking photos or local bond columns. If a person is state-ready in the Jefferson County jail, they may still appear in county data until transfer. Once assigned to Stiles, the state locator becomes the current public location source.
That distinction matters after a Jefferson County case reaches judgment. The sheriff roster can help with the arrest side of the timeline, but a prison assignment reflects a later state custody stage. Families comparing records should expect differences in vocabulary: bond and warrant fields belong to the county jail phase, while projected release and parole dates belong to the state prison phase.
About Mark W. Stiles Unit
Stiles is one of several TDCJ facilities in the Beaumont area, along with Larry Gist State Jail and Richard P. LeBlanc Unit. Its local presence does not make it a county facility. The distinction is important for families comparing Jefferson County jail search results, court records, and state custody records after sentencing. The county roster may be useful for the original arrest, bond, or booking-photo history, while TDCJ is the system that answers current prison location after transfer.
The research also notes that TDCJ offender information can be reached online and through TDCJ's other offender-information channels. Victim notification in Texas is tied to the TDCJ Integrated Victim Services System and related county notification resources, which are different from a one-time roster search. Use those notification channels when the need is an alert about status or release rather than a single location check.
Note: Confirm location through TDCJ before visiting or sending mail because state prisoners can move between units.
