El Paso County Jail Annex Overview
The official El Paso County Jail Annex page lists the Annex at 12501 E. Montana Avenue, El Paso, TX 79938, with phone number 915-856-4802. It is operated by the El Paso County Sheriff's Office Detention Bureau. The Annex is not a state prison, even though it sits near other correctional and detention facilities on the Montana Avenue corridor. It is a county jail annex and uses county jail lookup channels.
The Sheriff's Office page gives the Annex a 1,450-bed count. Research also shows that TCJS reports El Paso County countywide jail capacity as 2,976 beds in the June 2026 current population workbook. That TCJS number is a regulatory countywide jail figure and should not be treated as the Annex's building capacity. The Annex page should therefore use the Sheriff's 1,450-bed figure for the facility and the TCJS figure only when explaining the whole county jail system.
People held at the Annex are part of the local jail population: pretrial felony and misdemeanor detainees, local convicted misdemeanants, people held on bench warrants, parole violators, state-jail felony detainees awaiting case outcomes or transfer, and other county jail classifications reported at the system level. Sentenced TDCJ inmates assigned to Rogelio Sanchez State Jail are not Annex inmates.
The screenshot below is tied to the official Jail Annex facility page in the manifest and supports the address, phone, and bed-count discussion for the Annex.
Use that official facility page for building-level facts. Use the county JailRecords module for inmate lookup, because the facility page itself is not the roster.
El Paso County Jail Annex Capacity and Population
The facility-specific number documented for the Jail Annex is 1,450 beds from the Sheriff's Office facility description. TCJS reports the total El Paso County jail system at 2,976 beds, with 2,311 people held on June 1, 2026. TCJS also reported an average daily population of 1,890 for the county row on that date in the incarceration-rate workbook. These are countywide reporting numbers, not a live Annex housing count.
Countywide figures are useful for understanding scale, but they do not identify whether a particular inmate is housed at the Annex today. Housing assignment can shift for classification, medical, security, transport, court, or operational reasons. Confirm a current assignment through the jail search and facility phone before scheduling a visit.
How to Look Up an Inmate at El Paso County Jail Annex
Start with the El Paso County Public Case Search JailRecords module. The Jail Annex is a county jail facility, so the same county jail record search covers Annex inmates and Downtown Detention Facility inmates when they are in local Sheriff's Office custody. Do not use the TDCJ locator unless the person has already moved to sentenced state custody.
The county jail form has two search modes. Defendant mode requires Last Name and First Name and allows Middle Name, Date of Birth, and booking-date filters. Booking Number mode requires the booking number. Search execution requires Cloudflare Turnstile, and the county's public notice says the information is made available as a public service without a warranty of accuracy, reliability, or completeness.
- Open the county JailRecords page.
- Search by Defendant when only a name is known.
- Use Booking Number mode for paperwork that already lists a booking number.
- Compare any custody result with the facility name or contact the Annex if housing is unclear.
- If the person has been sentenced or transferred, search TDCJ, BOP, ICE ODLS, or VINELink as appropriate.
The county's related Public Case Search modules can also matter. Jail Bond Records is separate from Jail Records, Criminal Case Search is for court filings after arrest, and Warrant Search is a separate active-warrant tool. A complete picture may require more than one module.
El Paso County Jail Annex Address and Contact
The Jail Annex is on the Montana Avenue corridor, where several detention and correctional facilities are close enough to confuse visitors. The address and phone below are for the county jail annex. Rogelio Sanchez State Jail, the ICE facilities, and the federal prison use different agencies, rules, and search systems.
El Paso County Jail Annex
12501 E. Montana Avenue
El Paso, TX 79938
915-856-4802
Call ahead for current custody, visitor eligibility, and entry instructions.
When online search results do not answer a records question, use the Sheriff's Crime Records page for public-information routing. For formal court case status after filing, use the county Criminal Case Search module instead of asking the Annex to act as the court clerk.
Visiting Someone at El Paso County Jail Annex
Visitation at the Annex is county jail visitation. The research did not capture an official day-by-day Annex social visitation schedule, visitor fee table, or complete video visitation instructions. It did capture that county jail pages point users toward visitation rules, ViaPath phone instructions, and commissary topics. Because hours and vendor rules can change, visitors should confirm the schedule directly with the Annex before driving to Montana Avenue.
| Visit Topic | Current Research | Action |
|---|---|---|
| Social visitation hours | Not fully captured in official text | Call 915-856-4802 before scheduling or traveling. |
| Visitor list and ID | Rules must be confirmed through Sheriff's sources | Bring government-issued photo ID and follow jail screening. |
| Attorney visits | Handled separately from social visiting | Confirm professional access with the facility. |
| Remote visits | Provider and rates not fully documented in the research | Do not rely on third-party fee claims without official confirmation. |
Any visitor should treat the Annex as a secure jail environment. Arrive with only necessary identification and approved items, allow time for screening, and verify that the person is still assigned to the facility before making the trip.
Mail, Phone, and Money at El Paso County Jail Annex
Mail and commissary for the Annex should be handled through current Sheriff's Office jail rules. The research did not locate a complete official mailing format, current scanned-mail vendor, money-deposit fee table, iCare or package confirmation, or detailed phone-rate schedule. It did confirm that county pages reference phone instructions and commissary, and that jail programming includes education, religious services, life skills, recovery programming, and reentry services where available.
| Service | Use This Source | Research Gap Preserved |
|---|---|---|
| Current Sheriff's jail mail rules and facility instructions | No exact public address format was captured for publication. | |
| Phone | County references to ViaPath phone instructions | No official rate schedule was captured. |
| Money or commissary | Official Sheriff's commissary routing | No fee table or deposit limit was captured. |
| Programs | Sheriff's Programs and Services page | Public program list does not guarantee individual eligibility. |
Booking, Housing, and Transfers at El Paso County Jail Annex
A person may be booked into the county jail system and later assigned to the Annex based on classification, housing availability, court movement, medical or security needs, or other jail decisions. The county public search proves the existence of name, booking number, date of birth, and booked-date search fields, but it does not publish a live housing plan for every unit in the captured research.
If a person was arrested recently and does not appear online, check again after intake has had time to process or call the appropriate facility number. If the person appeared in the county jail search and then disappears, consider release, transfer to TDCJ after sentencing, federal custody, immigration transfer, a name or date mismatch, or record-access limits.
About El Paso County Jail Annex
The Jail Annex is a major county jail building, but it is only one part of El Paso County's custody landscape. The Downtown Detention Facility is the primary downtown county jail. Rogelio Sanchez State Jail is TDCJ custody. FCI La Tuna is Federal Bureau of Prisons custody. El Paso Service Processing Center and ERO El Paso Camp East Montana are ICE civil immigration detention facilities.
That mix makes accurate routing important. For the Jail Annex, use the county JailRecords module and facility phone. For sentenced state custody, use TDCJ. For federal sentenced custody, use BOP. For immigration detention, use ICE ODLS. VINELink may help with notifications, but it does not replace the official source for jail booking records or court records.
Note: Confirm the person's current housing assignment and the latest Annex visitation instructions before traveling or sending funds.
