Facility quick reference

How to locate or contact a detainee

To locate someone in ICE custody, use the ICE Online Detainee Locator System at locator.ice.gov. You will need the person’s A-number (Alien Registration Number) and country of birth, or their full name, country of birth, and date of birth.

To ask whether someone is held here, and to leave an urgent message for a detainee, ICE publishes one number: (928) 627-2101. ICE lists it as answered between 8 a.m. and 4 p.m. for detainee information. For a message, leave the detainee’s full name and alien registration number (A-number), plus your own name and a phone number where you can be reached; the facility passes the message on. Detainees cannot receive incoming calls — they place outgoing calls themselves. Have the person’s biographical information ready when you call (first, last and hyphenated names, any aliases, date of birth, and country of birth). ICE says this facility does not have tablets, so there is no electronic messaging route: ICE lists the phone message and postal mail instead.

Visiting in person

ICE’s page for this facility (last updated 08/06/2026, checked September 24, 2026) splits social visiting days by sex:

• Call 24 hours in advance to schedule the visit. ICE’s page gives no separate scheduling number; the only facility number it lists is (928) 627-2101.
• All family and social visits are non-contact. Visitors may not pass items to detainees or carry items into the visitation area, and anyone who is or appears to be intoxicated is refused.
• Everyone entering the facility or the visitation area is subject to a pat-down search, an inspection of belongings and a metal scan, and no electronic devices (cell phones, pagers, radios) are allowed in the secure areas.

ICE lists free public parking at the facility.

Sending mail, commissary funds, and personal items

Letters and packages sent to a detainee must identify the detainee and show the sender’s name and return address (this facility’s own format is below) — and each facility publishes its own exact format: some also require a housing-unit number, and facilities run by the federal Bureau of Prisons use the BOP register number instead. ICE lists each facility’s format on that facility’s page at ice.gov. This facility’s own ICE page says incoming mail “is not read upon opening, only inspected by the delivering officer” and that detainees may seal their own outgoing letters. ICE’s national standard allows more than that. Under ICE’s National Detention Standards, Revised 2019, §5.1(E), incoming general mail is opened and inspected for contraband, and outgoing general mail may be inspected and read if it is addressed to another detainee or staff have reason to believe it threatens the facility’s security or order, endangers someone, or could facilitate criminal activity. Only special correspondence — mail to or from attorneys and other legal representatives, courts and judges, government attorneys, embassies and consulates, the President and Vice President of the United States, members of Congress, the Department of Justice (including the immigration courts), DHS (including ICE/ERO, IHSC, CRCL and the DHS Inspector General), grievance administrators, and the news media — may not be read or copied by staff. Incoming special correspondence is inspected for contraband in the detainee’s presence; outgoing special correspondence is not opened, inspected or read, and if a need exists, any inspection takes place in the detainee’s presence. The standard limits any inspection to detecting physical contraband and confirming that enclosures qualify as special correspondence. Mail counts as special correspondence only if the envelope unambiguously identifies the title and office of the sender (incoming mail) or of the addressee (outgoing mail). Rules for commissary (account) deposits and permitted personal items vary by facility, and so does the number that handles them — ICE names a separate facility mail clerk on some facility pages. This facility’s deposit route, accepted form of payment and contacts are in the Sending Items to Detainees section of its own ICE page (linked above).

What ICE publishes for this facility’s mail, money, and packages

• Mail goes to a P.O. box, not to the street address. ICE’s format:

Detainee Name, A-Number
San Luis Regional Detention and Support Center
P.O. Box 7710
San Luis, AZ 85349

Letters must include the last four digits of the detainee’s A-number (File Number), plus the sender’s name and address. Outgoing mail is routed to the post office within 24 hours of receipt by facility staff.

• Money: as of September 24, 2026, ICE’s page for this facility names no deposit method, vendor or address for money. It says only that funds received in the mail are taken to processing, put on the account and receipted, and it cautions detainees not to have cash sent in the mail. Ask the facility at (928) 627-2101 how to send funds before mailing anything.
• Packages: before sending one, contact the Facility Warden:

San Luis Regional Detention Center
Attn: Warden
406 N. Avenue D
San Luis, Arizona 85349

Items are limited to those needed solely for travel or release from custody, with the ICE Deportation Officer’s approval.

• Stamps: detainees may buy them; indigent detainees get a postage allowance at government expense.
• Transfers and departures: only legal mail is forwarded; general correspondence is returned to sender.
• Luggage for removal: one small piece is allowed; if the person has none, luggage can be sent or delivered after approval from the Supervisory Deportation Officer. No electronic devices are accepted.

Legal access, attorneys, and immigration court information

Detainees have the right to speak with an attorney, and attorney–client visits and calls are confidential. For information about a case before the immigration court (EOIR), EOIR’s automated line 1-800-898-7180 (toll-free, 24 hours a day, English and Spanish) gives the next hearing date and case status; callers enter the 9 digits of the A-number, without the letter A (EOIR, checked October 24, 2026). For a matter before the Board of Immigration Appeals (BIA), the main line of EOIR (the Justice Department agency the BIA belongs to) is (703) 305-0289. Applications for relief from removal must be filed directly with the immigration court handling the case. If you cannot afford an attorney, the immigration court can provide a list of pro bono legal service providers — see the related resources below.

Case information, the deportation officer, and G-28s

• Case-information requests for people held here go to Deportations.ECC@ice.dhs.gov. ICE notes this mailbox does not accept applications for a stay of removal or case appeals.
• To learn who the client’s Deportation Officer is, ICE directs representatives to the San Diego Field Office – Calexico, CA Sub-Office at (760) 768-6300; a G-28 must be on file before anything is disclosed.
• G-28s can be submitted through ERO eFile. Facility staff do not have access to it, so bring a downloaded copy of the submitted G-28 to any in-person or remote legal visit.

Booking video and phone legal visits by email

At this facility, ICE says video teleconference (VTC) meetings and confidential legal phone calls are requested by email to SLDC-Legal_visits@lasallecorrections.com; the facility receptionist replies with a confirmed date and time.

• The email should include the representative’s full name and contact details (phone and email), the detainee’s name and A-number, a few proposed dates and times, and the preferred video application (Microsoft Teams, Zoom, Cisco WebEx or Skype) with its meeting ID or name. Attach a scan of the representative’s government-issued ID, proof of active legal-representative status (such as a state bar card), and the DHS Form G-28 unless the visit is pre-representational; a legal assistant joining alone also needs a letter of authorization on letterhead and a scan of the assistant’s ID.
• Requests should be made 24 hours before the desired time. Appointments run 8 a.m. to 8 p.m. in 30- to 60-minute increments (more time can be requested, depending on availability). ICE’s page says legal representatives are not limited on the number of virtual appointments they can request, but no more than one 60-minute appointment with a detainee per day.
• Only legal representatives, legal assistants and interpreters may attend. A visitation officer stays outside the room, out of earshot but within eyeshot, and knocks 5 minutes before the cut-off time.

Faxing legal documents to a detained client

When timely communication through the mail is not possible, the facility administrator may, in his or her discretion, allow for a reasonable amount of communication between the legal representative and their detained alien client. ICE lists two fax numbers for legal paperwork: (928) 627-1057 and (928) 627-1175. The cover sheet must give the sender’s name, the law office’s name and address, the detainee’s name and identification number, the sender’s return fax number, the number of pages and the date. Incoming faxes are placed in a sealed envelope with the detainee’s name and A-number on the outside, inspected for contraband but not read, and delivered. They are processed during normal business hours, Monday through Friday, excluding holidays; staff keep the fax transmission verification report and give the detainee a copy.

Feedback, complaints, and oversight

To report a concern about conditions at this facility or the conduct of an ICE or contract employee, contact the ERO San Diego Field Office that oversees this facility, or file a complaint with the DHS Office for Civil Rights and Civil Liberties (CRCL). On its own Make a Civil Rights Complaint page DHS publishes one channel — the online portal at engage.dhs.gov/crcl-complaint; CBP additionally publishes, for the same office, the e-mail address CRCL@dhs.gov, fax (202) 401-4708, and the postal address DHS/CRCL, Compliance Branch, 2707 Martin Luther King Jr Ave SE, Mail Stop #0190, Washington, DC 20528-0190. The DHS Office of Inspector General (OIG) hotline is 1-800-323-8603.

This facility’s own ICE page adds these channels:

A news reporter who wants to interview someone held here must apply in writing to the San Diego Field Office. ICE says a detainee has the right not to be interviewed, photographed or recorded, and the reporter must first obtain the detainee’s written permission.

ICE inspection record

ICE’s Office of Detention Oversight (ODO), part of ICE’s Office of Professional Responsibility, inspected this facility on January 26–30, 2026 (ODO report, Inspection 2026-001-070). ODO notes that it conducted a contingency inspection instead of the on-site inspection because of inclement weather. What the report says:

• Who runs it: the facility opened in 2007, is owned by the City of San Luis and is operated by LaSalle Corrections. ICE began housing detainees there in 2011 under ERO San Diego. It is a non-dedicated ICE facility operating under the National Detention Standards (NDS) 2019, and it holds male and female detainees of low and medium-low security classification for periods longer than 72 hours.
• Staffing and services: ERO has deportation officers assigned full time, on site Monday through Friday, 8 a.m. to 4 p.m. LaSalle Corrections provides food and medical care, and Correct Commissary Services provides commissary. The facility was certified under the DHS Prison Rape Elimination Act (PREA) standards after a February 2023 audit, and under the Department of Justice PREA standards after an April 2022 audit.
• Findings: compliant with all 24 standards reviewed; no deficiencies.
• Detainee interviews: ODO interviewed 12 detainees; none alleged discrimination, mistreatment or abuse, and all reported satisfaction with facility services.
• Rating: Superior. ODO’s previous full inspection, in fiscal year 2024, found 1 deficient standard with 2 deficiencies (Food Service) and was also rated Superior.

ODO redacts bed-capacity and population counts in the published report; for population, see the ICE statistics box above. ICE lists every posted report for this facility on its ODO facility inspections page.

Earlier inspections.
