How do I find my family member at Diamondback Correctional?

Start with the the contracting corrections agency inmate or detainee search - this is the authoritative source for current location and custody status. Private facility records are maintained by the contracting government agency, not by the contracted operator. You can also use InmateAid's inmate locator to search by name across Oklahoma facilities.

If your family member was recently transferred to Diamondback Correctional, allow 24 to 48 hours for records to update before assuming a search result is wrong. You can also pull their arrest record and conviction details to confirm case status. For direct questions, call Diamondback Correctional at 580-614-2000.

Who actually controls the rules here?

This is the question most families do not know to ask - and it matters.

the contracted operator manages the day-to-day operations at Diamondback Correctional: staffing, facility maintenance, food service, and daily scheduling. But the contracted operator does not set the policies that govern your family member's incarceration. Those policies come from the contracting corrections agency, the government agency that contracted the contracted operator to run this facility.

What this means practically: if you have a question about programs, parole eligibility, release dates, sentence credits, or official inmate rights, the answer comes from the contracting corrections agency - not from the contracted operator's main phone line or website. If the contracted operator staff cannot answer a policy question, that is why. Escalate to the contracting corrections agency directly for anything involving official policy or your family member's legal status.

For operational questions - current visiting hours, phone provider, commissary procedures - the Diamondback Correctional facility staff at 580-614-2000 are the right contact.

How do I set up phone calls?

Your family member calls you - you cannot call them. All calls are recorded and monitored except verified attorney calls.

Calls from Diamondback Correctional go through the facility's contracted phone provider. Visit InmateAid's prison calls page to find the current provider and get your account set up before the first call.

Private facilities use the same major phone providers as government-run facilities - GTL, ICSolutions, Securus, or others depending on the contract. The setup process is the same regardless of operator. Do not let it be a barrier.

When can I visit and what are the rules?

Most private facilities require advance visitor registration - contact Diamondback Correctional at 580-614-2000 to confirm the registration process and current visiting hours before making the trip.

Facility Contacts

ICE Supervisory Deportation Officer: 580-614-2000 ext. 42104 Visit and legal scheduling phone: 580-614-2100 ext. 42225 Legal email (exigent or scheduling): diamondbacklegal@corecivic.com Legal fax: 580-614-2133

Visiting Hours

Call 580-614-2100 ext. 42225 to schedule a visit with a detainee.

Each detainee gets two one-hour blocks of visitation per week. Every visit counts as one full block, regardless of how long it actually lasts.

Who Can Visit

Adult visitors (18 or older) can visit unaccompanied with a valid government-issued photo ID.

Anyone under 18 must be accompanied by a parent or legal guardian. You will need to bring proof of the relationship: a birth certificate or a court order showing guardianship.

Visiting Rules

All friend and family visits are non-contact.

No firearms or weapons of any kind. No electronic devices (cell phones, pagers, radios) in secure areas. Visitors cannot pass anything to detainees or carry items into the visitation area.

Every visitor is subject to a pat-down, bag inspection, and metal scan. Refusing a search means you will not be admitted. If you appear intoxicated, you will be turned away.

Attorney Visits

In-person attorney visits run 8 a.m. to 4 p.m. every day.

A list of pro bono legal organizations is posted in every housing unit and updated quarterly. Detainees are responsible for contacting these organizations to schedule appointments.

Virtual Attorney Visits and Legal Calls

Starting March 16, 2026, attorneys must schedule Virtual Attorney Visitation (VAV) appointments and legal calls through ERO eFile. Confirmation comes back through ERO eFile.

Sessions run 8 a.m. to 4 p.m. every day, in 60-minute blocks. Walk-in visits are still permitted. Appointments can be booked up to 2 weeks ahead but no later than 24 hours before the slot, on a first-come basis.

Attorneys are capped at 2 hours of appointments per day. Scheduling more than 2 hours in a single day may result in the additional visits being canceled by the facility.

For a quick phone call, the facility recommends having the detainee call the attorney instead of scheduling an appointment.

The ERO eFile request must include: the attorney's full name and contact info, the detainee's name and A-number (or name, date of birth, and country of birth). For video appointments, provide the Zoom link, meeting ID, and passcode in the Virtual Meeting Information section. For phone appointments, provide the attorney's phone number.

Required attachments: a scan of the attorney's government ID, proof of legal status (bar card, attorney license, paralegal license, or similar), and the eFiled G-28 unless this is a pre-representational visit. If a legal assistant is joining alone, attach a letter of authorization on firm letterhead and a scan of the assistant's ID.

For requests under PBNDS 2011 Section 5.7 (V.N.1) and Section 4.3 (V.FF), upload the written request in the Attorney Authorization Letter field and the Professional Licensure or Curriculum Vitae in the Medical/Mental Health Evaluators field.

Only legal representatives, legal assistants, and interpreters are allowed on these calls. No family, no friends. The attorney can use outside interpretation services during the session. Calls are confidential; an officer stays within sight but out of earshot and will knock 5 minutes before the cutoff.

The facility can cancel or reschedule appointments to manage safety risks or to make sure other attorneys and detainees get fair access. If no slots are available or you have an exigent circumstance, email diamondbacklegal@corecivic.com or call 580-614-2100 ext. 42225.

Legal Mail by Email or Fax

Attorneys can send legal correspondence to diamondbacklegal@corecivic.com or fax to 580-614-2133. Mark "Legal Mail" clearly in the subject line and attach the specific documents to be delivered.

Include a cover sheet with the detainee's full name, A-number, sender's return fax number, total page count, and a "Legal Mail" notation.

Documents are inspected for contraband but not read, then delivered to the detainee. Processing happens during business hours Monday through Friday, 8 a.m. to 4 p.m., excluding holidays.

Consular Visits

Consular officials can meet with their nationals at any time. Call the ICE Supervisory Deportation Officer at 580-614-2000 ext. 42104 to make arrangements when possible, and bring credentials.

How do I put money on their books?

The commissary or trust account gives your family member access to hygiene items, snacks, phone time, and postage. Keeping money on the books is one of the most consistent practical contributions you can make.

Steps to send money to Diamondback Correctional:

1. Go to InmateAid's send money page to find the approved deposit method for this facility

2. Have your family member's full legal name and their ID number - this may be a BOP Register Number, state DOC number, or facility booking number depending on the contract type

3. Choose online deposit, phone deposit, or facility kiosk

4. Use the name and number exactly as they appear in the facility system - errors delay or reject deposits

How do I send letters or photos?

Mail is a consistent connection across what may be a long sentence.

Diamondback Correctional accepts incoming mail addressed to your family member at Route 2, Box 336. Include their full legal name and ID number on every piece of mail. Mail rules at private facilities follow the contracting authority's standards - which means they are typically as strict as government-run facilities of the same type. Plain white paper only, no staples, no glitter, no stickers, no colored ink. Photos should be standard print size with nothing written on the back. When in doubt, keep it simple - rejected mail may not come with notification.

InmateAid's send mail service prints and mails on approved stock from your phone or computer. Formatting rejection is not a risk.

Books and magazines must be ordered new, directly from the publisher or an online retailer. Order through Amazon or directly from the publisher. Anything shipped from a personal address will be rejected.

What programs are available at Diamondback Correctional?

Programs at private facilities are determined by the contract with the contracting corrections agency, not by the contracted operator. The availability of education programs, vocational training, substance abuse treatment, and other programming depends entirely on what the contracting corrections agency has contracted and funded.

Contact Diamondback Correctional at 580-614-2000 or the contracting corrections agency directly to confirm what programs are available and how enrollment works.

How does release work?

Release from Diamondback Correctional is governed by the contracting corrections agency, not by the contracted operator. The operator has no authority over release dates, sentence credits, or early release decisions.

Contact the contracting corrections agency directly for information about release dates, sentence credits, and reentry planning. the contracted operator staff at the facility can answer operational questions but cannot address release timing - that authority rests with the contracting corrections agency.

What are their rights and who do I contact with concerns?

People held at private facilities retain the same constitutional rights as those in government-run facilities. Private operation does not diminish those rights - it just adds a layer to navigating them.

If your family member experiences a problem at Diamondback Correctional - mistreatment, inadequate medical care, safety concerns - the complaint path runs through the contracting corrections agency, not just the contracted operator. the contracted operator has an internal grievance process your family member can initiate, but unresolved complaints should be escalated to the contracting corrections agency's oversight office, the relevant state Attorney General's office, or in serious cases to the federal Department of Justice Civil Rights Division.

Document everything. Private facilities have faced civil rights litigation and oversight investigations - your documentation matters if a complaint escalates. InmateAid's what to expect guide covers inmate rights and the grievance process in general terms. For facility-specific concerns, contact the contracting corrections agency directly.

What else should I know about Oklahoma facilities?

Whether the facility is private or government-run, the experience of having a family member incarcerated in Oklahoma involves navigating the same systems - phone providers, visitation rules, inmate search, and what happens at release. InmateAid's Oklahoma prison resources hub covers all of it in one place, written for families navigating the Oklahoma system.
