How do I find out whether someone is at Diamondback?
ICE's locator at ice.gov/locator takes an A-number or exact name, each with country of birth. ICE warns a record can be eight hours old and that not everyone appears, so follow up by phone. For Diamondback that means (888) 351-4024, 8 a.m. to 8 p.m., which CoreCivic's page calls ICE's Detention Reporting and Information Line. Have every name, alias, date and country of birth ready. Being on the ICE facility list proves nothing about one person.
How do I book a family visit at Diamondback?
ICE prints no visiting days or hours for families. Call (580) 614-2100 ext. 42225 to schedule. Each detainee receives two one-hour blocks a week, and any visit counts as a full hour however short it runs. Visits are non-contact. Anyone under 18 needs a parent or guardian, with proof such as a birth certificate or court guardianship order. Bring government photo ID, carry nothing into the visiting area, and leave electronics behind. Everyone passes a pat-down, a bag inspection and a metal scan.
How do I send mail or money to Diamondback?
Letters go to 1000 Diamondback Road, Watonga, OK 73772, with the detainee's name, last 4 digits of the A-number, and your name and address. For money, ICE names ViaPath at 1-888-988-4768 or connectNetwork.com, or a money order mailed to Diamondback Road. CoreCivic's lockbox sheet says otherwise: money orders or cashier's checks, payable to the person, go to P.O. Box 16545, Atlanta, GA 30321-0545, with the commissary number. ICE says the jail refuses cashier's checks by mail. Because these conflict, ask at extension 42225 before mailing money. Never mail cash.
Which immigration court is listed, and how does a lawyer get in?
EOIR's Administrative Control List, updated October 1, 2026, pairs Diamondback with the Aurora Immigration Court in Colorado. That is a records listing and does not settle where a hearing happens, so follow the notice and our hearing lookup guide. ICE's court line is 1-800-898-7180. Lawyers may visit 8 a.m. to 4 p.m. every day, and walk-ins remain permitted. Virtual visits and legal calls go through ERO eFile. For urgent requests ICE gives diamondbacklegal@corecivic.com, and legal mail can go to fax (580) 614-2133.
What are the package, phone and ICE contacts?
Packages need a package approval form and the warden's authorization first. Someone being removed may get one small bag delivered with Supervisory Deportation Officer approval. Tablet messaging is at Talton.com; ICE describes no phone account, so ask at extension 42225, which also takes urgent messages. CoreCivic's only ViaPath sheet is for another prison and uses a site ID, so ask for Diamondback's. The ICE Dallas Field Office is at 8101 N. Stemmons Fwy., Dallas, TX 75247, (972) 367-2200. Dallas.Outreach@ice.dhs.gov takes case questions. For release, read the bond hearing guide. More: Watonga, Oklahoma.
