Rio Grande Detention Center Contact Guide: Who to Call and When

For routine questions about someone held at Rio Grande Detention Center, call (956) 615-9720 between 8 a.m. and 4 p.m. This is the general information line families use to ask about detainees. One thing to know: detainees cannot receive incoming calls. So this number is for getting information from the facility, not for speaking directly with the person in custody.

• ✓ First, last, and any hyphenated names
• ✓ Any aliases they may use
• ✓ Date of birth
• ✓ Country of birth

Need to get a time-sensitive message to a detainee? Call (956) 718-4700. This is the urgent-message line. You still won't reach the detainee directly - incoming calls aren't allowed - but staff can deliver an urgent message once you provide the required identifying information.

1. Call (956) 718-4700 - this is the urgent-message number.
2. Provide the detainee’s full name - give the complete name as accurately as possible.
3. Give the alien registration number (A-number) - this helps staff identify the correct person.
4. Leave your own contact details - provide your name and a telephone number where you can be reached.

Calling the main information line? Have the detainee's details ready. You'll need their first and last name (including any hyphens), any aliases, date of birth, and country of birth. Small spelling differences or missing hyphens can slow things down, so double-check what you have before dialing.

The urgent-message line requires more than basic biographical info. Have the detainee's full name and alien registration number ready, plus your own name and a phone number where staff can reach you. That callback number matters - if they need to confirm details, that's how they'll contact you.

Questions about an immigration bond? CeBonds (Cash Electronic Bonds) is ICE's tool for common bond tasks - verifying bond information, posting bonds for eligible detained aliens, and receiving electronic notifications. If you're checking whether a bond has been posted or preparing to post one yourself, start here.

Looking for ways to stay in touch beyond phone calls? Rio Grande Detention Center uses tablets. The detainee has to send you an email invitation first. Once you receive it, you can accept or deny. That invitation opens the door to video visits, email, and text messaging.

Thinking about posting a bond as an obligor? Take time to review the Bond Agreement (Form I-352) first. It's the only document that spells out the bond's terms and conditions - and it's what you're agreeing to when you post. Once you understand what you're signing, CeBonds can help you verify bond information, post a bond for an eligible detainee, and receive electronic notifications.
