What to Know Before You Call Adelanto Detention Center (hours, what to have ready, and limits)
The public phone line at Adelanto Detention Center is open daily from 7:30 a.m. to 3:00 p.m. One thing to know upfront: detainees can't receive incoming calls. You won't be connected directly - instead, you'll leave a message through the facility's phone line.
Call (760) 561-6100 between 7:30 a.m. and 3:00 p.m. daily. This is the same number used to request detainee information and to leave a message for a detainee.
What to Have Ready
- ✓ Full legal name (first and last), including any hyphenated names
- ✓ Any aliases they may use
- ✓ Date of birth
- ✓ Country of birth
- ✓ Detainee’s full name
- ✓ Alien registration number (A-number), if you have it
- ✓ A phone number where you can be reached
Call during public phone hours (7:30 a.m. to 3:00 p.m.) to request detainee information. Need to get a message to someone inside? Use the same number. Have the detainee's full name, alien registration number, and a phone number where you can be reached.
Note: Detainees at Adelanto can’t receive incoming telephone calls. Calling the facility lets you leave a message; it doesn’t connect you directly to the detainee.
Can't get through? Try again during the public phone window (7:30 a.m. to 3:00 p.m.). Before calling back, gather the person's details - full name (including any hyphenated names), aliases, date of birth, and country of birth. This helps staff look them up faster.
