Finding Immigration Detainees: Complete Guide
Step-by-step methods to locate loved ones in ICE custody using official tools and backup strategies for families facing uncertainty.
Locating a family member or friend detained by U.S. immigration authorities can feel overwhelming amid emotional distress and urgent timelines. This guide outlines proven steps using official government resources to identify detainees held by Immigration and Customs Enforcement (ICE), Customs and Border Protection (CBP), or other federal facilities, empowering families with actionable information.
Primary Tool: ICE Online Detainee Locator System
The cornerstone for searching adult immigration detainees is the ICE Online Detainee Locator System (ODLS), a free public database accessible 24/7. Available at locator.ice.gov, it lists individuals currently in ICE custody nationwide.
Key features include:
- Real-time status updates showing ‘In Custody’ or ‘Not in Custody’.
- Facility details such as address, phone, and sometimes visitation links upon positive matches.
- Support for over 200 detention centers across the U.S.
Expect delays: New arrests by ICE may take 24+ hours to appear; CBP holds can lag up to 48 hours before transferring to ICE visibility.
Searching by A-Number: Fastest and Most Reliable
The A-Number (Alien Registration Number) is an 8- or 9-digit identifier prefixed by ‘A’ (e.g., A012345678), found on immigration documents like Notices to Appear (NTA), work permits, or court notices. Pair it with the detainee’s exact country of birth for precise results.
Pro tips:
- Pad shorter numbers with leading zeros to reach 9 digits.
- Country of birth must match ICE records exactly—no abbreviations or variations.
- A-Number searches yield higher accuracy than name-based ones, minimizing false negatives.
Searching by Name: When A-Number Is Unavailable
Use full legal name, date of birth, and country of birth. Challenges arise from:
- Exact spelling requirements—no accents, hyphens, or order swaps (e.g., paternal vs. maternal surnames in Hispanic cultures).
- Government entry errors or aliases requiring multiple attempts.

Test variations systematically: first-last, last-first, nicknames, or phonetic spellings. If no results, proceed to backup methods.
What If the Locator Returns No Results?
A ‘Not in Custody’ status doesn’t confirm release—it could indicate transfer, processing delays, or custody by another agency. Never assume freedom without verification.
| Possible Reasons | Action Steps |
|---|---|
| Recent arrest (under 24-48 hours) | Wait and recheck periodically |
| CBP short-term hold | Call CBP at (866) 347-2423 for A-Number |
| Juvenile or victim-based case (T/U visa) | Check specialized facilities or exemptions |
| Criminal charges | Search BOP inmate locator |
Step-by-Step Backup Search Strategies
1. Contact CBP for Initial Arrests
If arrested at the border or interior checkpoints, start with CBP. Provide name, description, and arrest details via (866) 347-2423. Request the A-Number to feed into ODLS.
2. ICE Enforcement and Removal Operations (ERO) Field Offices
Each U.S. region falls under an ICE ERO Field Office overseeing detentions. Locate yours via ICE’s directory and inquire directly—staff can confirm custody even if not yet in ODLS.
Examples by region:
- Atlanta: GA, NC, SC
- Houston: TX gulf coast
- Common transfers occur across state lines within field office jurisdictions.
3. Bureau of Prisons (BOP) for Criminal-Immigration Cases
Since 2025, ICE partners with BOP facilities for overflow or criminal migrant holds. Most appear in ODLS, but direct BOP searches via their inmate locator ensure coverage. Focus on facilities near the arrest location.
Filter BOP lists by ‘Facilities FY25’ tab, state, and gender—ICE uses women-only sites selectively.
4. Immigration Detention Facility Directories
Non-profits like Freedom for Immigrants maintain updated lists of ICE centers, including contact protocols, visitation groups, and gender restrictions. Cross-reference with ODLS results for comprehensive outreach.
5. Consular Assistance
Your home country’s consulate can liaise with U.S. authorities, verify nationality, and provide welfare checks. Search for ‘Consulate General [Country] USA’ and submit detainee details promptly.
After Location: Communication and Support Essentials
Once found, note facility specifics:
- Phone/Visitation: Rules vary—some allow video calls, others in-person with ID checks.
- Funds/Commissary: Deposit via facility portals for phone credits, hygiene, food.
- Mail: Use exact address; monitor for censorship.
Gather documents: A-Number, NTAs, prior filings. These fuel attorney consultations for bond hearings, asylum claims, or deportation defenses—cases escalate rapidly.
Legal Rights and Timelines in Detention
Detainees have rights to counsel (at own expense, though pro bono exists), bond eligibility (mandatory custody exceptions apply), and credible fear interviews for asylum seekers. Timelines tighten: initial hearings within days; appeals demand swift action.
Seek accredited immigration attorneys via AILA.org or non-profits. Public defenders auto-assign for criminal-immigration overlaps.
Frequently Asked Questions (FAQs)
Why doesn’t my loved one’s name appear in the ICE locator?
Common causes include processing delays, name mismatches, non-ICE custody (e.g., CBP, BOP), or exemptions for minors/victims. Retry variations and use backups like field offices.
How long after arrest does someone show in ODLS?
ICE arrests: 24+ hours; CBP transfers: up to 48 hours. Re-check frequently.
Can I visit or send money immediately?
Contact the facility for rules—COVID-era restrictions may persist, with funds via kiosks or online.
What if they’re in a BOP prison?
Use BOP’s locator; federal public defenders handle criminal cases. Most ICE cases still list in ODLS.
Are there gender-specific detention sites?
Yes—ICE’s Excel lists women-only facilities. Non-profits track these.
Preventive Tips for Families
Prepare an ‘immigration emergency kit’: A-Number copies, passports, attorney contacts, power of attorney. Designate a U.S.-based point person for authorities. Apps like Notifica track ICE raids in real-time.
For long-term, pursue status adjustments pre-arrest to avoid detention risks.
