How to Find Someone Detained (what to gather before you call or search)

Start with the detainee’s first and last name, exactly as they use it legally. Even small differences can slow things down, so write it out carefully and think through any spelling variations you’ve seen on documents (including hyphenated last names). If you’re unsure, jot down the most likely versions so you can try them consistently when you search or when someone asks you over the phone.

Next, have their country of birth ready. This is one of the main details used alongside a name, and it helps separate your loved one from someone else with a similar name in the system. If you only have time to gather one extra item beyond the name, make it this.

If you can find it, the Alien Registration Number (A-Number) is the most useful identifier to have. It’s a unique identification number assigned to a non-citizen, and it can be a seven-, eight-, or nine-digit number. When you have the A-Number, you’re less likely to get stuck sorting through similar names.

CFIA’s detainee search is built around the basics: the detainee’s first and last name and their country of birth. Enter the name carefully, and if your first attempt doesn’t return results, try the spelling variations you wrote down (especially if the person uses a hyphenated last name or has multiple last names).

If you have the detainee’s A-Number, use it. Because the A-Number is a unique ID (seven, eight, or nine digits), it can cut through confusion when multiple people share similar names.

If the online search comes back empty, or you need confirmation about whether someone is in ICE custody, call the ICE ERO Information Line at 888-351-4024. Have the name and country of birth in front of you (and the A-Number if you have it), and ask directly whether they can confirm custody status and what the next step is if the person doesn’t appear in a search.

1. Call CFIA for help running the search - Reach CFIA at (844) 910-2342 and be ready to share the detainee’s first and last name, country of birth, and A-Number if you have it.
2. Double-check the details you’re using - Make sure you’re using the full legal name and the correct country of birth, then try any spelling variations you know.
3. Keep your notes together for follow-ups - If you need to call back, having the same details and a clear record of what you tried will make the next conversation faster.

• ✓ Any paperwork that might list an A-Number (a seven-, eight-, or nine-digit Alien Registration Number)
• ✓ Any notices or documents you received that include identifying numbers tied to the person

While you’re searching and calling, keep a simple log: who you contacted, the date/time, the spelling and country of birth you used, and what you were told. If you later need help from an advocate or attorney, having the A-Number (if you find it) and a clear record of your attempts can prevent you from starting over each time.
