How to Check If Someone Is in ICE Custody: The Detainee Locator, Step by Step

Patrol Blog · 8 November 2026 · Reading time: about 6 minutes

The local case ends, the jail says a transfer happened, and then the phone goes quiet. Learning how to check if someone is in ICE custody starts with one free tool and the right numbers in hand. ICE runs a public locator for exactly this moment. Used right, it tells you whether ICE is holding a person and which facility holds him. Used wrong, it returns a blank page that means far less than it looks like. Keep a notebook open — dates, times, and the exact spelling you searched belong on paper from the first try.

How to check if someone is in ICE custody: start with the locator

The ICE detainee locator — the Online Detainee Locator System, ODLS for short — lives at locator.ice.gov. ICE built it so family members, lawyers, and the public can locate a detained person online, 24 hours a day, in English, Spanish, and seven other languages. The search is free. Any site that asks you to pay to run it is not ICE, whatever its logo looks like.

The locator answers one question: is this person in ICE custody right now, and if so, where? It also lists a person who has been in Customs and Border Protection custody for more than 48 hours. It does not explain why someone was arrested, and it does not carry hearing dates. Custody is one record. The court case is a different record, checked a different way, covered below.

The A-number search: the cleanest way in

ICE recommends the ICE detainee search by A-number whenever the number exists, and the patrol agrees — it cuts through every spelling problem the name search has.

The A-Number, the Alien Registration Number, is the 8- or 9-digit number on paperwork from the Department of Homeland Security or the immigration court: a Notice to Appear, a work permit, a receipt notice. The locator field wants exactly nine digits, so an 8-digit number gets a zero added at the front. Pair it with the person's country of birth — where he was born, not a later citizenship if the two differ — and search.

A hit returns the facility name, its address and phone number, and the Enforcement and Removal Operations office responsible for the case. Screenshot the result with the date and time. Facilities change on transfer, and that screenshot is how you prove where the record stood.

The name search, and why exact means exact

No A-Number? The second door is the biographical search: first name, last name, country of birth, and date of birth.

This search forgives nothing. ICE states it plainly on the locator itself: the names must be an exact match. John Doe will not find Jon Doe, and neither one will find John Doe-Smith. A swapped first and last name or a dropped second surname returns zero records for a person sitting in custody.

Work it like a records clerk. Try the name as it appears on official documents first. Then try it without the hyphen, with the surnames in the other order, with the spelling from an older ID. Log each version. How to find someone detained by ICE is often just this: the right spelling, entered the way ICE entered it.

What the locator cannot show you

Three gaps explain most blank results, and none of them means a person is free.

First, age. The locator cannot search for anyone under 18. Children in immigration custody sit outside this system entirely, so a missing record for a minor tells you nothing either way.

Second, timing. A fresh arrest or a transfer can leave the record behind the person. The National Immigration Law Center warns a name can take more than a day to appear, and a person mid-transfer can drop off until the receiving facility books him in. Search again the next morning before you conclude anything.

Third, custody type. A man still sitting in a county jail on an ICE detainer, waiting for ICE to collect him, is not in ICE custody yet and will not appear. A man held on federal criminal charges sits in Bureau of Prisons custody, which has its own inmate locator. The ODLS covers ICE detention, nothing else.

One newer gap deserves a plain flag. In September 2026, advocates reported that ICE had stopped showing some people with final deportation orders in the locator, and ICE has not explained the change. Treat a blank result for someone under a final order as unconfirmed, not as a release.

When the locator shows nothing

Zero records is a starting point, not an answer. Work the official channels in order.

Call the Detention Reporting and Information Line at 1-888-351-4024, the line for questions about people in ICE custody. Have the full name, date of birth, country of birth, and A-Number if you have it.

Next, contact the ICE Enforcement and Removal Operations field office for the area where the arrest happened. ICE's own guidance points families there when the locator comes up empty. Ask which officer carries the case and write the name down.

Keep the records separate. An ICE check-in appointment is a reporting date for a person ICE is supervising. A locator search is a custody check for a person ICE is holding. Court dates live in a third place: the immigration court's automated case system at acis.eoir.justice.gov, or 1-800-898-7180 by phone.

The caller who charges for a free search

A blank locator result scares families, and tethers farm that fear. The script: a call or message says your relative is in custody, a bond or fee is due at once, and payment by wire, gift card, or cash app keeps him from being moved. Send the money and the voice vanishes.

Real enforcement does not collect fees by phone, and ICE does not charge anybody to search a free public database. Hang up, run the locator yourself, and call the DRIL number you found on ice.gov — never a number the caller handed you.

The officer's beat is set out on the About page. If a fixer is working families around a detention facility or a jail — charging for locator searches, selling bond promises — put the name, number, and script in front of this patrol through report a tether. Patrolling the online borders, one tether at a time.
