• You must enter the exact spelling of the inmate's FIRST and LAST name.
• If the inmate's name is a common name, you may want to type in their age (as of today) and race to limit the number of results.

ICE Online Detainee Locator System

How to Find Someone in the Immigration and Customs Enforcement (ICE) Detainee Locator

When someone that is not a US Citizen gets arrested in the United States, and they are here illegally, depending on what state or city they are arrested in, the person may be turned over to ICE. 

Many states such as New York and California, as well as hundreds of US cities, have declared themselves 'sanctuary cities' and do not turn over foreigners here illegally, even if they are committing crimes in their jurisdiction.

However, when an alien here illegally is turned over to ICE, and sent to one of the over 100 Immigration Detention Centers in the United States, the only way to try and locate where they are being detained is using the Online Detainee Locator System.

There are two ways to search for an ICE Detainee:

You can look them up using their assigned A-Number.

• An A-Number is a 9-digit number that either looks like this: A-123456789, or like this 123-456-789. This is required if you do not know their name.
  It is also called a Registration Number when on a visa, or a USCIS# when on a Green Card.
  If for whatever reason the A-Number you have does not have 9-digits, you need to add 0s (zeroes) to the front of the number until the number has 9-digits.
  That number might then look like this:  001234567.

You can also try and look them up by using their name.

• In order for this to be effective, you need to have the exact name that is either on their paperwork, or the the name with the exact spelling that they gave ICE. This is required.
• You also need to know the country of their birth, or the country of their birth that they gave ICE. This is required.
• Knowing their Date of Birth is helpful but not required to find them in the system.

Important things to know about using the ICE Detainee Locator

• You do not need to set up an account to use the Detainee Locator System.
• A-Number stands for 'Alien Registration Number'.
• The System does not have information on all detainees in custody.
• Juvenile names are NOT in the System.
• The Detainee Locator System is updated every 8 hours, sometimes sooner.
• If the detainee is being moved to a new facility, the new location will not be shown until they have arrived and are processed. 
• No warnings or prior notice are given in advance of a detainee being moved.
• While being transferred to a different facility they may still be shown online as being in the original facility.
• If you are planning a visit, always call before you come to confirm the detainee is still at the facility and has not been moved.
• To visit a detainee you must have some type of government issued photo ID, or other identification when photo identification is unavailable for religious reasons.
• If you are unable to find the detainee using the System, contact the ICE Office of Enforcement and Removal Operations (ERO) in the area where you believe the person's immigration case was initiated or the Detainee Reporting and Information Line (DRIL) at 888-351-4024.
