How Do You Use the Online Detainee Locator System?

Search the U.S. Department of Homeland Security's Online Detainee Locator System by entering either the detainee's Alien Registration Number or biographical information. The Online Detainee Locator System is available by clicking the Detainee Locator link near the bottom right of the home page.

The search is available in Arabic, English, Spanish, French and Portuguese. Users can also search in Russian, Somali, Vietnamese and Chinese.

To search for a detainee by A-Number, enter the nine-digit number into the relevant box and select the detainee's country of birth from the drop-down menu. The search requires both pieces of information, including all nine digits of the A-Number. Add zeros to the beginning of the A-Number if it does not contain nine digits. An A-Number is assigned to individuals during either enforcement or immigration benefits proceedings.

The detainee's first and last name and country of birth are required to search by biographical Information. The name must match exactly. Further refine the results by entering the detainee's date of birth, although it is optional.

Information about current detainees of the U.S. Immigration and Customs Enforcement agency, as well as detainees released with the previous 60 days, is available on the Online Detainee Locator System. Information about persons under the age of 18 is not available on the system. The database is updated within eight hours of the removal, transfer or release of Immigrations and Customs Enforcement detainees.
