Your Alien Registration Number, also known as an A#, is a unique nine-digit number assigned by the U.S. Department of Homeland Security to immigrants as part of the U.S. Immigration System. Your A# is distinct and can typically be found on immigration documents associated with your case, such as your Notice to Appear (NTA) or Order of Release on Recognizance.

You can refer to our compiled addresses of ICE Attorney's Offices linked to each immigration court. Note that in the list, these offices are sometimes listed as DHS Office of the Chief Counsel, which is the official title for the ICE Attorney's Office.
