A Number: What It Means and Why It Matters in Immigration Law

Definition & Meaning

An A number, or alien registration number, is a unique identifier assigned to individuals who are not U.S. citizens but are in the country legally. This alphanumeric code is issued by the Department of Homeland Security (DHS) and typically consists of an "A" followed by either eight or nine digits. For example, an A number may look like "A12345678" or "A123456789." It is essential for tracking immigration cases and maintaining records of non-citizens in the U.S.
