The Alien Registration Number can also be referred to as an A-Number. It is a seven-to-nine-digit number that is found on a variety of a United States citizen documents. The A-Number can also be found on Immigration Services (USCIS) documents or the former INS.
USCIS makes use of the A-Number to track immigration files for immigrants and also some nonimmigrants. It is also an important number when processing a new USCIS form to request immigration benefits.

If the Alien Registration Number is less than nine digits, then you can insert a zero after the “A” and before the first digit to make it a nine-digit number. Like for example, “12345678” will then become “A012345678” making it nine digits.
