What is Alien Registration (A-Number), and Where Can You Find It?

If you're filling out any USCIS form or trying to check the status of your application, you may be asked about the A-Number, also known as the Alien Registration Number. Remember when I first filled out the I-765 form—it felt like I was being asked for an endless list of numbers, and I was completely overwhelmed. Each form seems to have unique requirements, and trying to keep track of everything can be challenging. For example, on the I-765, you're asked for your Alien Registration Number. But then there are also questions about your USCIS Online Account Number, I-94 Receipt Number, SEVIS, and even Social Security Number, even though you might not have some of them. And yes, you guessed it! Those are not the same numbers! It just adds complexity to already complicated forms. But don't worry! I'm here to help clarify these details for you, just like I wished someone had done for me back then.

What Exactly Is an Alien Registration Number?

Simply put, an Alien Registration Number is a unique identifier assigned to non-U.S. citizens by the Department of Homeland Security.

What are the different names of Alien Registration Number?

The most common names are Alien Registration Number and A-Number, though the USCIS glossary lists also:Alien Number and A#. I'm not sure why the USCIS# is not listed in the official glossary because this is how it is presented by various immigration documents (more about it below).
