What Is an Alien Registration Number and Why Is It Important?

Navigating the U.S. immigration system involves a great deal of paperwork, and one of the most critical pieces of information you will encounter is your Alien Registration Number. This unique identifier is fundamental to your immigration journey, yet many people are unsure what it is or where to find it.

At Hussain, Bendersky & Liston LLC, we provide clear, reliable guidance to help clients manage every detail of their immigration cases. Understanding key identifiers like the A-Number is a crucial first step toward a successful outcome.

Definition and Importance of an A-Number

An Alien Registration Number, often called an “A-Number” or “A#,” is a unique seven, eight, or nine-digit number assigned by the Department of Homeland Security (DHS) to certain noncitizens. Its primary purpose is to serve as a personal file number, allowing U.S. immigration agencies to track an individual’s records across multiple applications and interactions. Think of it as your unique account number within the U.S. immigration system. This number remains with you for life and is essential for filing petitions, checking case status, and proving your immigration history.

Finding Your A-Number

Your A-Number is printed on various official immigration documents. Knowing where to look can save you significant time and prevent stress. You can typically locate your A-Number on the following:

• Permanent Resident Card (Green Card): Labeled as “USCIS#.”
• Employment Authorization Document (EAD Card): Also listed as “USCIS#.”
• Immigrant Visa: Found on the foil placed in your passport, listed as the “Registration Number.”
• Notice of Action (Form I-797C): Included on receipt notices for applications filed with USCIS.
• Other DHS-issued documents, such as those related to asylum or removal proceedings.

Eligibility: Who Gets an A-Number?

Not every individual who enters the United States receives an A-Number. It is specifically assigned to those who apply for, or are placed into, certain immigration processes. For example, an A-Number is typically issued when you:

• Apply for permanent residency (a Green Card).
• Are granted asylum or refugee status.
• Are placed in removal (deportation) proceedings.
• File certain other applications for immigration benefits, such as an application for an EAD.

Visitors on temporary, nonimmigrant visas, like tourists (B-2) or most students (F-1), generally do not have an A-Number unless they begin a process that leads to permanent status.

Lost or Missing Numbers: What to Do

If you have lost the documents containing your A-Number, it is important to take structured steps to retrieve it. You can file a Freedom of Information Act (FOIA) request with U.S. Citizenship and Immigration Services (USCIS) to obtain a copy of your immigration file, which will contain your A-Number. Alternatively, you may be able to schedule an appointment at a local USCIS office for assistance, though this can be a slower process. An experienced attorney can guide you through the most efficient path to recovering this vital information.

How USCIS Uses the A-Number

For USCIS and other immigration agencies, the A-Number is the primary tool for case management. It links all your immigration records—past, present, and future—into a single, consolidated file. When you file a new application, USCIS uses your A-Number to pull up your entire immigration history, ensuring consistency and verifying eligibility. This centralized tracking system is why correctly providing your A-Number on all forms is absolutely essential to avoid delays or complications.
