An Alien Registration Number—also called an A-Number—is a seven-to-nine-digit number assigned to green card holders by the Department of Homeland Security. Typically, nonimmigrants in the United States only temporarily don’t receive Alien Registration Numbers. However, nonimmigrant classes holding employment authorization documents or some other benefits are the exception with an A-Number.
Where Do I Find My Alien Registration Number?
Alien Number on Green Card (Form I-551)
If you were issued a green card/permanent resident card (Form I-551) after May 10, 2010, you’d be able to find your number on the front, next to your picture. The back of the green card also contains the alien number.
Older green cards, issued between 2004 and 2010, have the Alien Registration Number listed as “A#.”
Front of Employment Authorization Document (Work Permit)
If you do not have a permanent resident card but have a work permit (Employment Authorization Document), you can find the Client Registration Number under the USCIS#. It will look something like this: 000-000-001.
Visa Stamp In Passport
Your immigrant visa in your passport—also known as a visa stamp/visa foil—also contains your A-Number. You can locate it on the right-hand side below your case number.
Notice of Action
You may be able to locate your A-Number on some versions of the Notice of Action, Form I-797C, in the field “USCIS#.”
Immigrant Data Summary
You could locate your A-Number on the Immigrant Data Summary, which the U.S. embassy or consulate gave you if you applied for your green card through consular processing at a U.S. embassy or consulate.
Immigrant Fee Handout
Suppose you applied for your green card via consular processing. In that case, you can also find your Alien Registration Number on the USCIS Immigrant Fee handout the immigration officer gave you. Your Alien Registration Number is on the top right-hand side.
Alien Number H1B
Typically, H-1B visa holders don’t get an alien registration number unless they have a green card case processing and have applied for an I-140, Immigrant Petition for Alien Worker. The government would then issue an alien registration number when they approve the H-1B holder’s I-140.

When Will I Get My Alien Registration Number If I’m Applying for a Marriage Green Card?
Marriage green card applicants going through consular processing get their A-Number at the consular interview. If you are already married to your U.S. citizen partner, your Alien Registration Number will arrive roughly 30 days after filing the green card application (I-485). If you are married to a green card holder, you need to wait for your I-130 petition to be approved before you file your I-484 (green card application) and wait for your immigrant visa to become available. Your A-number will be sent to you roughly a year into that process.
What Do I Do If I Lost My Alien Registration Number?
If you can’t find your Alien Registration Number on any USCIS documents or visas, then the Freedom of Information Act system is in place to help you get ahold of your immigration file, which includes the number. Alternatively, you can schedule an InfoPass appointment at your local USCIS office.
Is My A-Number the Same as My USCIS Case Number?
No, these are distinct numbers. Your USCIS case number (also called receipt number) is the one USCIS assigns to your application. The government uses the Alien Registration Number to identify you as a person. The USCIS case number is 13 digits and always starts with three letters and then 10 numbers. Your A-number (seven to nine digits) remains the same across your documents, visas, or green cards. If you apply for a green card and then apply for citizenship later on, the two applications you fill out will have different USCIS case numbers, but the same A-number will be listed. If you see “USCIS#” or “USCIS number” on documentation that doesn’t use the word “case” after it, then you should use your Alien Registration Number in that instance. As you can see, it can get quite confusing, so we highly recommend trusting your immigration case with an experienced attorney.
How Do I Check My Immigration Status?
The receipt number is a unique 13-character identifier that USCIS provides for each application or petition it receives. The agency uses it to identify and track its cases.
The receipt number consists of three letters-for example, EAC, WAC, LIN, SRC, NBC, MSC or IOE-and 10 numbers. You can find it on notices of action USCIS has sent you.
Is My Social Security Number My Alien Registration Number?
No. This is another crucial distinction and can confuse. The Internal Revenue Service and Social Security office use the Social Security Number (SSN) to track a U.S. worker’s taxes, income, and other financial information. When you file your work permit in conjunction with your green card application, you can apply to get an SSN. Those with an SSN should keep it confidential to avoid fraud and unauthorized credit applications.
