What is an Alien Registration Number (A-Number)?

An Alien Registration Number (or A-number) is a unique number essential for tracking your immigration journey, from applying for residency to securing U.S. citizenship. Whether you’re filing a green card application, applying for a work permit, or petitioning for a visa, your A-number plays a crucial role in keeping your paperwork in order.

If you’re navigating the U.S. immigration process, you’ll likely encounter a term that will follow you for life—your Alien Registration Number, often called an A-Number

But what exactly is an A-Number? How do you find it, and why is it so important? Here’s a brief overview of what you need to know.

What is an Alien Registration Number (A-Number)?

Simply put, an Alien Registration Number is your personal identification number within the U.S. immigration system. Issued by the U.S. Citizenship and Immigration Services (USCIS), this number tracks all the immigration-related activities of non-citizens. 

Think of it as a social security number for your immigration status—a way for the government to keep track of your applications, updates, and residency.

Your A-Number is essential when filing most immigration forms, like green cards, work permits, and visas. 

Can I use my visa number as an Alien Registration Number? 

No, a visa number and an A-Number are distinct identifiers. The visa number is used for tracking temporary entries into the U.S., whereas your A-Number is tied to your long-term immigration status.

It’s important to remember that your A-Number is not the same as a USCIS case number or your Social Security Number (SSN). While your case number tracks a specific application, your A-Number stays with you throughout your entire immigration journey.

Who Receives an Alien Registration Number?

Not every visitor to the U.S. will receive an Alien Registration Number. A-Numbers are issued to immigrants who apply for long-term residency or plan to stay permanently. This includes people applying for a green card, family-sponsored visas, or other long-term immigration benefits. Refugees, asylees, and others seeking humanitarian relief also receive A-Numbers.

Are temporary visa holders eligible for an Alien Registration Number?

However, if you’re in the U.S. temporarily on a tourist or business visa, you likely won’t have an A-Number, as you aren’t intending to become a permanent resident. 

That said, there’s an exception: some temporary visa holders, like F-1 students applying for employment authorization under the Optional Practical Training (OPT) program, may receive an A-Number.

Where Can I Find My Alien Registration Number?

So, you know you have an A-Number, but where exactly can you find it? Luckily, it’s prominently displayed on several key immigration documents. Let’s walk through the most common places to look:

  • Employment Authorization Document (EAD): Commonly known as a work permit, your A-Number is usually listed below the "USCIS#" on your card.
  • Permanent Resident Green Card: If your green card was issued after May 10, 2010, your A-Number will be listed as your USCIS#. For older cards, it may appear in a different spot.
  • Immigrant Visa: If you don’t have a green card yet, your A-Number can be found on your immigrant visa stamp, just below the “Registration Number” field.
  • USCIS Notices: Any official correspondence from USCIS, like your Notice of Action (Form I-797C), will usually have your A-Number at the top.

What if I can’t find my A-Number?

Don’t worry, if you’ve applied for immigration benefits before, it’s bound to be on one of these documents. 

A-Numbers vs. USCIS Case Numbers

It’s easy to confuse your A-Number with your USCIS case number since both are listed on your immigration paperwork. However, they serve different purposes. Your A-Number is your personal identification number and stays with you forever. 

On the other hand, your USCIS case number is specific to a single application. If you apply for a green card now and citizenship later, the two applications will have different case numbers, but the same A-Number.

Think of it this way: your A-Number is like your immigration fingerprint—unique and constant. Your case numbers, however, will change with each new application. For more detailed definitions of these terms, check out our immigration legal glossary.

What to Do if You Lose Your A-Number

Fortunately, there’s a process to retrieve your A-Number if you misplaced it. You can submit a Freedom of Information Act (FOIA) request to USCIS to obtain a copy of your immigration file, which will include your A-Number. 

Additionally, you can schedule an appointment with a local USCIS office or seek help from an immigration attorney.

Mirna Sorto

Attentive, thorough, passionate about justice for immigrants, honest and fair – these are some of the words to describe Rozas and Associates law firm. My boyfriend was detained at Winn Correctional Center in Louisiana in June 2019. We hired Rozas to represent him because of their reputation amongst the detainees in the Center. Rachel Chappell and the rest of the Rozas team worked tirelessly to assist us – and he won full asylum one week ago.

Josie Lalonde

Rozas and Associates Law Firm was absolutely amazing handling a case for me. They were very nice and got back to me and whatever I needed. The bond department was on top of everything and managed to get bond for the case. I couldn’t recommend a more better or more reliable group of people to handle immigration cases.

Hannah Castillo

I wanted to apply for my citizenship and Jessica referred me to Rozas and Associates. They made the whole process seem so simple. David and his staff were extremely knowledgeable, not to mention friendly. I highly recommend them for any of your immigration issues.

They are the best immigration lawyers. Thanks to the lawyer Rachel my husband won his asylum. They are more than more than recommended, it was a blessing from God that they represent my husband.

Jaqueline Burgos

For all my Latin friends who are going through immigration and legal processes, I recommend this law firm since they are excellent. They defend the Latino community very well. They are very professional and attentive. They respond to you immediately and fight for your case. A thousand thanks to Pamela for being super attentive and Nancy who was exceptional. Also to John Sharby and his colleagues who worked on my wife's case who was in a Louisiana detention center, they are the best. Many thanks to all for their professionalism.

Aidevis Zamora

We couldn't be more happy about choosing this law-firm. We live in Miami and have a friend that needed help with an immigration case. We did a lot of research and called many different firms and decided to go with Rozas and Associates. From the moment we called, Nancy took the time to explain us everything and what our options were, she was very patient and helpful. Once we decided to hire them, Joseph, David and Rachel were assigned to our case. Rachel is THE BEST! She answered our calls always, and whenever she was busy or not available to talk, she always called us back or texted us... every question that we had throughout the process was professionally and patiently answered by her. She's amazing!!!

Dany Thimann

This law firm is amazing! David represented me in my case and he could not have done a better job. The staff is so professional and friendly. Especially Jessica. They make you feel like your case is the most important one they are working. I plan to recommend them to all of my friends and family who may need their services.

Michelle Barron

I am so very thankful that I found Rozas & Rozas Law Firm. They were so professional and nice. I was blown away with how fast they got me in and was able to help me with my situation.

Thank you Rozas & Rozas. :)

In Louisiana, a no-fault divorce can take between 6 months and a little over a year, depending on child status. In fault-based divorces, the process will take at least 2 years.

If this is the case, hiring a divorce lawyer in Louisiana is highly recommended.

Yes. There are as many divorce laws as there are states. Even neighboring states can have completely different laws than each other. For example, divorce in Louisiana greatly differs from divorce in Texas or Mississippi.
