Tryalma Launches Educational Resource on Alien Numbers for Immigrants in the U.S.

June 02, 2025 at 17:26 PM EDT

If you've recently received your green card, or are in the process of getting one, you might have noticed a mysterious number on it—the "Alien Number" or "A-Number." While it might sound a bit intimidating, the Alien Number is actually an essential part of your immigration journey in the United States. This number helps the U.S. government track your immigration status and history.

Here, we’ll break down everything you need to know about your Alien Number, why it’s important, where to find it, and how to use it throughout your time in the U.S.

What is an Alien Number?

The Alien Number, also called the "A-Number," is a unique number assigned to you by the U.S. Citizenship and Immigration Services (USCIS). It is a 7-9 digit number used to identify you in the U.S. immigration system. This number helps USCIS keep track of your records and any changes to your immigration status, such as applying for a Green Card, renewing your status, or applying for U.S. citizenship.

Simply put, it’s like an ID number for all your immigration-related activities.

Where Can You Find Your Alien Number?

You can easily find your Alien Number on your Green Card. Look for the number labeled "A#"—that’s your Alien Number. It will be located on the front of your card, near your personal information.

The Alien Number also appears on other official immigration documents, such as:

Employment Authorization Document (EAD)
USCIS notices and letters
Forms like the I-130 (Family Petition) or I-485 (Adjustment of Status)

It’s important to keep your Alien Number handy, as you will need it when dealing with USCIS or other government agencies.

Why is the Alien Number Important?

Your Alien Number on green card is not just a random number. It plays a significant role in many of your interactions with U.S. immigration authorities. Here’s why it matters:

Tracking Your Immigration History: The Alien Number helps track your immigration journey, whether you're applying for a Green Card, renewing your status, or becoming a U.S. citizen. It allows USCIS to keep your records in order.
Quick Reference: When you need to interact with USCIS or other government agencies, your Alien Number is like a shortcut. It helps officials pull up your records faster and more accurately, saving time.
Legal and Official Use: Your Alien Number is required on various forms and applications, whether you're seeking work authorization, applying for U.S. citizenship, or updating your Green Card. It’s a key part of your official immigration paperwork.
Proof of Legal Status: The Alien Number helps verify that you're a legal resident of the U.S. It’s used to confirm your legal status when applying for benefits or engaging in other legal matters.

How Does the Alien Number Relate to Other Documents?

Throughout your immigration process, your Alien Number will appear on multiple forms and documents. Here's how:

Green Card: Your Alien Number is tied to your Green Card, which is proof of your permanent residency.
Naturalization: When applying for U.S. citizenship, you’ll need to provide your Alien Number as part of the application process (Form N-400).
Renewing Your Green Card: If your Green Card expires, you’ll need to renew it using your Alien Number.

Whenever you're dealing with immigration paperwork, keep your Alien Number ready—it'll make everything easier.

Common Uses for Your Alien Number

You'll be using your Alien Number in several situations during your time in the U.S. Here are a few common scenarios:

Green Card Renewal: Green Cards are valid for 10 years. When it's time to renew your Green Card, you'll need your Alien Number to fill out the application.
Applying for Citizenship: If you’re ready to become a U.S. citizen, your Alien Number will be needed on your naturalization application.
Updating Immigration Records: If you need to change any personal information, such as your name or address, your Alien Number will be part of the update process.
Employment Authorization: If you’re applying for an Employment Authorization Document (EAD) or other work permits, you’ll use your Alien Number to help USCIS process your request.
Tracking Immigration Benefits: Your Alien Number helps USCIS track any benefits or applications you’re applying for, such as family-based petitions or adjustment of status.

How to Protect Your Alien Number

Your Alien Number is important, so you’ll want to keep it safe. Here are a few tips to protect it:

Store Documents Safely: Keep your Green Card and any other immigration-related documents in a safe place. Only carry them with you when necessary.
Be Careful with Sharing: While you’ll need to share your Alien Number when dealing with immigration paperwork, avoid giving it out casually or to untrusted sources.
Watch for Fraud: If you think someone might be using your Alien Number fraudulently, report it to USCIS right away.

Can You Change Your Alien Number?

Your Alien Number is permanent—it stays with you throughout your immigration journey. Even if you change your status (for example, from a Green Card holder to a U.S. citizen), your Alien Number remains in the system. However, you won’t need to use it once you’re a U.S. citizen, though it will still appear on your records for reference.

The Bottom Line

Understanding the Alien Number on your Green Card is key to navigating your immigration experience in the United States. This number plays a central role in helping USCIS and other government agencies track your case and process your applications.

From renewing your Green Card to applying for U.S. citizenship, your Alien Number is essential in almost every part of your immigration process. Be sure to keep it safe, use it when necessary, and always have it on hand when dealing with any immigration-related paperwork or government agencies.

If you need to update your status or resolve any issues, your Alien Number will ensure that your immigration records are processed quickly and correctly.

So, now that you know all about your Alien Number, keep it safe and use it wisely—it’s your key to navigating your immigration journey in the U.S.!
