U.S. immigration, understanding the nuances of identification numbers is crucial. Among the various identifiers, the Alien Registration Number (A-Number) stands out as a fundamental piece of documentation for immigrants and residents alike. This article aims to demystify the concept of A-numbers, where they can be found, their significance, and more.
What is an Alien Registration Number (A-Number)?
An Alien Registration Number, commonly referred to as an A-number, is a unique identifying number given to you by USCIS to non-citizens during their interactions with the U.S. immigration authorities. A-Numbers are assigned only to individuals who are not United States citizens. This number is issued by the U.S. Citizenship and Immigration Services (USCIS) and serves as a critical identifier throughout an individual's immigration journey. Your Alien Registration Number (A-Number) is unique to you. You will use this number when filling out all immigration forms throughout your lifetime. It helps track various aspects of immigration applications, statuses, and processes.
Are you eligible for A-Number?
Anyone who applies for a green card is eligible for an Alien Registration Number (A-Number). A-numbers are essential for all individuals who plan to live permanently in the United States. Eligibility for an A-Number is not dependent on the type of green card (family-based, refugee, employment-based, etc.). If you are moving to the United States permanently, you will receive an A-Number.
In addition to green card applicants, F-1 student visa holders are also assigned an A-Number, even though they are neither green card holders nor applicants.
Who is not eligible for an A-number?
Temporary non-immigrant visa recipients are not assigned A-numbers. Short-term stays in the United States do not require documentation that includes an A-number. The only exception to this rule is F-1 student visa holders.
Where to Find Your Alien Registration Number
Locating your A-Number depends on the specific immigration document you possess:
On a Green Card (Permanent Resident Card): The A-Number is prominently displayed on the front of the card under the heading "A-Number" or "USCIS#."
On an Employment Authorization Document (EAD): Similar to a Green Card, the A-Number can typically be found on the front of the card.
On Other Immigration Documents: Visa documents and other immigration-related paperwork issued by USCIS also feature the A-Number in a designated section.
Importance of the Alien Registration Number
The A-number plays a crucial role in various immigration processes:
Identification: It uniquely identifies individuals in the U.S. immigration system, ensuring accurate tracking of applications and statuses.
Application Processing: When filing for visas, green cards, or other benefits, including naturalization, the A-number is used to reference and process applications.
Legal Documentation: It serves as a key piece of information in legal proceedings and interactions with USCIS.

Alien Number Types
Understanding the different types of Alien Numbers can be crucial for navigating the U.S. immigration system effectively. Here's a breakdown of the various types of numbers you might encounter:
Alien Registration Number (A-Number):
This unique identifier is assigned to non-citizens by the U.S. Citizenship and Immigration Services (USCIS). It is used for tracking and managing immigration records and applications. The A-number is generally a nine-digit number and can be found on immigration documents such as Green Cards and Employment Authorization Documents (EADs).
USCIS Number:
Sometimes referred to as the "USCIS case number," this is a unique number assigned to each specific application or petition filed with USCIS. It differs from the A-Number in that it is tied to individual cases rather than the person themselves.
Receipt Number:
When you file an application or petition with USCIS, you will receive a receipt notice containing a receipt number. This number allows you to track the status of your case online. The format typically starts with three letters followed by ten numbers (e.g., EAC1234567890).
Social Security Number (SSN):
While not exclusively an "alien number," non-citizens who are authorized to work in the U.S. will be issued a Social Security Number, this number is used for tax and employment purposes and is a critical component of an individual’s financial identity in the U.S.
Visa Number:
The visa number, also known as the visa foil number, is a red number printed on the bottom right of a visa document. It is used to identify the visa issued to the individual.
Passport Number:
Again, while not an "alien number," the passport number is a critical identifier for any international travel and immigration processes. It is issued by the government of the individual’s home country.
Naturalization Certificate Number:
For individuals who have become U.S. citizens through naturalization, this number is found on the Certificate of Naturalization and serves as proof of citizenship.
Difference Between A-Number and USCIS Number
A common question we receive is, “Is a USCIS number the same as an alien number?” The answer is no; your Alien Registration Number (A-Number) is different from your USCIS case number. However, there is some confusion because the USCIS number on your green card is actually your A-Number, while your USCIS case number is different. It might be confusing since your A-Number is labeled as “USCIS#” on your green card, but we’re here to make it clear for you.
Here’s a breakdown to clarify:
Alien Registration Number (A-Number):
This is your identification number in the U.S. immigration system. It typically has 7, 8, or 9 digits. On your green card, the A-Number might be labeled as "USCIS #."
USCIS Case Number:
This number is assigned to each specific application or petition you file with USCIS.
It consists of three letters followed by ten numbers, totaling 13 characters (e.g., EAC1234567890).
Each application you submit to USCIS will have a unique USCIS case number. However, your A-number remains constant across all applications. The difference in the number of digits can help you distinguish between the two:
A-Number: 7, 8, or 9 digits
USCIS Case Number: 13 characters (3 letters + 10 numbers)
Understanding the distinction between these numbers is crucial for navigating the U.S. immigration process effectively.
Importance of Knowing Your Numbers
Understanding and correctly using these various numbers is essential for ensuring smooth interactions with the U.S. immigration system. Each number serves a specific purpose and helps in tracking your application status, verifying your identity, and maintaining accurate records. Always keep these numbers secure and readily accessible when dealing with immigration-related matters.
By familiarizing yourself with these different types of Alien Numbers, you can navigate the complex landscape of U.S. immigration more effectively and ensure that your applications and processes are handled efficiently.
Example of an Alien Registration Number
Most of the A-numbers consist of nine digits, they have a specific format such as "A000 000 000." This format varies slightly across different immigration documents but generally adheres to a consistent structure. However, some A-numbers are shorter. If your A-number has fewer than nine digits, you should add zeros between the “A” and the first digit to make it a complete nine-digit number. For example, if your A-Number is 1234567, it should be written as A001234567.
What Happens If You Lose Your Alien Number?
If you lose your physical green card or any other immigration documents containing your A-Number, you can still retrieve your A-Number. You can access it through the Freedom of Information Act (FOIA) online system or by setting up an appointment with USCIS. If you need help with this process or have any questions, you can find out on U.S. Citizenship and Immigration Offices.
Understanding your Alien Registration Number (A-Number) is essential for navigating the complexities of U.S. immigration. It serves as a critical identifier throughout your interactions with USCIS, ensuring accurate processing of applications and legal documentation. By knowing where to find your A-Number, its significance, and how it differs from other identification numbers, you empower yourself to navigate immigration processes effectively.

Common Mistakes or Issues Related to A-Number
Common Mistakes with A-Numbers often stem from misunderstandings or bureaucrat errors during immigration processes. One prevalent issue is confusion between the A-Number and the USCIS Case Number, especially since the A-Number is sometimes labeled as "USCIS #" on documents like green cards. This confusion can lead to errors in filling out forms or tracking application statuses. As I mentioned earlier, it might be confusing but I made it clear to you at the beginning of this article.
Another common mistake involves errors in the format of the A-Number itself, such as missing or incorrectly placed digits. Misplacement or loss of A-Number documentation can also pose significant challenges, as this number is crucial for verifying identity and processing immigration applications.
Furthermore, difficulties may arise when updating A-Number information due to changes in immigration status or personal details. It's essential to keep A-Numbers secure and up-to-date to avoid delays or complications in immigration proceedings. Addressing these issues requires careful attention to detail and adherence to USCIS guidelines to ensure accurate processing and documentation throughout the immigration journey.
USCIS will use your A-Number to identify your immigration records, and you will use this number for every documentation related to citizenship and/or immigration.
