Locating your Alien Registration Number (ARN) is often the first critical step in managing any immigration matter in the United States. This unique identifier, issued by U.S. Citizenship and Immigration Services (USCIS), serves as the primary key linking you to your immigration records. Whether you are applying for a work permit, adjusting status, or simply verifying your case history, knowing where to find this number is essential for efficiency and accuracy.
Understanding the Alien Registration Number
The Alien Registration Number is a unique identification code assigned to every non-citizen required to register with the U.S. government. It is a lifelong identifier that travels with the individual, regardless of changes in immigration status. You will recognize it immediately as it typically appears as a letter followed by seven or eight digits (for example, A12345678) or starts with the letter "C" followed by seven digits for certain specific cases. This number is fundamentally different from a Green Card number, although it may appear on the same physical document.
Primary Location on Physical Documents
For the majority of applicants and office visitors, the most reliable place to locate the ARN is on the physical immigration documents issued by USCIS. If you are looking at a physical Form I-94, the number is printed clearly at the top of the document. On older paper Forms I-551, commonly known as the Green Card, you will find the ARN in the top right-hand corner of the front side. It is usually situated directly below the heading "Registration Number" or "Reg. No."
Digital Records and Online Accounts
In the digital age, your ARN is readily accessible through your USCIS online account. By logging into the official USCIS website and navigating to your account dashboard, you can view the ARN associated with any current or pending case. Furthermore, if you have submitted forms or requested records electronically, the ARN will be included in the subject line of the confirmation emails you receive from USCIS. Always double-check these digital communications to ensure you have recorded the correct sequence of letters and numbers.
Locating the Number on I-94 and I-797 Forms
Specific forms have designated fields for this identifier. On the electronic I-94, which is now primarily issued in digital format, the ARN is listed under the "Admitter's Number" section if the traveler is in a non-immigrant status. For employment-based applications, the Form I-797 Notice of Action will prominently feature the ARN in the header section. This number ensures that the case details are matched precisely to the correct individual during the adjudication process.
Common Issues and Verification Tips
Misplacing or misreading this identifier is a common issue that leads to delays in processing. When verifying the number, it is vital to distinguish between the ARN and the case number. The case number is typically a receipt number that ends with "USCIS" and is used to track the specific petition. The ARN, however, belongs to the person. If you are unable to locate the number on your documents, contacting USCIS customer service or checking your case status online through the USCIS website will reveal the correct registration identifier associated with your file.
