Locating an Alien Registration Number is often the first critical step for immigrants, legal representatives, and researchers dealing with United States immigration records. This unique identifier, also known as the A-Number, serves as the primary key in the Department of Homeland Security's databases, linking an individual to their entire immigration history. Finding this number is essential for completing forms, tracking case status, or verifying identity for official purposes.
Understanding the Alien Registration Number
The Alien Registration Number is a unique identifier assigned to every non-citizen required to register with the United States government. Originally created for the Alien Registration Act, this number remains the central reference point for immigration records. It is distinct from other identification numbers, such as a Social Security Number, and is typically the first piece of information needed when interacting with U.S. Citizenship and Immigration Services (USCIS).
Physical Appearance and Format
An A-Number is usually formatted as a letter followed by eight digits (for example, A12345678) or as a letter followed by seven digits (for example, A1234567). The letter at the beginning often indicates the type of immigration benefit or the era in which the registration was processed. When searching for this number, it is crucial to distinguish it from other codes, as even one digit can lead to an entirely different file.
Where to Find the Number on Physical Documents
If you are holding original immigration documents, the registration number is prominently displayed in specific locations. Checking these areas first can save significant time compared to digital searches. Always handle physical documents with care to avoid tearing or smudging the ink.
Form I-551, the Permanent Resident Card: The A-Number is listed on the front of the card, usually in the top right corner or center section, above the card number.
Form I-94, the Arrival/Departure Record: For those admitted at a port of entry, the number is found on the upper right corner of the paper I-94 or within the electronic record data.
Old Registration Receipts: Any correspondence from the Immigration and Naturalization Service (INS) historically included this number on the top left of the document.
Searching Digital USCIS Records
For individuals who do not have physical documents or whose records are outdated, the USCIS provides digital avenues for retrieval. However, accessing these records often requires verifying identity to protect privacy. Prepare specific details about your case, such as your date of birth and country of origin, to streamline the process.
Using the USCIS Case Status Online Tool
The most common method is to check your case status through the official USCIS website. By entering your biographical information, the portal will display your case details, where the Alien Registration Number is usually visible in the URL or the main body of the case history. This number can then be copied for use in subsequent applications or inquiries.
When Documents Are Lost or Unavailable
In scenarios where an immigrant has lost their Green Card or never received physical documentation, alternative methods exist to retrieve the registration number. Contacting the agency responsible for the original filing or the office that processed the application is the next logical step. Be prepared to provide secondary evidence of identity, such as birth certificates or old tax records, to verify your identity before they release sensitive data.
Leveraging the FOIA Process
If standard channels do not yield results, filing a Freedom of Information Act (FOIA) request is a formal option to access government files. This process allows individuals to request their immigration records directly from the National Archives. While this method requires patience, it is a reliable way to obtain a verified copy of the Alien Registration Number when all other options are exhausted.
