Where You Can Find Your Alien Number

The alien number, also known as an A-number or A-Number, is a unique eleven-digit identifier used by U.S. Citizenship and Immigration Services (USCIS) and other U.S. government agencies to track an immigrant’s case. This number is essential for immigration applications, checking case status, and communicating with USCIS. It appears on several official documents and records, and knowing where to locate it can save time during the application process. This guide explains where to find your alien number, what it looks like, and how to use it across different situations.

What Is an Alien Number (A-Number) and When Is It Used

An A-number is a unique eleven-digit code assigned to noncitizens by the U.S. government. It stays with the individual throughout their immigration journey, even if their status changes. The A-number helps USCIS and other agencies consolidate records, avoid duplicate files, and securely fetch your information in internal systems. Common scenarios that require the A-number include adjusting status, applying for a work permit, requesting asylum, appealing a decision, and renewing or replacing travel documents. Keeping this number handy improves accuracy and reduces processing delays.

Where to Find Your Alien Number on Official Documents

Several immigration documents display the A-number in visible and clearly labeled forms. Look for the term “A-Number” or the lettered string “A” followed by eleven digits. Here are the most common locations:

  • Employment Authorization Document (EAD, Form I-688B or I-766): The A-number is listed on the card, often near the card’s bottom or along the edges.
  • Arrival-Departure Record (Form I-94): In some versions, the A-number appears on the I-94 record or I-94 arrival/departure card, especially for individuals with immigration status changes.
  • Other USCIS Notices: Various letters, requests for evidence (RFEs), and status updates may display the A-number in the header or body of the document.
  • USCIS Online Account: If you create a USCIS online account, you can view your A-number under your profile and case details.

Finding Your Alien Number in the USCIS Online Account

Creating and accessing a USCIS online account streamlines many tasks. After logging in, navigate to the “My Profile” or “Case Status” section to locate your A-number. If you have a pending application, the A-number is tied to your case number and will be displayed in the case details. For family-based petitions or dependent cases, each individual may have a separate A-number, so verify the label next to the number to avoid confusion.

What If You Can’t Find Your A-Number on Documents?

If your documents do not clearly show an A-number, or if the number is missing, consider these steps:

  • Check all current USCIS notices: Review all active notices, approval letters, and requests for evidence attached to your case.
  • Consult your immigration attorney or accredited representative: They can locate the number in your file or retrieve it from USCIS systems.
  • Contact USCIS: Use the USCIS contact center or schedule an appointment through Infopass to verify your records. Have identifying information ready, such as full name, date of birth, country of origin, and any case receipt numbers.
  • Check trusted portals or government databases: In some scenarios, other government portals may reference your A-number when linking multiple records.

Use Cases: How the A-Number Helps in Immigration Processes

The A-number is used across a range of immigration actions. Understanding where to find it and how to use it can prevent delays. Key use cases include:

  • Adjusting Status: When filing Form I-485, the A-number identifies your case across USCIS systems and helps link documents to your profile.
  • Applying for Work Authorization and Travel Documents: The A-number ensures your employment and travel documents are associated with the correct individual.
  • Naturalization and Green Card Renewals: When renewing or updating immigration status, the A-number remains the consistent identifier in all records.
  • Appeals and Motions: In appeals or motions, the A-number helps clerks locate the precise case file within the agency’s databases.

Tips for Keeping Your A-Number Safe

Because the A-number is a sensitive personal identifier, it should be protected to prevent identity theft and fraud. Consider these precautions:

  • Store securely: Keep physical copies in a safe place and protect digital copies with strong passwords and encryption.
  • Share only when necessary: Provide your A-number only to trusted officials or institutions involved in your immigration process.
  • Verify requests: If you receive a request for your A-number from an unfamiliar source, verify its legitimacy before sharing information.
  • Monitor communications: Be alert for suspicious messages or requests that claim to need your A-number and contact USCIS directly to verify.

Frequently Asked Questions

Q: Is the A-number the same as a Social Security Number (SSN)? A: No. The A-number is an immigration identifier issued by USCIS, while the SSN is a separate Social Security identifier used for employment, taxes, and social benefits. Do not confuse the two, and share each only as required for the respective process.

Q: Can I have more than one A-number? A: Generally, a person retains a single A-number throughout their immigration journey. If a duplicate appears due to a clerical error, contact USCIS to correct it.
