An immigration alien number search serves as the primary method for individuals to verify status and track an application within the United States immigration system. Every non-citizen interacting with U.S. Citizenship and Immigration Services receives a unique identifier, commonly known as the A-number, which functions as a permanent reference throughout the immigration process. This numerical code allows applicants, attorneys, and family members to locate specific records efficiently and ensures that all documentation corresponds to the correct person.
Understanding the Alien Number and Its Importance
The alien number, or A-number, is a seven- or eight-digit code assigned by the Department of Homeland Security to identify a foreign national in all immigration records. This identifier appears on nearly every official document, including work permits, green cards, and admission stamps, making it indispensable for verifying identity. Conducting an immigration alien number search helps eliminate confusion caused by similar names or dates of birth, providing precise results for the intended individual.
Common Reasons to Search for an A-Number
Individuals often initiate an immigration alien number search to monitor the progress of a pending application or to confirm the status of a family member’s case. Employers may require the number to validate employment authorization, while legal representatives rely on it to access court filings and immigration dockets. Additionally, beneficiaries seeking to adjust status or extend their stay depend on this search to ensure their documentation remains current and valid.
Where to Locate an Alien Number
Your alien number is typically printed on the front of your Employment Authorization Document (EAD) or Green Card, making it easily visible without specialized tools. For those without these physical documents, the number may appear on prior notices of action issued by USCIS or on the visa stamp inside a passport. When these records are unavailable, an authorized representative can often retrieve the A-number through secure government databases.

How to Perform an Online Immigration Alien Number Search
To conduct an immigration alien number search, you generally need the exact number and a valid email address linked to the case. Start by visiting the official USCIS website and navigating to the case status portal, where entering the A-number and receipt number can reveal current processing information. Keep in mind that some sensitive case details may require additional verification or access through an authorized attorney.
Interpreting Search Results and Case Status
After submitting the alien number, the portal will display key details such as the case type, current adjudication stage, and expected processing timeframe. If the status shows "Received" or "Under Review," it indicates that immigration officers are actively handling the application. Should the results return an error or outdated information, double-check the digits or contact the USCIS contact center for immediate assistance.
Privacy and Security Considerations
Protecting the confidentiality of an alien number is critical, as it provides access to sensitive personal and legal information. Always perform an immigration alien number search on official government domains to avoid phishing sites that could compromise data. When sharing the number with third parties, confirm their credentials and request formal documentation to justify the need for access to immigration records.
