An alien registration number on an Employment Authorization Document, often abbreviated as EAD, serves as a critical identifier for non-citizens authorized to work in the United States. This unique, seven or ten-digit number is assigned by U.S. Citizenship and Immigration Services (USCIS) and acts as a lifeline, linking an individual’s employment eligibility to their immigration case. Without this number, proving the right to work or accessing government benefits becomes an immediate and significant hurdle.
Understanding the Basics of EAD and A-Number
The Employment Authorization Document is a card issued to individuals who are not permanent residents but are legally permitted to work. The alien registration number is the primary piece of information on this card, printed prominently for verification purposes. It is essential to distinguish this number from other identifiers, such as a Green Card number, which applies to lawful permanent residents. While both are forms of identification, the A-number on an EAD specifically tracks non-immigrant or temporary immigrant status related to employment authorization.
Locating Your A-Number on the Card
Finding the alien registration number on your EAD is usually straightforward, but it requires knowing where to look. The number is typically located in the upper right-hand corner of the front side of the card. It is often labeled as "A#" or "USCIS #" followed by a series of numbers. If you are looking at the back of the card, you will usually find a different number, such as the document number or a confirmation number, which should not be confused with the registration number.
Check the front of the card, top right section.
Look for the label "A Number" or "USCIS Number".
Ensure the number corresponds to the "Receipt Number" field if you are cross-referencing application records.
Why This Number Is More Than Just Digits
Beyond being a simple identifier, the alien registration number on an EAD is a key to accessing the broader U.S. immigration system. Employers use this number to verify employment eligibility through the federal E-Verify system, ensuring compliance with hiring regulations. Government agencies, financial institutions, and legal representatives also rely on this number to pull up an individual’s specific immigration case file. It is the thread that connects an applicant to their entire immigration history, including pending applications or granted statuses.
Common Issues and Misconceptions
Confusion frequently arises between the alien registration number and other codes found on immigration documents. For instance, the "USCIS Number" printed on an EAD is indeed the A-number for applicants who are adjusting status inside the U.S. However, for those applying abroad, the "USCIS Number" might refer to the office that handled the case, which is different. Furthermore, individuals who change immigration status might worry that their A-number changes; generally, this number remains the same throughout the duration of their immigration journey, providing continuity.
Do not confuse the A-number with the document number located on the bottom of the card.
Beware of scams requesting this number via unsolicited emails or calls; treat it like sensitive personal data.
Remember that while the physical card can be lost, the number associated with your case remains constant.
What to Do If You Cannot Find the Number
Losing the physical EAD card is a common scenario, and it can be stressful when you need the alien registration number for a background check or application form. If this happens, you should immediately check your immigration case files. The A-number is usually listed on any correspondence from USCIS, including receipts for filing fees and approval notices. You can also access this information through the USCIS online account portal if you have a profile, or by contacting the USCIS contact center directly for verification assistance.
