The Alien Registration Number (A-number) is a unique identifier assigned by U.S. Citizenship and Immigration Services (USCIS) to noncitizens. For H4 dependents, locating this number can be essential for immigration records, work authorization processes, and case status checks. This article explains where to find the A-number, what forms and documents typically display it, and how to retrieve it if the number is missing or misplaced.
Common Places Where The A-Number Appears
Several official documents consistently display the A-number. For H4 holders, these sources are the most reliable starting points. The A-number is formatted with the letter “A” followed by eight or nine digits (e.g., A012345678).
- I-94 Arrival-Departure Record: The A-number is often listed on the admission stamp or the paper I-94, as well as the electronic version accessed after entry. Look for “A-Number” or the numeral string beginning with “A.”
- USCIS Approval Notices (e.g., Form I-797): When an immigration petition or status adjustment is approved, the A-number is frequently included on the I-797 approval notice under “Alien Registration Number.”
- Employment Authorization Documents (EAD Card) — if applicable: Some H4 holders who obtain an EAD to work will have the A-number printed on the card or listed in the associated documentation.
- Notice of Action and Other USCIS Correspondence: Subsequent letters, approvals, or requests for evidence from USCIS may display the A-number for tracking purposes.
- Online USCIS Account or Case Status Page: If a case is linked to an online account, the A-number may appear in the case details or profile information.
How To Find The A-Number On Important Documents
Each document has a typical location to check for the A-number. Here are practical search tips for common forms and notices.
- I-94: Open the electronic I-94 record and inspect the header or the statute sections where identifiers are listed. On a paper I-94, the A-number is often near the top as “Alien Registration Number.”
- I-797 Approval Notice: Scan the document for a line labeled “Alien Registration Number” or a boxed section containing “A-number.” If the notice is a renewal or extension, the A-number may repeat in multiple pages.
- The A-number can appear on the front or back of the card, often near the top or the “A-Number” label. Ensure you copy the exact digits, preserving the leading “A.”
- Letters from USCIS frequently place the A-number under the recipient’s name and address block or within the “Beneficiary/Applicant Information” section.
- If the user has a My USCIS account, log in and navigate to the case details or profile. The A-number is typically listed in the personal information area or in the case summary.
Alternative Ways To Retrieve The A-Number
If the A-number is not readily visible on documents, several legitimate methods exist to retrieve it without compromising security.
- Enter identifying information and reference numbers to pull up case details. The A-number, if associated with the case, may appear in the result set.
- Submit a FOIA request to obtain records, including A-numbers, associated with the individual. This process can take time but provides a comprehensive record set.
- Contact USCIS for guidance on locating the A-number. Be prepared to verify identity and provide case identifiers to confirm ownership of the records.
- Some employers or educational institutions may have started processes that include the A-number as part of the immigration documentation, especially for work authorization tracking. Access is restricted and should be pursued through proper channels.
Important Clarifications For H4 Holders
Understanding what the A-number represents helps prevent confusion with other identifiers like a Social Security Number (SSN).
- The A-number is a federal immigration identifier, not a tax or employment identification number. The SSN is used for payroll and benefits but is separate from the A-number.
- The A-number is generally not printed on a driver’s license, passport, or foreign visa stamp. Those documents may display other identifiers, such as passport numbers or visa type, but not the A-number.
- Treat the A-number as sensitive personal information. Share it only with trusted entities and through secure channels.
Tips For Keeping Your A-Number Organized
Proactive organization helps prevent future retrieval challenges. Consider these best practices.
- Save a password-protected scanned PDF of the I-94, I-797, and any EAD notices where the A-number is present. Use a descriptive file name.
- Store originals in a labeled folder with a list of documents that contain the A-number for quick reference.
- If USCIS online accounts are used, ensure the A-number is visible and linked to the correct profile to avoid mismatches.
- Periodically check for updated notices, especially after petitions, renewals, or changes in status, to capture any new A-number references.
Common Scenarios And How The A-Number Is Used
Knowing typical scenarios helps illustrate why the A-number matters for H4 holders.
- When filing forms like I-539 (change or extension of nonimmigrant status), the A-number is used to track the dependent’s record alongside the primary applicant.
- If an H4 holder applies for an EAD, the A-number links the EAD to the applicant’s immigration file for efficient processing.
- Reentry or travel records sometimes reference the A-number to ensure the correct individual is identified in immigration systems.
In summary, the A-number for H4 holders is most reliably found on the I-94, I-797, and EAD documents, as well as in USCIS online accounts and official correspondence. When those sources are not accessible, USCIS customer service or a FOIA request can provide a pathway to retrieve the number securely.
