USCIS Online Account Number: Where to Find It

The Short Answer

Your USCIS online account number (OAN) is a unique identifier assigned when you create an account at my.uscis.gov. It is usually 10 to 12 digits long and is completely different from your A-number (alien registration number). The online account number links your paper filings and your online case tracking to the same USCIS online account, so you can receive notifications, upload documents, and check case status digitally.

If you have never created a my.uscis.gov account, you do not have an online account number. That is perfectly normal for anyone who has only filed paper applications. Many USCIS forms that ask for the online account number accept a blank response in this situation.

Where to Find Your Online Account Number

There are three common places where the online account number appears:

1. Inside Your my.uscis.gov Account

This is the primary source. Go to my.uscis.gov and log in with the email address and password you used to create the account. Once you are logged in, your online account number is displayed on your dashboard or in your account profile, usually labeled "USCIS Online Account Number" or "OAN." It is typically a 10- to 12-digit number.

If you forgot your my.uscis.gov login, use the password reset option to regain access. If you forgot which email address you used, try any email addresses you may have used around the time you first filed online with USCIS.

2. On Recent Form I-797C Receipt Notices

If you filed an application through your my.uscis.gov account (or linked a paper filing to the account), the I-797C receipt notice often includes the online account number in the header or in a dedicated field labeled "USCIS Online Account Number." This is the most common place where people first see the number printed outside the account dashboard.

The receipt notice also displays the receipt number (beginning with three letters such as MSC, EAC, LIN, or SRC followed by ten digits). The receipt number and the online account number are different — do not confuse them.

3. On the USCIS Access Notice

When you first create a my.uscis.gov account, USCIS sends a confirmation email and, in some cases, a letter or notice that contains your online account number. Check your email archive for correspondence from USCIS around the time you first accessed the portal.

What the Online Account Number Is Used For

The online account number serves as a link between your physical filings and your digital tracking. Specifically, it is used to:

• Link paper applications to your online account. When you file a form by mail, you can include your online account number so that the case automatically appears in your my.uscis.gov dashboard.
• Receive electronic notifications. USCIS uses the online account to send email updates when your case status changes, rather than relying solely on paper mail.
• Upload documents. Some USCIS processes allow document uploads directly into the online account for existing cases.
• Track multiple cases in one place. If you have several filings in progress, the online account shows them all in a single dashboard.
• Respond to RFEs digitally. Some RFE responses can now be submitted through the online account.

How the Online Account Number Is Different from Your A-Number

These two numbers are frequently confused. They serve very different purposes:

• A-number (or USCIS number on a green card): A permanent nine-digit identifier that follows you through USCIS records from the first moment you have a USCIS file until forever. It identifies you as a person in USCIS databases.
• USCIS online account number: A digital identifier created when you open a my.uscis.gov account. It identifies your online account, not you. It is not permanent in the same way — if you never create an online account, you do not have one.

When a USCIS form asks for your "A-number" or "alien registration number" or "USCIS number," it is asking for the nine-digit A-number. When it asks for "USCIS online account number" or "USCIS OAN," it is asking for the digital account identifier. Reading the field label carefully is essential — entering the wrong number in the wrong field is a common reason for rejected filings.

What If You Do Not Have an Online Account Number?

If you have never filed online with USCIS and never created a my.uscis.gov account, you do not have an online account number. That is perfectly normal. When a form asks for it, you can either leave the field blank (most forms allow this) or enter "N/A."

If you want to create an online account now — for example, to track a current case digitally or file future applications online — go to my.uscis.gov/account/v1/needToSignUp and follow the registration process. You will receive an online account number as part of the sign-up.

What If You Cannot Access Your Account?

If you have an online account but cannot log in, the most common fixes are:

1. Password reset. Use the "Forgot Password" link on the login page.
2. Email recovery. Use the "Forgot Username" link to find which email address is associated with the account.
3. Identity verification. If you cannot recover access through email, USCIS has a process for verifying your identity and recovering the account. This may require you to answer security questions and provide personal details that match your USCIS records.
4. Call the USCIS Contact Center for additional help if the online recovery does not work.

Security Considerations

Your online account contains sensitive personal information and case details. Protect it the same way you would protect a bank login:

• Use a strong, unique password.
• Enable two-factor authentication if available.
• Never share your login credentials with anyone, including immigration consultants who may ask for them. A licensed attorney typically works with their own G-28 representation rather than logging into your account.
• Watch for phishing emails pretending to be from USCIS. Real USCIS emails come from uscis.dhs.gov domains and do not ask you to log in through a link in the email.

The Bottom Line

Your USCIS online account number is separate from your A-number. You can find it inside your my.uscis.gov account, on recent I-797C receipt notices linked to the account, or in USCIS email confirmations from when you first registered. If you have never created an online account, you do not have an online account number and can leave that field blank on most forms. Read each form field carefully to avoid entering the wrong identifier.

When to Work with an Immigration Attorney

Not every immigration question needs a lawyer, but some do. The topics covered in this article include situations where a brief consultation with a licensed U.S. immigration attorney can save months of delay, prevent irreversible mistakes, and identify options you might not otherwise know about. Consider consulting an attorney if your case involves any of the following:

• Criminal history of any kind. Even dismissed charges, expunged records, or decades-old offenses can affect immigration outcomes. The immigration consequences of a criminal record are technical and fact-specific, and plea deals that seemed favorable in criminal court sometimes have devastating immigration consequences.
• Past immigration violations or denials. Prior visa denials, overstays, periods of unlawful presence, and prior removal proceedings all affect current options. An attorney can review your history and identify which paths remain open.
• Complicated family situations. Divorce, death of a petitioner, domestic abuse, and similar circumstances can trigger waiver eligibility or affect existing petitions in ways that require careful legal analysis.
• Business immigration matters. Employment-based cases, investor visas, and self-petitions are typically too complex for do-it-yourself filing. The evidentiary standards are demanding and the stakes are high.
• Cases that feel stuck. If your case has been sitting without action for a long time, or if you received an RFE or NOID you do not fully understand, an attorney can diagnose the problem and respond effectively.
• Anything you do not fully understand. Immigration forms are technical, and a small mistake can cascade into large consequences. When in doubt, ask someone qualified.

Finding Reliable Information

The single most reliable source of current U.S. immigration information is USCIS itself. USCIS publishes form instructions, fee schedules, processing times, policy manuals, and policy alerts at uscis.gov. When any article (including this one) references specific fees, processing times, or eligibility rules, the information can become outdated as USCIS updates its policies and fee schedules. Always verify any time-sensitive detail directly with USCIS before filing anything.

Other reliable primary sources include the U.S. Department of State (for visa bulletins and consular processing), the U.S. Department of Labor (for PERM and prevailing wage information), U.S. Customs and Border Protection (for admission and port of entry rules), and the Executive Office for Immigration Review (for immigration court procedures).

Secondary sources — including practitioner guides, law school immigration clinics, and reputable nonprofit legal aid organizations — can provide helpful explanations of how the rules apply in practice. Community forums and social media should be treated with caution: they can point you to useful resources, but they also contain a great deal of inaccurate or outdated information, and the rules change frequently enough that what was true a year ago may not be true now.

Keeping Records

One of the simplest ways to protect yourself through any immigration process is to keep careful records of everything. Copies of every filing you send to USCIS, every notice you receive, every check or money order you submit, and every piece of correspondence you send or receive become critical evidence if something goes wrong later. Keep these records organized, dated, and backed up in at least two separate places (for example, a physical folder and a digital scan).

Also keep records of everything that supports your underlying eligibility — tax returns, marriage certificate, birth certificates, medical records, employment records, property records, school transcripts, and anything else that demonstrates ties to the United States, family relationships, or program eligibility. Good records are the backbone of a strong immigration case.
