A USCIS online account number is a unique 12-digit numeric identifier tied to your myUSCIS online profile. It is different from case number, receipt number, and Alien Registration Number. USCIS assigns it so that every filing, notice, and case update connected to you links back to one digital account.
Key Takeaways
- A USCIS online account number is a 12-digit number that identifies you as a user in the USCIS digital system, and it stays the same no matter how many applications you file.
- You can find it in the profile section of your myUSCIS account, and it also appears on some USCIS notices, including an Online Account Access Notice and certain I-797C receipt notices.
- USCIS issues the number after online applications or specific receipt numbers are assigned, so creating a profile on the myUSCIS portal does not automatically generate one in every situation.
- Forms that ask for the number label the field "if any," and providing it helps USCIS tie your filing to your existing profile so the case shows up in your dashboard.
- Ellis keeps the important numbers for every employee in one place, so the right identifier lands on every filing. See how it works →
What Is a USCIS Online Account Number?
A USCIS online account number works like a customer ID for the USCIS online system. It is a 12-digit number (like 123456789012) that USCIS assigns to one person's myUSCIS profile, and it stays the same regardless of how many applications or petitions that person files over time.
The system generates the number when someone creates a myUSCIS online account, or when USCIS creates an account on their behalf. Once assigned, the number allows applicants to link and organize multiple filings under one profile, so every benefit request, notice, and case update sits under a single digital identity.
The number grants no immigration status by itself. It is an administrative tool that helps USCIS connect your data across filings and digital interactions.
The label changes depending on where you see it:
- USCIS online account number, the standard label on current forms.
- Online account number, or USCIS account number, on various notices.
- OAN, the shorthand USCIS uses in some instructions.
- USCIS Online Account (ELIS) Number, on older forms, named after the retired Electronic Immigration System.
Forms asking for it mark the field "if any," since not everyone makes an account.
Where Do You Find Your USCIS Online Account Number?
If you filed online, the fastest route is your myUSCIS dashboard. If you filed by mail and received an IOE-prefix receipt, the number may be on a paper notice USCIS already sent you.
In your myUSCIS online account
1. Log in at my.uscis.gov with your email and password.
2. Open your profile or account settings area. The link is usually labeled "Profile" or "Account Profile" in the header or menu.
3. Find the label "USCIS Online Account Number" or "Account Number" and read the 12-digit value displayed there.
This is the most reliable, up-to-date place to confirm your number. Users can access their USCIS online account anytime, and USCIS case status updates are available 24/7 online, so there is no need to wait for business hours to look it up. The layout of the USCIS website changes over time, so the exact location of the profile section may shift, but the number will sit somewhere in your account settings.
On USCIS notices and correspondence
Some I-797C receipt notices and other USCIS letters print the USCIS online account number in a dedicated field, often near the top of the first page. It shows up most often on:
- Receipt notices for online-filed forms such as Form I-90, N-400, I-130, I-539, I-765, or I-129F, especially for filings submitted after USCIS enabled online filing for those form types.
- An Online Account Access Notice, which USCIS sends when it creates or links an online account for you and wants to provide instructions for accessing it.
Each identifier printed on the same page looks different. The receipt number carries a three-letter prefix such as IOE, WAC, LIN, SRC, or EAC followed by 10 digits. The Alien Registration Number, or A-Number, starts with "A" followed by 8 or 9 digits. The USCIS online account number is purely numeric and 12 digits long, with no letter prefix. Older paper-only filings may show no online account number field at all.
If USCIS created an account for you
USCIS sometimes creates an online account automatically when someone files certain forms online, or when an attorney files on their behalf. In those cases, USCIS may send a paper notice or email containing:
- A USCIS online account number.
- Instructions for accessing or linking that government-created account by setting up login credentials at my.uscis.gov.
Initial receipt notices and any letters titled "USCIS Account Access" or "USCIS Online Account" are the first place to look. Account creation notifications also arrive by email, so an inbox search for messages from USCIS often turns one up.
How Is It Different From Other Immigration Numbers?
Immigration documents carry several different numbers, and they are easy to confuse. The USCIS online account number identifies your online profile, while other numbers identify specific cases, individuals, or visa categories.
Identifier | Format | What it identifies |
|---|---|---|
USCIS online account number | 12 digits, no letters | Your myUSCIS profile. Stays the same across all filings. |
USCIS receipt number | 13 characters, such as IOE1234567890 | One specific case. Each application gets its own. |
Alien Registration Number | "A" plus 8 or 9 digits | A noncitizen across their entire immigration history. |
NVC case number or DOS case ID | Varies | A consular processing case at the National Visa Center or Department of State. |
Online access code | Temporary code mailed by USCIS | A one-time key for linking a paper-filed case to your online account. |
On green cards issued after May 2010, USCIS uses the label "USCIS Number" on the card, but it refers to the same A-Number. That label trips people up, and so does the visa number printed on a visa foil, which serves a different purpose again.
Entering the wrong type of number on a USCIS form can lead to a Request for Evidence or processing delays. Because the online account number is purely numeric with no letter prefix, a quick format check catches most mix-ups before a form goes out the door.
Why Does Your USCIS Online Account Number Matter?
A linked account changes how USCIS reaches you:
- Everything lands in one place. USCIS allows online case tracking for immigration applications, so case status updates, biometrics appointment notices, and requests for evidence arrive there instead of in the mail, with digital notifications when something changes.
- You answer without mailing anything. USCIS allows secure messaging and evidence uploading through accounts linked with an online account number, so you send additional documents from the dashboard.
- Your details carry over. The account reuses data you already entered, including travel history.
For employers, one number keeps filings attached to the right employee across multiple petitions, cuts duplicate accounts, and gives HR and immigration counsel a single identifier to quote. The USCIS online account number helps manage immigration paperwork efficiently.
How Do You Get a USCIS Online Account Number?
There is no separate application. USCIS assigns the number once you have an account with a filing attached to it, so creating a profile on the myUSCIS portal does not automatically generate a USCIS online account number in every situation.
That makes it two steps:
- Create a myUSCIS account. USCIS covers the steps on its how to create a USCIS online account page. A personal email you keep avoids recovery trouble later.
- File online, or link an existing paper case to that account. Linking takes your Form I-797C receipt number, matching personal details, and sometimes an online access code. Not all forms are accepted, and the current list is on uscis.gov. Once linked, notices and some RFEs arrive online too.
USCIS may have done both for you already. Any notice carrying an IOE-prefix receipt number means the number exists, and so does an account created for an earlier benefit request such as an N-400 for citizenship. "Forgot password" at my.uscis.gov recovers a lost login, and the USCIS Contact Center handles the rest.
Employers use a USCIS organizational account instead.
How Do HR Teams Use USCIS Online Accounts?
For People teams at companies that sponsor work visas and green cards, the number links the employee's USCIS profile, your HR records alongside Form I-9 compliance, and your counsel's case management.
Employees move offices, change roles, and swap email addresses. The number on file keeps their USCIS notices arriving. USCIS, part of the Department of Homeland Security (DHS), keeps moving toward mandatory e-filing.
Most teams set policy on four points:
- Ownership. Employees own their own accounts, on a personal email address. A number belongs to one person and never transfers between employees.
- Sharing. Employees pass the number to the in-house mobility team.
- Storage. Secure systems hold the number, never login passwords.
- Scope. Larger teams also run a USCIS organizational account for H-1B registrations.
