If you’re preparing a USCIS form, you may come across a question asking for a USCIS online account number. For many applicants, this is the first time they’ve seen the term. You may wonder whether it’s something you were supposed to receive, where to find it, or whether leaving it blank could delay your case.
This guide explains how USCIS online accounts work, what the USCIS online account number actually represents, and when USCIS expects you to provide it. We’ll also clear up common misunderstandings, including why many applicants never receive this number and what USCIS instructs you to do when a form asks for it anyway.
What Is a USCIS Online Account?
A USCIS online account is a secure profile on the U.S. Citizenship and Immigration Services website. USCIS calls it a myUSCIS account.
They explain that online accounts let applicants file forms, track cases, and receive messages electronically. Additionally, you can upload evidence and respond to USCIS requests through the account.
Key things you can do with a USCIS online account:
- File certain immigration forms online
- Track case status updates
- Receive USCIS notices electronically
- Send secure messages to USCIS
- Upload supporting documents
What Is a USCIS Online Account Number?
The USCIS online account number (OAN) is a unique identifier assigned to some applicants. Generally, the number is 12 digits in length. USCIS says they use it to connect your online account with your immigration filings.
This number is not the same as:
- Your A-Number (Alien Registration Number)
- Your receipt number (e.g., IOE, LIN, SRC)
- Your Social Security number
USCIS confirms that many applicants do not have an online account number. If you never created an online account or filed online, you likely won’t have one.
What's more, USCIS online account numbers are not just assigned to immigrants. Petitioners, who may be natural-born citizens could have an account. Likewise, attorneys also have an account to manage clients’ cases online.
When USCIS Issues an Online Account Number
Creating the USCIS online account does not automatically create a USCIS Online Account Number. You only have the OAN if you previously filed an case that uses an IOE receipt number. Therefore, do not assume you have an account number just because you have an account.
Typically, USCIS assigns an account number only in specific situations. You may receive an OAN if you:
- Filed a form online through a myUSCIS account
- Filed a paper form by mail, and USCIS processes it in their online environment
Your confirmation that USCIS has accepted your filing — whether you filed online or USCIS converted a paper filing to electronic processing — is the assignment of an IOE receipt number.
How Is the USCIS Online Account Number Used?
USCIS uses the number internally to connect your account activity with your cases. According to USCIS instructions, the number helps the agency manage electronic filings.
For applicants, the USCIS online account number is mainly used to link filings to an existing online account. You typically use it when:
- Including it on a paper-filed form to connect the case to your USCIS online account
- Adding or re-linking a paper-filed case inside your USCIS online account
However, if you do not know your number, USCIS states that you can leave the field unanswered.
Where to Find a USCIS Online Account Number
USCIS shares a USCIS online account number in only a few specific ways. If USCIS issued you a number, you can usually find it in one of three places: on an official USCIS notice, inside your USCIS online account for certain cases, or within documents stored in your account if the original notice is missing. The sections below explain each option and when it applies.
1. Check Your USCIS Online Account Access Notice
USCIS states that most applicants receive their online account number in a document called the USCIS Online Account Access Notice (as pictured above). This notice may be:
- Mailed to you, or
- Sent electronically, depending on how you receive USCIS communications
The USCIS online account number appears at the top of this notice. If you received this document, that is the most reliable place to find the number.
2. If You Lost the Notice or Never Saw It
Many applicants are unsure what happened to their notice. Fortunately, copies of notices are often stored inside your online account.
Applicants report success using this approach:
- Log in to your USCIS online account
- From the home page, open each case listed
- Select Documents for each case
- Look under USCIS Notices
- Review documents such as the Account Acceptance Notice
Look for the "USCIS Online Account Access Notice." If USCIS issued an online account number, it will appear on this notice.
3. If You Have an IOE Receipt Number
Applicants or petitioners who received an IOE receipt number may also be able to find their online account number inside their USCIS account profile.
To locate it:
- Log in to your USCIS online account
- Select Profile under the My Account menu
- Select a case that has an IOE receipt number
- View your USCIS online account number in the case details
If you do not see a Profile option, you likely do not have an online account number. USCIS links OANs to cases with IOE receipt numbers, which is why this method does not work for all applicants.
What If You Don’t Have a USCIS Online Account Number?
When you’re preparing a USCIS form, it can be unsettling to reach a question asking for a USCIS online account number and realize you don’t have one — or don’t know where to find it. This situation is common. USCIS clearly states that many applicants never receive this number. You likely do not have an online account number if:
- You filed all forms by mail
- USCIS has not linked your case to an online account
In these cases, USCIS instructs applicants to leave the field unanswered. Do not try to create a number or guess the number.
If you know you have an account number but cannot find it, you are safe to file a form without the number. Most importantly, USCIS will not delay the case because you didn't provide the OAN.
Do You Need a USCIS Online Account?
USCIS does not require all applicants to have an online account. Many forms still allow paper filing.
However, USCIS encourages online accounts because they:
- Speed up communication
- Reduce mailed notices
- Allow document uploads
Common Mistakes to Avoid
Applicants often make simple errors with this number. Avoid these mistakes:
- Entering your receipt number instead
- Guessing a number
- Assuming everyone has one
- Delaying filing because the field is blank
USCIS instructions are clear. If you don’t have the number, do not answer the question.
