How do I find my USCIS Online Account Number?

Your USCIS Online Account Number is different from your receipt number — it's tied to your personal myUSCIS account rather than to a specific form you filed.

If you already created a myUSCIS account, you can find this number by logging in at my.uscis.gov and checking your account profile page. If USCIS has linked a paper-filed case to your account, the number may also appear on certain notices they've mailed you.

If you haven't created a myUSCIS account yet, you don't need this number to check your case status — the receipt number from your filing notice (the one starting with three letters, like IOE, MSC, or EAC, followed by ten digits) is what you use for that. Creating a myUSCIS account is optional but does let you receive electronic notifications and, for some form types, respond to Requests for Evidence online instead of by mail.
