What is a USCIS receipt number?
Quick Answer
A unique 13-character code (like IOE0123456789) assigned by USCIS when they receive your petition or application.
Detailed Explanation
When USCIS receives your immigration petition or application, they issue a receipt notice (Form I-797C) with a unique 13-character receipt number. The format is: 3 letters + 10 digits. Common prefixes: IOE (online filing), WAC (California), LIN (Nebraska), SRC (Texas), EAC (Vermont), MSC (National Benefits Center). This number lets you check case status online and is required for tracking in CaseTracker Auto.
