USCIS Receipt Number
A 13-character identifier assigned to each USCIS case (e.g., MSC2090123456).
The receipt number begins with three letters indicating the service center (MSC, SRC, EAC, WAC, NBC, IOE, LIN, YSC) followed by the fiscal year and a sequential case number. It is the primary way to look up case status online.
