Form 2290 reports each vehicle by its 17-character Vehicle Identification Number (VIN). Entering it correctly is critical, because a single wrong character is the most common reason a Schedule 1 has to be corrected.

Where to find your VIN

  • The vehicle title and registration documents.
  • The driver-side door jamb sticker.
  • The lower corner of the windshield on the driver's side.
  • Your insurance card or policy.

Reading it without errors

A VIN is exactly 17 characters and never uses the letters I, O, or Q (to avoid confusion with 1 and 0). Copy it from a reliable document rather than from memory, then read it back character by character before you file. You can validate it first with the VIN checker.
