VIN check

Client

VIN check is the head term for validating a North American-style 17-character vehicle identification number before fleet intake, insurance forms, or OCR cleanup. Paste below for local mod-11 arithmetic and WMI/year/plant field split—no live registry query.

How to run a VIN check

Copy 17 characters from the windshield, door jamb, or title scan. Paste into the field—spaces and hyphens are stripped. Read check pass/fail, expected ninth symbol, WMI prefix, model-year code, and sequential tail.

Privacy: parsing runs only in your browser. This page does not query DMV, insurance, or manufacturer databases—only the published mod-11 rule for the ninth character.

After removing spaces and hyphens, the frame must be exactly 17 characters. Letters I, O, and Q are forbidden everywhere. Position 9 (index 8) is the check symbol: decimal 0–9 or X for remainder ten. Each symbol maps to a numeric value, is multiplied by a fixed weight for its position, products are summed, and sum mod 11 must equal the check symbol’s value (X → 10).

Result

Passes check digit — weighted sum mod 11 is 10; expected X.

  • WMI (positions 1–3): 1HG
  • Attributes (4–8): BH41J
  • Check (9): X
  • Model year code (10): M
  • Plant (11): N
  • Sequential (12–17): 109186

Common use cases

  • Confirm windshield sticker digits match door-jamb copy before filing internal fleet spreadsheets.
  • Batch-check VIN columns in logistics CSVs before ERP import.
  • Train staff why one ninth-position typo fails mod 11 even when letters look plausible.

Common mistakes to avoid

  • Assuming checksum pass proves title or theft clearance

    Only the algebraic relationship between characters is verified here.

  • Typing I, O, or Q from handwritten notes

    Those letters are forbidden in standardized VINs to avoid digit confusion.
