Dealership VIN intake check

Client

Dealership intake desks retype VINs into DMS and insurer portals all day. Intake check catches mod-11 failures before those systems reject the row—no integration with dealer management software.

Desk workflow

Copy from customer title or door jamb, paste here, confirm pass, then enter the same string into DMS and lender systems—one typo caught early avoids end-of-day reconciliation.

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

Common use cases

  • F&I desk sanity check before retyping into lender portals.
  • Used-car intake comparing windshield to auction sheet.
  • Train new sales staff with a bookmarkable validator.

Common mistakes to avoid

  • Skipping physical sticker verification on high-value trades

    Checksum pass does not detect VIN cloning—inspect labels and embossing.

  • Assuming DMS validation replaces mod-11 pre-check

    Early catch saves rework when portals return opaque errors.
