VIN check Excel formula alternative

Client

Spreadsheet MOD formulas for VIN check digits break on transliteration edge cases and locked-down corporate laptops. This page is a formula-free alternative—paste and read pass/fail in the browser.

When to skip spreadsheet formulas

For bulk columns, paste one VIN per line. For single checks, paste once. No VBA, no add-ins, no IT approval—just browser mod-11.

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.
