Bulk VIN check

Client

Bulk VIN check helps fleet and auction teams scan many frames from CSV or spreadsheet paste. The main tool accepts multi-line input—use this page intent for bookmarking batch workflows.

Batch paste workflow

Export a single column from spreadsheet software, paste into the input, and read per-line results. No data is uploaded for server-side batch processing.

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.
