Verify VIN online

Client

Verify VIN online usually means checksum validation before trusting a copy-paste—not a government or insurer lookup. This page runs mod-11 locally so digits never leave your tab.

What online verify means here

Characters stay on your device. The page applies published transliteration tables and mod-11 weights—same public rules NHTSA documents for the ninth position.

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.
