# VIN Validator

> Validate any VIN instantly, no database needed: the check digit is arithmetic fixed by 49 CFR 565.15. See the worked math position by position, what each character carries, and the model-year code read both ways.

## What this tool does

Enter a 17-character VIN and the page verifies it entirely in your browser — no lookup, no database, no network request. Position 9 of every VIN is a check digit computed from the other sixteen characters under 49 CFR 565.15; the tool shows the worked arithmetic (transliteration values, weights, products, the remainder mod 11), labels what each of the 17 positions carries, reads the model-year code at position 10 both ways round its 30-year cycle, and names the world region encoded by the first character.

## Why it matters

A VIN that fails its check digit cannot be a real VIN — one mistyped character is caught before you pay for a report that cannot exist, and a listing whose VIN fails arithmetic is a listing to question. It is the only VIN check that needs no records at all.

## Limits worth knowing

A valid check digit proves the number is well-formed, not that a vehicle exists, matches the listing, or has a clean record. Decoding what the number says is the VIN Check tool's job; what happened to the vehicle afterwards is a records question.
