VIN Validator

Validate 17-character VINs locally in your browser with length, character, and 9th-position check digit rules.

VIN Validator

A browser-based tool to strictly validate 17-character Vehicle Identification Numbers (VIN). It runs entirely locally and checks length, allowed characters, and the 9th-position check digit.

How to use

  1. Paste or type a VIN into the input box. Spaces and hyphens are supported.
  2. The tool uppercases and normalizes the input automatically, then validates length, allowed characters, and the 9th check digit in real time.
  3. Review the normalized VIN plus WMI, VDS, VIS, model year code, and plant code in the result area.

Features

  • 100% local processing with no vehicle data upload
  • Validates VIN character rules and disallows I, O, and Q
  • Breaks down WMI, VDS, VIS, and the check digit result

Why use this?

  • Quickly verify whether an entered VIN follows the standard
  • Catch length, character, and check digit errors in vehicle records
  • Free, fast, secure, and independent from third-party APIs
