• Free VIN checkPaste a 17-character VIN to decode the car and see official US safety recalls — free, with no account. Below: exactly what a free VIN check covers, and where a full US history report goes further.
• US VIN checkPaste a 17-character VIN. We'll tell you right away whether it's a US-market car and show the manufacturer behind the code — the first step before importing a car from the USA.
• Miles to kmUS cars show distance in miles and speed in mph. Convert either way below — then check the car's VIN, because the number on the dash means nothing if the odometer was rolled back.
• VIN validatorCheck whether a VIN is valid. We verify the length, the characters and the ISO 3779 check digit, and show the region of origin. Then decode the full VIN in one click.
• Recall checkEnter a VIN to check a car for open safety recalls from official records — free, no sign-up. A recall means the maker found a safety defect and must repair it, almost always for free.
• Mileage checkEnter a car’s mileage and year. We compare it to the typical distance for a car of that age to flag suspiciously low readings — the number-one sign of odometer rollback.
• Motorcycle VINEnter a motorcycle VIN to decode the make, model, year and engine — free, no sign-up. A bike VIN is 17 characters, the same standard cars use.
• VIN codesThe first characters of a VIN tell you who made the car and where. Look up a manufacturer code (WMI), check the country codes, and decode your full VIN.
• Fault codesGot a check-engine light? Look up your OBD-II fault code for a plain-language meaning, the common symptoms, the most likely causes and what to do next.
