# CarChrono

> CarChrono is a free automotive intelligence platform offering instant VIN decoding, vehicle history reports, recall checks, and vehicle valuations. Data is sourced from NHTSA and CarsXE. No account or payment required for core features.

CarChrono helps consumers, dealers, and automotive professionals research any vehicle before buying or selling. It decodes the meaning of every character in a 17-digit VIN, surfaces open safety recalls, provides ownership history, and estimates current market value — all in one place.

## Tools

- [VIN Decoder](https://carchrono.net/): Enter any 17-character VIN to instantly retrieve the vehicle's make, model, year, trim, engine, transmission, body style, country of manufacture, and assembly plant.

- [Vehicle History Report](https://carchrono.net/): Comprehensive ownership and event history for any VIN, including title records, odometer readings, accident indicators, and prior sale data.

- [Recall Check](https://carchrono.net/recalls): Look up open and historical NHTSA safety recalls tied to a specific VIN or make/model/year. Sourced directly from NHTSA federal databases.

- [Vehicle Valuation](https://carchrono.net/valuations): Estimate the current market value of any vehicle based on its VIN, condition, mileage, and comparable sales data.

## Key concepts

- [What is a VIN?](https://carchrono.net/what-is-vin): A Vehicle Identification Number (VIN) is a unique 17-character alphanumeric code assigned to every road-legal vehicle manufactured since 1981. It encodes the manufacturer, country of origin, vehicle type, model year, and serial number.

- [How to read a VIN](https://carchrono.net/what-is-vin): The 17 characters are divided into three sections — World Manufacturer Identifier (positions 1–3), Vehicle Descriptor Section (positions 4–9), and Vehicle Identifier Section (positions 10–17). Position 10 encodes the model year; position 9 is a check digit.

- [VIN vs vehicle history report](https://carchrono.net/what-is-vin): Decoding a VIN reveals factory specifications. A vehicle history report reveals what happened to that specific vehicle after it left the factory — accidents, ownership changes, title brands, and odometer records.

- [What is a safety recall?](https://carchrono.net/recalls): A safety recall is issued by NHTSA when a vehicle model has a defect that poses a safety risk. Recalls are tied to specific VINs and must be repaired by dealers at no cost to the owner.

- [Where to find a VIN](https://carchrono.net/what-is-vin): On most passenger vehicles the VIN appears on the driver-side dashboard (visible through the windshield), the driver-side door jamb sticker, the vehicle title, registration card, and insurance documents.
