Where can I check a VIN for free?

Public databases like the U.S. [NHTSA](https://vpic.nhtsa.dot.gov/decoder/) offer free VIN checks, but the data is limited to recalls and basic identifiers. Auto.dev’s [VIN Decode API](https://docs.auto.dev/v2/reference/vin-decode) provides richer, structured specs, options, and pricing.

What happens if a VIN isn’t 17 characters long?

VINs shorter than 17 digits usually belong to vehicles manufactured before 1981, when the ISO standard was adopted. Modern vehicles must have a 17-character VIN.

Can a VIN reveal accident or service history?

Not directly. A VIN identifies the vehicle, but accident and service history comes from reporting services that tie data back to that VIN. APIs like Auto.dev focus on decoding specs and configuration.

Is the VIN format the same worldwide?

Most countries follow the ISO 3779 standard, but some regions may add local variations. The core 17-character format remains consistent for global interoperability.

Can VINs be faked or cloned?

Yes, fraudsters sometimes clone VINs from legitimate vehicles. Decoding a VIN and cross-checking against vehicle specs, plant codes, and history reports helps detect inconsistencies.
