What does each character in a VIN mean?

Characters 1-3 = Manufacturer (WMI), 4-9 = Vehicle attributes (VDS), 10 = Model year, 11 = Plant code, 12-17 = Serial number.

How do I check if a VIN is valid?

A valid VIN is exactly 17 characters, doesn't contain I, O, or Q, and passes the check digit verification at position 9.

Can I check for open recalls with a VIN?

Yes, our decoder checks US NHTSA recall data. Canadian buyers should also check Transport Canada.

What information can I get from a VIN?

Manufacturer, make, model year, country of origin, engine type, body style, plant code, and recall history.

Is VIN decoding free?

Yes, our VIN decoder is completely free. No sign-up, no limits, no hidden fees.

Can I decode a 16-character VIN?

No, vehicles manufactured after 1981 use 17-character VINs. Older vehicles may have shorter VINs.

Used-Car Scam Checker

Name: VIN Decoder
Author: usecos.app Research & Engineering

Use this US used-car scam checker as a buyer-safety workflow before meeting, travelling or sending a deposit. It starts with VIN/listing consistency and routes deeper questions to official records.

Scope

United States used-car due diligence

Use this for

VIN screen, risk flags, official-source follow-up and buyer workflow

Not a substitute for

A VIN decoder is not a vehicle-history report, lien search, inspection report, ownership record or insurance-claims search.

Direct answer

A used-car scam screen should pause any deal where the seller will not provide the VIN, pressures for a deposit, avoids title paperwork, uses mismatched photos/documents, refuses inspection or gives inconsistent year/make/model/odometer details. Use the VIN listing match checker first, then verify title/history, recalls and seller identity.

Methodology notes

The page uses the shared usecos VIN decoder, which validates 17-character VIN format, excludes I/O/Q characters and checks the position-9 check digit where possible.
NHTSA vPIC manufacturer and model data comes from manufacturer-submitted 565 records and may be incomplete for unusual, imported, pre-1981 or specialty vehicles.
Recall data can differ between US and Canadian campaigns, so Canadian buyers should check Transport Canada and the manufacturer in addition to NHTSA.
US title, brand, odometer, theft, accident, lien and salvage checks require NMVTIS, state DMV/title records, approved data providers, inspection, seller documents or paid reports; usecos does not claim to replace them.
NHTSA vPIC and recall sources are US official sources, but a decoded VIN or recall result is only one part of used-car diligence.

Common mistakes

Treating a valid VIN decode as proof of clean title, no lien, no theft record, no accident history, no odometer rollback or no salvage brand.
Sending a deposit before matching the listing, physical VIN, title paperwork and seller identity.
Using a single recall or history source as the final answer without checking manufacturer, state, NMVTIS or inspection records where relevant.

Limitations

A VIN decoder is not a vehicle-history report, lien search, inspection report, ownership record or insurance-claims search.
Model, trim, engine and plant details can be incomplete when manufacturer-submitted vPIC fields are blank or ambiguous.
Vehicles built before the modern 17-character VIN standard, grey-market imports, incomplete vehicles and some specialty manufacturers may need manual checks.
Does not provide an NMVTIS report, state title record, lien search, theft search, accident history, odometer certification, salvage determination, legal opinion or inspection.
US state title, dealer disclosure, warranty and private-sale rules vary; confirm the current rules in the state where the vehicle is titled or sold.
