How this service works
Vehicle Identification Number validation (ISO 3779): 17-char structure, check digit (position 9), WMI/VDS/VIS decomposition and model-year code.
Output
Returns whether the 17-character VIN is structurally valid per ISO 3779, whether the check digit at position 9 passes, and a decomposition of the three VIN sections: WMI (World Manufacturer Identifier, chars 1–3), VDS (Vehicle Descriptor Section, chars 4–8), and VIS (Vehicle Identifier Section, chars 10–17), along with the decoded model-year code.
Example use cases
Pre-purchase vehicle inspection workflow
“I'm about to buy a used car and the seller gave me the VIN — can you validate it's a real legitimate number and break down what manufacturer, model year, and specs it represents?”
Insurance claims VIN verification process
“We have a claim for a vehicle with VIN 5TDJKRFH8LS123456. Before processing, I need to make sure this VIN is structurally valid and that the check digit passes our compliance checks.”
Automotive inventory management system
“I'm importing a batch of vehicles into our lot management system and need to validate each VIN to make sure they're properly formatted and decode the model year for our catalog. Can you check this one — WBADO6342VBC812345?”
Technical details
Endpoint
GEThttps://api.aventtech.com/validate/vin?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate or decode a VIN against the ISO 3779 standard, particularly when you require check-digit verification and structured WMI/VDS/VIS decomposition. Prefer this over manual regex checks when authoritative structural validation and model-year decoding are needed in an automated pipeline.
Side effects
- VIN shorter or longer than 17 characters returns validation error
- Invalid check digit returns failure with expected vs actual digit
- Malformed input (non-alphanumeric characters) returns parse error
- Missing 'vin' query parameter returns 400 bad request
- Payment not provided or insufficient returns 402 Payment Required
