How to Decode a VIN with ChatGPT
Decode a VIN for Full Vehicle Specifications with ChatGPT and ToolRouter. Get formatted VIN decode reports for insurance, fleet management, or parts sourcing.
Tool
Use ChatGPT with Vehicle Data to decode a VIN and produce a formatted specification report. ChatGPT is well-suited when the decoded VIN data needs to be organized into a clear document — an insurance record, a parts reference sheet, or a fleet entry with full vehicle details.

Steps
Once connected (see setup above), use the Vehicle Data tool:
- Provide the VIN and specify how the output will be used — insurance record, parts sourcing, or fleet management.
- Ask ChatGPT to run `decode_vin`, `decode_wmi`, and `vehicle_specs` via `vehicle-data`.
- Have ChatGPT produce a formatted specification sheet with manufacturer, production details, engine, and trim.
- Ask for the output in your required format — table, insurance field set, or parts reference list.
Example Prompt
Try this with ChatGPT using the Vehicle Data tool
Use vehicle-data to decode VIN: WBA3A5G59DNP26082. Run decode_vin, decode_wmi, and vehicle_specs. Produce a specification sheet formatted for an insurance record with: VIN, manufacturer, country of production, model year, model, engine type, fuel type, trim level, and MSRP if available.
Tips
- Format the output for the specific downstream system — insurance fields differ from parts reference fields.
- Include country of production alongside manufacturer — these differ for vehicles assembled under license.
- Ask for MSRP if available — it is often encoded in production data and useful for insurance valuation.
