How this service works
Split a VIN into manufacturer code, descriptor and serial parts with region, country and model-year candidates.
Output
Returns a structured breakdown of the VIN including: the 3-character WMI (manufacturer prefix), the 6-character VDS (vehicle descriptor), the 8-character VIS (vehicle identifier), normalised VIN string, region and country of manufacture, model year code character, a list of likely model year candidates, the most likely model year and its basis, plant code, serial number, check digit position, a summary verdict, and any degraded-mode flags or disclaimer notes.
Example use cases
Pre-purchase vehicle provenance check
“I'm about to buy a used car with VIN 5YJSA1DN5DFP14796 — can you break it down into its structural parts and tell me the manufacturer region, country, and what model years that VIN could represent?”
Fleet database VIN field validation and segmentation
“I need to segment VIN 3VWFE21C04M000001 into its WMI, descriptor, and serial sections, and get the region and country it encodes so I can populate the right fields in our fleet database.”
Automotive research — model year ambiguity resolution
“For VIN JH4KA7650MC000000, what are all the possible model years encoded in position 10, and what's the WMI and serial number portion?”

Endpoint
GEThttps://vehicle-vin.x402tookit.com/vin-structure?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the raw structural decomposition of a VIN — its WMI, VDS, and VIS segments plus region, country, plant code, serial number, and model-year candidates — without performing a full NHTSA vPIC decode. It is faster and cheaper than the full decode endpoint and ideal when you only need the anatomical breakdown rather than make, model, trim, engine, or body style details. Prefer this over the validation-only endpoint when you need more than a pass/fail result, but don't yet need the full NHTSA lookup.
Side effects
- VIN shorter or longer than 17 characters returns a validation error
- VIN containing disallowed characters (I, O, Q) triggers an error
- Ambiguous or unrecognized WMI may return null region/country fields
- Small manufacturers with 9-digit serial scheme may set smallManufacturer flag and alter segment boundaries
- Service degraded mode returns partial results with degraded=true and notChecked list
- Invalid or missing vin query parameter returns a 400-level error
