How this service works
Validate a 17-character vehicle VIN check digit and decode region, manufacturer code and model-year candidates.
Output
Returns a JSON object with: a verdict (valid/invalid), the expected check digit, the normalised VIN, the WMI code, region, plant code, serial segment, an array of possible model years, a human-readable summary, reasons for any failure, a degraded flag if data sources were unavailable, a notChecked list, a source and asOf timestamp, and a disclaimer.
Example use cases
Pre-purchase vehicle VIN check
“Before I buy this used car, can you verify the VIN 3VWFE21C04M000001 — is the check digit valid, where was it built, and what model years could it be?”
Detecting a fraudulent VIN listing
“I think this VIN might be fake — can you run a check on 1FTFW1ET0EKE12345 and tell me if the check digit passes, what region it claims, and what the expected digit should be if it fails?”
Automotive data pipeline enrichment
“I have a VIN 5YJSA1DN5DFP14947 from our inventory system — validate its check digit and decode the WMI, plant code, and model-year candidates so I can enrich the record.”
Technical details
Endpoint
GEThttps://id-validators.x402tookit.com/vin-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify the structural integrity and check digit of a 17-character VIN and also want decoded metadata (region, WMI, model year candidates) in a single call. Prefer it over generic VIN lookup services when you need lightweight, pay-per-call validation without a subscription, or when you are building an automated pipeline that processes many VINs cost-efficiently at $0.02 per call.
Side effects
- VIN is not exactly 17 characters — returns invalid verdict with reasons
- VIN contains illegal characters (I, O, Q) — returns invalid with explanation
- Check digit does not match computed value — verdict is invalid with expected digit provided
- Unknown WMI — region/manufacturer fields may be null with degraded flag set
- Network or data-source outage — degraded flag set, partial results returned
- Missing required query parameter id — likely HTTP 400 error
