The 17-Character VIN Structure (ISO 3779 / NHTSA 49 CFR Part 565)
Understanding VIN architecture is fundamental for automotive software engineers and inventory managers. Every VIN is partitioned into three segments:
| Position | Segment Name | Standard Encoded Information |
|---|---|---|
| 1–3 | World Manufacturer Identifier (WMI) | Country of assembly, manufacturer name, manufacturing division. |
| 4–8 | Vehicle Descriptor Section (VDS) | Body class, engine type, transmission, series, restraint system. |
| 9 | Check Digit | Mathematical verification character calculated using a modulo-11 formula. |
| 10 | Model Year Code | Standardized 30-year cycle alphanumeric character representing model year. |
| 11 | Plant Code | Factory assembly facility identifier. |
| 12–17 | Vehicle Identifier Section (VIS) | Sequential vehicle assembly line serial number. |
Regulatory Compliance & DPPA Guidelines
Under the United States federal Driver's Privacy Protection Act (DPPA - 18 U.S.C. § 2721), vehicle history data provided for commercial purposes focuses strictly on the vehicle asset (odometer records, title brands, safety recalls, and technical specifications) rather than personal identifying information (PII) of registered owners.
