VIN (17 characters)
Found on the dashboard (driver side), door jamb sticker, or registration.
Decoded VIN

Built inChina
Model year (pos 10)1987 / 2017
Check digit (pos 9)Mismatch
Serial (pos 12-17)123456

Decoding steps

  1. 1WMI (1-3): LSG — manufacturer/region code
  2. 2VDS (4-9): KB54E0 — vehicle attributes (body/engine, maker-specific)
  3. 3VIS (10-17): HA123456 — model year, plant, serial
  4. 4Position 10 = H → model year 1987 or 2017 (30-year code cycle)
  5. 5Check digit: Σ(value×weight) mod 11 = 9; position 9 is 0 → MISMATCH (VIN may be mistyped or fake)
  6. 6Position 1 = L → built in China

VIN structure (ISO 3779): positions 1-3 WMI identify country and maker (L.. = China, e.g. LSG = SAIC-GM); 4-9 VDS describe model/body/engine per each maker's own scheme; 10 is the model year in a 30-year cycle; 11 is the assembly plant; 12-17 the serial. The check digit (position 9) is mandatory in North America — Chinese-market VINs usually follow it too, but a mismatch on an import is a red flag for a cloned or mistyped VIN. Positions 4-8 full decoding requires maker-specific tables not covered here.
