How to Decode a Chinese VIN

The 17-digit Chinese VIN follows a structured format that reveals detailed information about the vehicle. Let's break down each section:

World Manufacturer Identifier (WMI) - First 3 Characters:

• 1st digit: Geographic region (L for China)
• 2nd digit: Manufacturer identifier
• 3rd digit: Vehicle type or division

Vehicle Descriptor Section (VDS) - Characters 4-9:

• Characters 4-5: Body style and engine type
• Character 6: Restraint system and transmission
• Characters 7-8: Model series and variants
• Character 9: Check digit for verification

Vehicle Identifier Section (VIS) - Characters 10-17:

• Character 10: Model year
• Character 11: Manufacturing plant
• Characters 12-17: Sequential production number

Example Breakdown - BYD Electric Vehicle:

LGX | N5U | B28 | 9 | M | A123456

LGX     →  BYD manufacturer code
N5U     →  Vehicle attributes
B28     →  Model specifications
9       →  Check digit
M       →  Manufacturing plant
A123456 →  Production sequence

Special Considerations for Chinese VINs:

• Electric Vehicle Coding: Additional characters indicate battery type and motor configuration
• Export Models: May have market-specific identifiers
• Joint Venture Vehicles: Special manufacturer codes for partnerships
