Random VIN Generator
Generate random NHTSA-compliant Vehicle Identification Numbers for testing and development — valid 17-character format with check digit.
How to Use the VIN Generator
Generate valid Vehicle Identification Numbers for automotive testing and development.
- Set quantity from 1 to 50 VINs to generate at once.
- Enable check digit validation to generate VINs with mathematically correct check digits (recommended).
- Click Generate to create random NHTSA-compliant VINs.
- Copy the results for use in automotive software testing, databases, or development.
What is a VIN?
A Vehicle Identification Number (VIN) is a unique 17-character code used to identify motor vehicles. Standardized by the International Organization for Standardization (ISO) in 1981, VINs provide detailed information about a vehicle's manufacturer, specifications, and production details.
Each VIN is divided into three sections: the World Manufacturer Identifier (WMI), Vehicle Descriptor Section (VDS), and Vehicle Identifier Section (VIS). The 9th character is a check digit calculated using a specific algorithm to validate VIN authenticity.
VIN Structure Breakdown
| Position | Section | Meaning |
|---|---|---|
| 1-3 | WMI | World Manufacturer Identifier (Country & Manufacturer) |
| 4-8 | VDS | Vehicle Descriptor (Model, Body Type, Engine, etc.) |
| 9 | Check Digit | Validation digit calculated from other characters |
| 10 | Model Year | Year of manufacture (letter or number) |
| 11 | Plant Code | Manufacturing plant identifier |
| 12-17 | VIS | Vehicle Identifier (Sequential production number) |
VIN Character Rules
VINs use only uppercase letters and numbers with specific exclusions to avoid confusion:
- Excluded letters: I, O, and Q (look too similar to 1 and 0)
- Allowed letters: A-H, J-N, P, R-Z
- Allowed numbers: 0-9
- Total characters: Always exactly 17
The check digit (position 9) is calculated using a weighted algorithm that multiplies each character's assigned value by a positional weight, then takes the remainder when divided by 11. The result is 0-9 or X (representing 10).
Common Use Cases
Automotive Software Testing: Test vehicle registration systems, insurance platforms, and dealership management software with valid VIN formats.
Database Development: Populate test databases for automotive applications, vehicle history services, and fleet management systems.
API Development: Test vehicle lookup APIs, VIN decoders, and automotive data services without using real vehicle data.
Form Validation: Test VIN input fields, validation logic, and user interface handling of 17-character codes.
Education & Training: Demonstrate VIN structure, check digit algorithms, and automotive data standards.
Important: Test Data Only
These VINs are randomly generated for testing purposes. While they follow valid NHTSA format and include correct check digits, they are not registered to real vehicles. Do not use these VINs to:
- Register vehicles with government agencies
- File insurance claims or reports
- Conduct vehicle history lookups on production databases
- Commit fraud or misrepresent vehicle information
These VINs are for development, testing, and educational purposes only.
