Decoding Pre-1981 Vins (Classic Cars)

Prior to 1981, vehicle identification numbers (VINs) were not standardized to the modern 17-character format. Classic cars from this era used shorter VIN codes that varied between manufacturers.

Where To Decode a Classic Car Vin

  • Vehicle Databases has a dedicated Classic API that can decode 5 to 13-digit VINs for vintage vehicles from 1912-1980. It returns details like year, make, model, transmission type, fuel usage, and engine specs.

  • CarMD offers both basic and premium VIN decoding options that can handle classic VINs, providing comprehensive vehicle details like specifications, battery info, and maintenance records.

5-Digit VINs

Some of the earliest classic cars had just 5-digit VIN codes. These provided basic information like:

  • 1st digit: Model year
  • 2nd digit: Manufacturer
  • 3rd digit: Body style
  • 4th-5th digits: Engine code

For example, a 1967 Ford Mustang with a 289 cubic inch V8 may have a VIN like 67F83.

13-Digit VINs

Many classic cars from the 1960s-1970s used a 13-character VIN format with the following breakdown:

  • 1st-3rd digits: Manufacturer code (e.g. 1G4 for Pontiac)
  • 4th digit: Body type
  • 5th digit: Engine code
  • 6th digit: Model year
  • 7th digit: Assembly plant
  • 8th digit: Body style
  • 9th-13th digits: Production sequence number

So a 1969 Pontiac Firebird with a 350 cubic inch V8 may have a VIN like 1G487XP123456.

Do Vin Numbers Have Zeros?

Yes, Vin Numbers use the numeric digit 0 (zero), but they do not use the letter O to avoid confusion with zeros.

The letters I, O, and Q are never used in VINs because they can be easily mistaken for the numbers 1, 0, and 9.

Why Check or Decode a Vin Number?

People may need to decode their Vehicle Identification Number (VIN) for several reasons:

  1. Verify Vehicle Information
    Decoding the VIN allows you to confirm the vehicle’s make, model, year, engine type, and other specifications provided by the seller. This helps ensure you are getting the exact vehicle as described.
  2. Check Vehicle History
    The VIN is used to access the vehicle’s history report, which can reveal past ownership, accidents, repairs, open recalls, and other important details. Decoding the VIN is the first step to obtaining this report.
  3. Validate Ownership
    Law enforcement and government agencies may need to use the VIN to confirm the vehicle’s ownership and rule out any suspicious activity like theft or fraud.
  4. Maintenance and Repair
    Mechanics and auto repair shops use the VIN to access the correct technical service bulletins, parts information, and repair procedures specific to that vehicle.
  5. Recall Identification
    Manufacturers issue recalls based on the VIN. Decoding it allows you to check if your vehicle is affected by any outstanding safety recalls.
  6. Insurance Purposes
    Insurance companies use the VIN when providing quotes, underwriting policies, or processing claims to accurately assess the vehicle’s risk factors and value.
  7. Fleet Management
    Companies that operate vehicle fleets need to use VINs to track maintenance schedules, fuel costs, financing details, and other aspects of fleet operations.


Every automobile has a unique 17-character Serial Number (VIN) that reveals its origin, features, and specifications through a process called decoding.

Online tools, such as the NHTSA and Edmunds VIN Decoders, offer a simplified and more accurate way to obtain detailed information about a vehicle’s manufacturer, model year, and other key aspects simply by entering your vin number.
