Most vehicles seem the same to the ordinary eye, especially if they are the same make and color.
So, is there a difference between your car and the one stuck next to you in traffic?
The answer to this question is the Vehicle Identification Number (VIN) or a chassis number.

What is a VIN number?
A chassis number is a unique code given to each vehicle by manufacturers. It acts as a fingerprint; no two vehicles can have the same code.
Chassis number features
- This car ID system complies with two standards: the US standard FMVSS 115 and the ISO (International Standard Organization 3779 2009)
- The code has 17 characters.
- The characters are made up of numerals and letters, excluding letters Q, I, and O.
- Each character contains information regarding the vehicle.
- The WMI (World Manufacturer Identifier) code makes up the first three characters of the code.

In Australia, NEVDIS (National Exchange of Vehicle and Driver Information System) maintains a database for each vehicle’s VIN in the country.
NEVDIS ensures each vehicle gets a unique code, and this prevents theft and fraud.
The data is easily available to the general public through the Document Verification Service (DVS) and the PPSR (Personal Property Security Register).
Classifications
ADR (Australian Design Rules) referring to ISO 3780 and 3779- These are Australia’s standards for vehicle emissions, safety, and theft resistance.
FMVSS (Federal Motor Vehicle Safety Standards) 115, used in Canada and USA- These are federal regulations governing performance, design, durability requirements, and vehicles’ construction.
ISO (International Organization of Standards) standard 3779, used by most countries, including countries in Europe.
SAE (Society of Automotive Engineers) J853, similar to ISO standard – Rates vehicles horsepower.
The information contained in the VIN number.
The following is information found in the code:
- Engine specifications
- Sequential serial number
- The manufacturer’s WMI
- Where the vehicle was built
- Safety equipment
- Model year
- Technical specifications and vehicle’s features
Where to find the VIN Number
You can find the chassis number by:
- Looking at the driver’s side on your vehicle’s dashboard -To view it easily, stand on the outside of the car and check on the corner where the windshield meets the dashboard.
- The front part of the engine under the hood
- Check the information label on the driver’s doorjamb
- Look under your spare tire in the trunk
- Above the auto tire on your rear wheel
- Car’s registration and title
- Insurance card or insurance policy.
How to read the number

Example: 2C4EF4UC3JT416219
First character – 2, this is part of the WMI (World Identification Manufacturer) code. This number shows the country of origin
- A-H refers to Africa
- J-R (excluding O and Q) refers to Asia
- S-Z refers to Europe
- 1-5 refers to North America
- 6 or 7 refers to Australia or New Zealand
- 8 or 9 refers to North America
The second and third character, C4- This identifies the manufacturer
- C – Chrysler
- 4 – Buick
- J -Jeep
- 6 – Cadillac
- T – Toyota
The fourth character to the eighth character – EF4UC contains the general specification of the car’s body style, engine code, safety equipment, emission code, and model.
Ninth character – 3 is the check digit and is used to prove the chassis number.
The tenth character – J, indicates the year model. It starts with A to indicate 1980, then switches to 1-9 to indicate the year 2001 to 2009, then switches back to the alphabet (A) from 2010.
The eleventh character – T, tells which factory assembled the vehicle.
The twelfth to seventeenth character – 416219 is the SSN (sequential serial number). These six digits tell well along into a production run was the car manufactured.
This is important information, especially to collectors who prefer limited edition vehicles such as the BMW I Series M Coupe.
VIN number check digit calculation

The character on position 9 of the code is referred to as check digit.
This digit, always a number, is a mandatory requirement in every vehicle to prove the vehicle identification number.
To validate it, the manufacturer multiplies all the characters, except the ninth digit. The answer is then divided by 11.
If the remainder is equal to the ninth digit, then the VIN is genuine.
The calculation process is quite complex, especially if you are not a mathematics nerd, and that’s where scanning comes in handy.
VIN scanning
Each car manufactured since 1981 has a chassis number in a bar code format. Knowing the information decoded from the barcode helps you to authenticate your car.
The information includes accident history, service history, and manufacturer details.
Your mechanic can use this information to order the right accessories and parts for the vehicle.
You can easily get the car’s details by scanning the barcode. You can use a barcode scanner, OBD (on-board diagnostics) system, or digital camera.
Currently, there are scanning apps available that you can use to get these details.
These apps can be downloaded into one’s smartphone, and they include VIN Barcode Scanner, First Call VIN Scanner, VinAudit.com, VINfo VIN Decoder, and VIN Viper VIN Scanner.
Barcode scanning is important to car dealers, body shops, and repair shops because of its accuracy and speed.
You can be quickly and accurately identified if you are a repeat customer.

Bottom line
Your car’s VIN number is its fingerprint, birth certificate, or Social Security Number.
It carries information on the country of origin, manufacturer’s WMI, model year, safety information, and the uniqueness of the car.
This automobile chassis number is to protect your car not only from theft but also from fraud. It also tells your car’s history.
You can easily get it by checking under the spare tire, on the manufacture’s database, on the car’s registration and title, and on the driver’s doorjamb.
Use your phone, digital camera, or barcode scanner to read this code.
Important notes
Always scan the number before you buy the vehicle, especially when buying a used car.
If the chassis number is not similar to the one on the registration document, do not make the purchase.
