A vehicle identification number (VIN) is an alphanumeric code that uniquely identifies your vehicle. Etched and stamped into various areas of your car, each VIN includes a serial number as well as other coded information, like where and when it was manufactured. <\/p>\n\n\n\n

Often referred to as VIN numbers \u2014 though that\u2019s redundant, since the N already stands for \u201cnumber\u201d \u2014 today\u2019s structure is 17 characters long. Vehicles manufactured before 1981 may have fewer digits, though, or even follow a different structure than today\u2019s standard VINs.<\/p>\n\n\n\n

How the VIN came to be<\/h2>\n\n\n\n

Vehicle and engine identification numbers have been used for vehicle serialization, registration and fraud prevention purposes as early as the 1930s, though the concept was first standardized around 1954. VINs are required for motor vehicles, towed vehicles (such as RVs), motorcycles and mopeds.<\/p>\n\n\n\n

It wasn\u2019t until 1978 that the National Highway Traffic Safety Administration<\/a> (NHTSA) required a specific VIN structure and standardized format, starting with vehicle model years 1981 and beyond. NHTSA also mandates that no two vehicles manufactured within 30 years of each other can have the same VIN.<\/p>\n\n\n\n

What a VIN does<\/h2>\n\n\n\n

Your car\u2019s VIN acts as a unique identifier, which can be deciphered to tell you all about the vehicle. If you need to verify the car\u2019s age, features, trim or engine type, it will all be coded into the VIN.<\/p>\n\n\n\n

A VIN is used to track important information about each vehicle\u2019s history, too. Reporting services like Carfax and AutoCheck tie each car\u2019s VIN to alerts like manufacturer recalls. If you\u2019re buying a used car, checking the VIN can provide you with information that you may not get from the existing owner, such as title changes, owner history, odometer readings, service history and accident reports.\u00a0<\/p>\n\n\n\n

When selling your vehicle, providing the VIN can help a buyer confirm details and purchase with confidence. And if your vehicle \u2014 or a part of it \u2014 is stolen, VIN stamping can help with identification and recovery efforts. <\/p>\n\n\n\n

Why would an insurance company ask for my VIN?<\/h3>\n\n\n\n

You can expect an insurer to ask for your VIN when purchasing a new auto policy or adding a new vehicle to your existing coverage. This helps the insurance company accurately identify your vehicle and calculate its value, safety features and risk level. This information is used to confirm that the right vehicle is being insured, calculate premiums and prevent fraud. <\/p>\n\n\n\n

VINs are also used by state regulatory authorities and service providers to accurately evaluate vehicles, as well as track services or large repairs that are completed. <\/p>\n\n\n\n

Decoding your VIN<\/h2>\n\n\n\n

Today\u2019s VINs are globally standardized according to rules set forth by the International Organization of Standardization<\/a>, with each of the 17 positions serving a specific role. Together, this alphanumeric code allows you to not only identify your unique vehicle but also interpret the year, make, model, trim, key features and manufacturing plant location.\u00a0<\/p>\n\n\n\n

World Manufacturer Identifier (WMI), positions 1-3<\/h3>\n\n\n\n

The first three characters of today\u2019s VINs are known as the World Manufacturer Identifier<\/a> (WMI). <\/p>\n\n\n\n

The first character can be a number or letter, followed by a letter; together, they specify where the vehicle was built and which company made it. Vehicles manufactured in the United States will have an origin code of 1, 4, 5, 7F through 7Z or 70. Vehicles made in Japan will start with J and those made in China will start with L. The second character represents the manufacturer; for example, General Motors (GM) is usually denoted by G.\u00a0<\/p>\n\n\n\n

The third character can be used to represent the vehicle type (car, bus, RV, etc.) or a manufacturing division within that make \u2014 it\u2019s variable and depends on the manufacturer and country it\u2019s built in.\u00a0<\/p>\n\n\n\n

Vehicle Descriptor Section (VDS), positions 4 – 8 <\/h3>\n\n\n\n

The next five characters are the vehicle descriptor section, or VDS, and describe the vehicle\u2019s physical traits. Positions 4 through 8 indicate things like the model, body type, trim, transmission, restraint system and engine size of the vehicle. <\/p>\n\n\n\n

Check digit, position 9<\/h3>\n\n\n\n

The ninth character in your VIN is a \u201ccheck digit,\u201d or security character, designed to help detect fraudulent VINs. It is determined by a mathematical formula developed by the U.S. Department of Transportation<\/a> (DOT).<\/p>\n\n\n\n

Vehicle Identifier Section (VIS), positions 10 – 17<\/h3>\n\n\n\n

The remaining eight characters make up the vehicle identifier section, or VIS. Together, these act as your vehicle\u2019s true serial number. They help further identify your vehicle by model year and the specific plant in which it was manufactured, as well as when it came off the assembly line. <\/p>\n\n\n\n
