A decal number is another term for a vehicle's VIN (Vehicle Identification Number), which is a unique 17-character code assigned to every car, truck, and motorcycle. Think of it as your car's fingerprint, used for official registration, title, and insurance purposes. The term "decal" comes from the fact that this number is often displayed on a small, permanent sticker or metal plate affixed to the vehicle, most notably on the dashboard near the windshield. It is the primary identifier used by law enforcement, DMV offices, and insurance companies to track a vehicle's history and legal status.
The VIN is not just a random sequence; it's a coded string that reveals key details about the vehicle. The first three characters are the World Manufacturer Identifier (WMI), which tells you the country of origin and the manufacturer. The following six characters describe the vehicle's attributes, like model, body style, and engine type. The ninth character is a check digit used to verify the VIN's authenticity. The tenth character indicates the model year, and the eleventh shows the plant where the car was assembled. The final six digits are the unique serial number.
You'll find the VIN in several locations. The most common is on the driver's side dashboard, visible through the windshield. It's also stamped on the vehicle's frame, usually on the driver's side doorjamb (on a sticker that also includes tire pressure information), and on important documents like the title and registration. You need this number for almost every official transaction, from getting a quote on car insurance to running a vehicle history report before buying a used car. It's the key to uncovering past accidents, ownership changes, and recalls.
