What is a Classic AC VIN?

A VIN, or Vehicle Identification Number, it's a unique number that identifies every vehicle on the road. For modern cars, the VIN is standardized with 17 characters, thanks to regulations that started in 1981. But when it comes to classic AC cars, things are a bit different.

Classic AC vehicles, which were produced long before the 1981 VIN standard, often have shorter VINs, sometimes just 5 to 14 characters long. These older VINs (or chassis numbers) don't follow the same 17-character rule that modern cars do, and that's because they were built before that system was put in place. AC also used proprietary formats for these numbers, meaning they had their own structure to identify each car.

The classic AC VIN decoder helps you decode the classic VIN and get the detailed information on the vehicle through the classic history report.

Where to Find the VIN in a Classic AC Car?

Finding the VIN on a classic AC car can take a little detective work, but it's worth it to confirm the car's identity. Here are the most common places to check:

Dashboard (through the windshield): Start by checking the bottom corner of the dashboard on the driver's side, where it meets the windshield. The VIN number should be visible through the glass.
Driver's Side Doorjamb: Open the driver's door and take a look at the frame or doorjamb. You should find a sticker or metal plate with the VIN number.
Firewall (Engine Bay): In many AC models, the VIN number is stamped on a metal plate attached to the firewall, the metal barrier separating the engine compartment from the cabin.
Engine Bay (Under the Hood): Look around for additional identification tags or a stamped VIN plate under the hood. Sometimes, it's located near the engine block or radiator support.
Vehicle Frame: On certain models, AC stamped the VIN directly onto the vehicle's frame, usually near the front suspension or on the chassis rail.
Other Locations: Keep an eye out for secondary VIN number tags on the transmission housing, trunk floor, or inside the footwell.

Check Your Paperwork: If you have the car's old registration, title, or insurance documents, the VIN number should be listed there.

Brief History of Classic AC

Despite ownership changes and quiet periods, AC is revived multiple times, and today the name lives on with continuation cars and modern models inspired by its classic heritage.

1901 – AC Cars traces its origins back to Auto Carriers Ltd., one of Britain's oldest motoring names.
Early decades – The company grows by building light cars and sports tourers, earning a reputation for small, well-built British machines.
1950s – The AC Ace sports car is launched, a lightweight, elegant roadster that becomes the brand's signature model.
1960s – The Ace chassis and body are shipped to the U.S., where Carroll Shelby fits American V-8 power, creating the legendary Shelby Cobra.
1950s–1970s – AC also produced the refined Aceca coupe, the Greyhound, the powerful 428 Frua, and, later, the mid-engined 3000ME.
