Fiat & Alfa Romeo Build Sheet by VIN

What is a build sheet?

A build sheet is the factory's record of how a specific vehicle was assembled. For Fiat and Alfa Romeo it ties the VIN to the model year, market, body style, engine family, trim, and the equipment the car was originally built with.

It's the most reliable way to confirm how a used Fiat 500, 124 Spider, Alfa Romeo Giulia, Stelvio, or Tonale was configured — more dependable than a badge or a seller's description.

What the build sheet shows

The build sheet covers powertrain, trim, body style, exterior and interior colors, wheels, packages, and factory options — the details that explain why two cars with the same model name can feel very different.

For performance models, it helps separate genuine mechanical packages from appearance trims, which matters on Quadrifoglio, Veloce, and Abarth-style configurations.

Trims & packages

One package name can include several smaller features — a comfort, appearance, or driver-assistance group can change the practical value of the car. Reading the build sheet carefully tells you what the vehicle actually carries.

Factory data should not be confused with later modifications: wheels, audio, badges, and trim pieces may have changed since delivery, so use the build sheet alongside photos and an inspection.

Where to find your VIN

Your VIN is a unique 17-character code. You can read it from any of these places — each gives the same number:

• Base of the windshield, driver's side. Look at the lower-left corner of the glass from outside.
• Driver's door-jamb sticker. Open the driver's door and check the frame.
• Registration, insurance card, and title. Every ownership document carries the VIN.

Which vehicles are supported

The lookup covers Fiat (500, 500X, 124 Spider) and Alfa Romeo (Giulia, Stelvio, Tonale, and more). Enter the VIN and the tool retrieves the factory build sheet for that vehicle.

Coverage depends on the factory record being on file. There's no account, nothing to install, and every lookup is free.

How to look up your build sheet

Find your 17-character VIN, type it into the box at the top of this page, and select "Look Up Build Sheet."

The tool retrieves the factory build sheet — usually within a few seconds — and shows it inline. If no build sheet is on file for that VIN, you'll see a short message instead.
