How Do I Perform a Classic Car VIN Check?

By | August 18, 2025

If you’ve just bought—or are considering buying—a vintage beauty, you’ll want to make sure it’s the real deal. One of the best ways to do that is by running a classic car VIN check. Unlike modern cars, where running a VIN is straightforward, classic cars can be a little tricky. That’s because VINs weren’t standardized in the U.S. until 1981, which means you’ll need a bit of detective work to uncover your classic’s history.

Let’s break down exactly how to find and use a classic car VIN, what to do with it, and where to look for reliable information.

Why a Classic Car VIN Check Matters

Classic cars aren’t just vehicles—they’re investments, passion projects, and pieces of history. Unfortunately, that also means fakes and “Frankenstein” builds (where parts from different cars are pieced together) are pretty common.

By running a VIN check, you can:

  • Verify authenticity
  • Confirm ownership history
  • Spot red flags like theft records or mileage fraud
  • Understand where and when your car was manufactured

It’s not just about peace of mind—it’s about protecting your wallet, too.

Where to Find the VIN on a Classic Car

Here’s where you’ll most likely find the VIN or other unique identifiers on your classic ride:

  • Dashboard – near the windshield on the driver’s side (sometimes visible from the outside)
  • Driver’s side wheel well
  • Under the steering column
  • On the firewall
  • Driver’s door edge or doorjamb sticker
  • Driver’s door hinge post
  • Frame rail (driver or passenger side)
  • Engine block (keep in mind engines may have been swapped over time)

🔎 Pro tip: Don’t stop with the VIN. Classic cars often have trim tags, engine codes, or axle stampings that can help you verify originality.

Check the Paperwork Too

Sometimes the best clues aren’t on the car—they’re on the documents. Look for VINs or serial numbers on:

  • Title documents
  • Registration paperwork
  • Insurance policies
  • Bills of sale
  • Maintenance and repair records

Always cross-check these documents with the numbers stamped on the car. If they don’t match, that’s a red flag.

The Problem with Older VINs

Here’s where things get tricky:

  • Before 1981 – VINs weren’t standardized. Each manufacturer had its own system.
  • Mid-1950s and earlier – Cars didn’t even have proper VINs. Instead, they often had serial numbers stamped on engines or major parts.

This means two cars could technically share the same identifier. That’s why a classic car VIN check takes more digging than a modern one.

Does a VIN Report Affect Classic Car Insurance?

Good news: a VIN history report won’t directly change your insurance rates. However, insurance providers do view verified cars more favorably. If you can prove your classic is authentic and well-documented, that can help establish its collector value.
