Your VIN and your policy

Where to find it

• On the dashboard at the base of the windscreen, visible from outside
• On the driver's door jamb sticker
• On the vehicle title and registration
• On your insurance declarations page
• In the vehicle's own documentation

What it tells an insurer

The VIN identifies the manufacturer, model, model year, engine, body style, and often factory-fitted safety equipment.

That matters because those things affect both the rate and what a claim would cost — two vehicles that look identical can have different engines, trim and safety features.

Why an error causes trouble

A policy written against the wrong VIN describes a vehicle you don't own. At claim time that discrepancy has to be resolved, which at best delays the claim and at worst creates a dispute about what was actually covered.

It also means the rate may have been calculated on a different vehicle than the one you drive.

Check the VIN on your declarations page against the vehicle itself. It takes a minute and almost nobody does it.

Before buying a used car

• Run a vehicle history report using the VIN
• Check for a salvage, rebuilt or flood-damage title — these affect insurability and value
• Confirm the VIN on the vehicle matches the title and every sticker
• Check for outstanding recalls
• Be wary if any VIN plate looks altered or missing

Salvage and rebuilt titles

A vehicle with a salvage or rebuilt title is harder to insure. Some insurers won't write physical damage coverage on one at all, and those that do will value it well below an equivalent clean-title vehicle.

If you're considering one, confirm you can actually insure it the way you need before buying — particularly if you're financing, since the lender will require physical damage coverage.
