How to Find Your VIN Number

Every vehicle sold in the US since 1981 has a unique 17-character Vehicle Identification Number. Here's where to find it, and how to read it once you do.

1. Driver's side dashboard

Stand outside the car and look through the windshield at the corner of the dashboard on the driver's side. The VIN is stamped on a small metal or plastic plate. This is the fastest place to check, and the one law enforcement and inspectors use.

2. Driver's side door jamb

Open the driver's door and look at the door frame (not the door itself) — there's usually a sticker with the VIN, along with tire pressure and paint code information.

3. Vehicle title and registration

The VIN is printed on your title, registration card, and any loan or lease paperwork. This is the version to trust if a physical plate looks damaged or hard to read.

4. Insurance card or policy documents

Your insurance company records the VIN on your policy. Check your insurance card or declarations page.

5. Engine block

Many manufacturers stamp a partial or full VIN directly onto the engine block. Location varies a lot by make and model — check your owner's manual for the exact spot.

6. Frame, near the front wheel

On some vehicles, especially older ones and trucks, the VIN is stamped into the frame rail, often visible by looking down into the wheel well on the driver's side.

How to read a VIN once you have it

A VIN is always 17 characters — letters and numbers, no letters I, O, or Q (they're excluded to avoid confusion with 1 and 0):

Positions 1–3 — World Manufacturer Identifier (WMI): country and manufacturer
Positions 4–8 — Vehicle Descriptor Section: model, body style, engine, restraint system
Position 9 — Check digit, used to detect transcription errors
Position 10 — Model year
Position 11 — Assembly plant
Positions 12–17 — Sequential production/serial number, unique to that vehicle

You don't need to decode this by hand — enter the VIN into our free VIN decoder and it will pull the manufacturer's actual reported data for every one of these fields.
