Understanding VIN Numbers

The 17 positions explained

Positions 1-3: WMI (World Manufacturer Identifier)

Country and manufacturer.

Position 1: Country of manufacture.

  • 1, 4, 5: USA
  • 2: Canada
  • 3: Mexico
  • J: Japan
  • K: South Korea
  • L: China
  • W: Germany
  • S: UK
  • V: Spain or France

Position 2: Manufacturer. Position 3: Vehicle type or division.

Examples:

  • 1FT: Ford US Truck
  • 2HG: Honda Canada
  • JT2: Toyota Japan
  • WBA: BMW Germany

Positions 4-8: VDS (Vehicle Descriptor)

Encodes model, body style, restraint system, engine.

Positions 4-7: Model specifics (varies by manufacturer). Position 8: Engine code.

Example for 2018 Toyota Camry LE 2.5L:

  • Position 8: "F" indicates A25A-FKS 2.5L 4-cylinder.

Position 9: Check digit

Calculated from all other positions. Validates VIN authenticity. Any other character means the VIN was altered or copied wrong.

Position 10: Model year

Letters and numbers per year:

  • B: 1981/2011
  • C: 1982/2012
  • D: 1983/2013
  • E: 1984/2014
  • F: 1985/2015
  • G: 1986/2016
  • H: 1987/2017
  • J: 1988/2018
  • K: 1989/2019
  • L: 1990/2020
  • M: 1991/2021
  • N: 1992/2022
  • P: 1993/2023
  • R: 1994/2024
  • ...

The cycle repeats every 30 years. For 2015 Honda Civic: position 10 should be "F". For 2018 Camry: "J".

Position 11: Plant code

Manufacturing facility. Often useful for identifying region of build and for warranty work.

Positions 12-17: Serial number

Sequential production number. The 6-digit serial.

How to read a sample VIN

2015 Honda Civic example: 19XFB2F86FE000123

  • 1-3 (19X): Honda US (Honda of America, Marysville Ohio).
  • 4-8 (FB2F8): Civic LX sedan, 1.8L R18 engine.
  • 9 (6): check digit.
  • 10 (F): 2015 model year.
  • 11 (E): East Liberty plant.
  • 12-17 (000123): serial number.

Where to find your VIN

  • Dashboard at base of windshield (visible from outside).
  • Driver side door jamb sticker.
  • Vehicle registration and title.
  • Insurance card.
  • Service records.

If the dashboard VIN doesn't match the door jamb VIN, the vehicle may be stolen and re-VINned — major red flag.

Free VIN decoders

When VIN decoding matters

Buying a used car

Verify the listing matches the VIN's actual specs. A "2015 LX" that decodes as "LE base" may be misrepresented.

Ordering parts

Some platforms require exact engine code, trim, plant for correct fit. The VIN tells you all of that.

Checking recalls

The NHTSA database returns active recalls by VIN. Critical for used-car buyers and current owners.

Insurance and registration

VIN is the unique identifier across all paperwork.

VIN fraud signs

  • Dashboard VIN differs from door jamb.
  • Door jamb sticker tampered with.
  • VIN plate riveted unevenly (factory rivets are uniform).
  • Letters O, I, Q used (these are excluded from VINs to prevent confusion with 0, 1, etc.).

If you see any of these on a vehicle you're considering, walk away.

FAQ

What does my VIN tell you?
Country and manufacturer of build, model, body style, engine code, model year, manufacturing plant, and unique serial number. The NHTSA VIN database decodes all of this for free at vpic.nhtsa.dot.gov.
How do I find my VIN?
Easiest: stand outside the vehicle and look at the base of the windshield on the driver side. The VIN is on a small plate visible through the glass. Also on the door jamb sticker, registration, title, and insurance card.
What's the check digit in a VIN?
Position 9 is a check digit calculated mathematically from the other 16 characters. It validates the VIN is genuine. If position 9 doesn't match the expected calculation, the VIN was altered or copied wrong.
Can two cars have the same VIN?
Never legally. VINs are unique globally. Identical VINs on two vehicles indicate fraud (cloning) — typically from a stolen vehicle being re-VINned to match a legitimate one. NHTSA database catches most cases.
