When you order a genuine part, the most useful thing you can have to hand is your car's VIN. Those 17 characters carry more information than a registration number, and they are the quickest way to make sure the part you buy is the one your car was built with. This guide explains where to find your VIN, what the main sections mean, and why we sometimes ask for it before confirming fitment.
What is a VIN?
VIN stands for Vehicle Identification Number. Every car built since 1981 has a unique 17-character VIN, made up of letters and numbers. The letters I, O and Q are never used, so they can't be confused with 1 and 0.
A registration number can move from car to car with a private plate, and it tells you little about how the car was built. The VIN stays with the car for life and links back to the factory build record.
Where to find your VIN
There are several places to look, and it is worth checking that they agree:
- Your V5C logbook lists the VIN in the vehicle details section.
- The base of the windscreen, usually on the passenger side, where a small plate can be read from outside the car.
- The door pillar or a sticker in the door shut on many models.
- Stamped into the body, often under the bonnet or under a flap in the carpet by the front seat.
If you send a VIN to us, a clear photo of the windscreen plate or the V5C line is ideal. Please cover your name and address on the logbook first, as we only need the VIN.
Breaking down the 17 characters
A VIN is split into three main sections. The exact use of each character varies between manufacturers, but the overall layout is the same.
Characters 1 to 3: World Manufacturer Identifier
The first three characters show who made the car and, roughly, where. A few common examples:
- WVW – Volkswagen passenger cars (VW SUVs such as the Tiguan usually start WVG)
- WAU – Audi cars (Audi SUVs usually start WA1)
- VSS – SEAT
- TMB – Skoda
- KMH – Hyundai cars built in Korea (TMA for Hyundais built in the Czech Republic)
- KNA / KNE – Kia built in Korea (U5Y / U6Y for Kias built in Slovakia)
- WF0 – Ford built in Germany
- SB1 – Toyota built in the UK
The first character also hints at the country of build. W is Germany, K is South Korea, J is Japan, S is the UK, TM is the Czech Republic, VF is France and VS is Spain. A Hyundai or Kia built in Europe, for example, will start differently from one built in Korea.
Characters 4 to 9: Vehicle Descriptor Section
This section describes the car itself. Depending on the make, it can identify the model, body style, engine or restraint system. On many Volkswagen Group cars, characters 7 and 8 show the model platform code, which is very useful when you are matching body panels, trim and lights. The ninth character is often a check digit used to spot mistyped VINs, although European cars don't always use it.
Characters 10 to 17: Vehicle Identifier Section
Character 10 usually shows the model year. For recent cars, L is 2020, M is 2021, N is 2022, P is 2023, R is 2024, S is 2025 and T is 2026. Model year doesn't always match the registration date, as a car built late in the year can carry the following year's code. Character 11 is normally the assembly plant, and the last six characters are the car's own serial number.
Why the VIN matters when buying parts
Manufacturers change parts during a model's life far more often than most people realise. A facelift can bring new headlights, bumpers and grilles. A mid-year update can switch a sensor, a wiring connector or a brake size, and two cars that look identical on the drive can need different parts.
The factory parts systems used by dealers work from the VIN. Entering it filters the parts catalogue down to what was fitted to that exact car, including engine and gearbox codes, trim level and options. That is how a dealer or parts specialist can confirm a part number with confidence, rather than guessing from the model name and year.
Once you have the right part number, the rest is simple. Our guide on how to read a genuine VW, Audi, SEAT & Skoda part number explains what each section of the number means, including the suffix letters that show revisions and colours.
VIN tips for common makes
- VW, Audi, SEAT and Skoda: many parts depend on option codes (PR codes) recorded against the VIN, such as headlight type or brake size. The VIN is the most reliable way to check these. Browse our Volkswagen, Audi, SEAT and Skoda parts.
- Hyundai and Kia: parts often change between European-built and Korean-built cars of the same model, so the first three characters matter. See our Hyundai and Kia parts.
- Ford and Toyota: the VIN helps separate engine variants and production changes within a single model range. Take a look at our Ford and Toyota parts.
Is it safe to share your VIN?
Yes, for parts enquiries. A VIN doesn't reveal your name or address, and it is already visible through your windscreen. It is a normal part of buying parts and is the same number a main dealer would ask for. Just avoid sending photos of other personal documents alongside it.
How we can help
Every part we sell is new and genuine, and each listing starts with the manufacturer's part number. If you are not sure a part fits, send us your VIN with your question and we'll do our best to confirm the part number before you order. A few minutes checking now can save a return and a wasted weekend later.
