How to read a BMW M4 VIN
Here is a real 2027 BMW M4 VIN from our database, split into its parts:
VIN WBS13HK01VCY56025 — decoded free on its own report page.
| Position | Section | What it tells you |
|---|---|---|
| 1–3 | WMI | World Manufacturer Identifier — country, manufacturer and vehicle type. |
| 4–8 | VDS | Vehicle Descriptor Section — body style, engine, restraint system, series. |
| 9 | Check digit | A calculated digit that validates the whole VIN. Wrong digit = wrong VIN. |
| 10 | Model year | One character for the model year. Letters skip I, O, Q, U and Z. |
| 11 | Plant | The assembly plant that built the car. |
| 12–17 | Serial | Sequential production number of this exact vehicle. |
BMW M4 VIN prefixes, and when each one was used
Every BMW M4 we have on record, from 2015 to 2022, opens with the same three characters, WBS:
| VIN starts with | Years seen | Built in | Vehicle type | VINs on record |
|---|---|---|---|---|
| WBS | 2015–2022 | Germany | Passenger Car |
Position 11 names the plant. On the BMW M4 it is not one number either — assembly moved between 4 of them over the years:
| Plant code | Years active | VINs on record | Share |
|---|---|---|---|
| K | 2015–2017 | 28 | |
| P | 2015–2016 | 6 | |
| A | 2018–2018 | 4 | |
| C | 2021–2022 | 3 |
Counted from 46 dated BMW M4 VINs attached to NHTSA complaints, each code checked against the NHTSA manufacturer registry.

Where to find the VIN on a BMW M4
A BMW M4 VIN normally opens with WBS; the full number sits in four places, and all four must match.
| Where | How to see it | Why it matters |
|---|---|---|
| Dashboard, driver side | Through the windshield, bottom corner | Easiest to check before you touch anything |
| Driver door jamb | Open the door, sticker on the pillar | Also lists tire pressures and build date |
| Under the hood | Firewall or strut tower plate | Survives a windshield replacement |
| Title and insurance | Paper documents | Must match the car — a mismatch means fraud or a swapped panel |

What year is my M4 by its VIN?
Read position 10: a 2026 M4 carries T, a 2025 M4 carries S, a 2024 M4 carries R.
Where was my M4 built?
Position 11 names the plant. Across 46 dated BMW M4 VINs it reads K 61%, P 13%, A 9%, C 7%.
What does position 4 mean on a BMW M4 VIN?
It is part of the maker's own build code, so read it against this model, not a generic chart. On 100 BMW M4 VINs here, 3 is the most common character in position 4, on 55% of them.
What if the VIN on the dashboard doesn't match the door jamb?
On a BMW M4 check the prefix first: most genuine ones open with WBS. A plate that starts with anything else, or disagrees with the other copies of the number, needs documents checked before any money changes hands.
