How to read a Audi Q4 VIN
Here is a real 2025 Audi Q4 VIN from our database, split into its parts:
VIN WA1LUBFZ5SP056653 — 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. |
Where Audi Q4 VINs say the car was built
The first three characters are the World Manufacturer Identifier. Across 26 Audi Q4 VINs we have on file, these are the codes that actually show up — and the plants behind them:
| WMI | Built in | Vehicle type | VINs on file | Share |
|---|---|---|---|---|
| WA1 | Germany | Multipurpose Passenger Vehicle (MPV) | 26 |
Country and vehicle type come from the NHTSA manufacturer registry. Share is measured across VINs decoded on ForCar, not production volume.
Model-year codes for the Audi Q4
Position 10 carries the model year, skipping I, O, Q, U and Z. The alphabet comes round every 30 years, which the Audi Q4 has not yet outlived: its 5 years still map one-to-one. All 5 model years of the Audi Q4, 2022 to 2026, with the character each one carries:

|---|---|---|
| 2026 | T | — |

Where to find the VIN on a Audi Q4
A Audi Q4 VIN normally opens with WA1; 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 |
