Free Audi VIN Decoder
Decode any Audi VIN into its factory build sheet — model year, trim, engine, transmission, drivetrain and assembly plant — from official NHTSA vPIC data.
Enter any Audi VIN below. A Audi VIN starts with W (built in Germany), under the World Manufacturer Identifier system defined in 49 CFR 565. The decoder returns the exact model year, trim, engine, drivetrain and assembly plant, plus open NHTSA recalls and crash-test ratings for the vehicle — free, unlimited, no registration.
What each VIN position means on a Audi
Every vehicle sold in the United States since 1981 carries a 17-character VIN under federal standard 49 CFR 565 (international standard ISO 3779). The letters I, O and Q are never used, to avoid confusion with the digits 1 and 0.
| Positions 1–3 | World Manufacturer Identifier. Position 1 identifies the country of assembly. On a Audi it is W (built in Germany). Positions 2–3 identify the manufacturer and vehicle type — 5 WMI codes are registered to Audi (full table below). |
|---|---|
| Positions 4–8 | Vehicle Descriptor Section. Model, body style, engine, restraint system and transmission, as coded by the manufacturer. |
| Position 9 | Check digit. A number (0–9) or X, computed from the other 16 characters with a weighted modulus-11 formula. It detects typos and tampering — validate one here. |
| Position 10 | Model year code. A repeating 30-year cycle (Y = 2000, 1 = 2001, …). |
| Position 11 | Assembly plant. Manufacturer-assigned plant code. |
| Positions 12–17 | Serial number. Unique production sequence of the vehicle. |
Position meanings 4–8 are manufacturer-specific. Decoding the VIN returns the exact decoded values — see our data sources.
