Anatomy of an Audi VIN
How an Audi VIN is put together
WAU is Audi's own manufacturer code, and it is where every Audi VIN starts. Tap the blocks to see how Ingolstadt encodes model, year and plant across the remaining fourteen characters.
Characters 1 to 3
World Manufacturer Identifier
The first three characters say who built the vehicle and where. The first is the region, the second the country, the third the specific manufacturer. This block is issued centrally, so it cannot be invented.
- Code
- WAU
- Manufacturer
- Audi AG
- Region
- Europe
- Issued by
- SAE International
Characters 4 to 8
Vehicle Descriptor Section
Five characters describing the vehicle itself: model line, body style, engine, gearbox and restraint system. Each manufacturer defines its own scheme here, which is why the same characters mean different things across brands.
- Code
- ZZZ8V
- Describes
- Model, body, engine, restraints
- Defined by
- Audi AG
- Fixed length
- 5 characters
Character 9
Check digit
A single character calculated from the other sixteen. Change any one character in the VIN and this digit no longer matches, which is how a cloned or mistyped VIN gets caught before anything else is looked up.
- Value
- 4
- Calculated from
- All 16 other characters
- Possible values
- 0 to 9, or X
- Catches
- Typos, transposed characters, clones
Character 10
Model year
The model year, not the registration year. The code runs on a 30-year cycle that skips I, O, Q, U and Z so nothing can be misread as a digit. A vehicle can be built late in one model year and first registered in the next.
- Code
- K
- Model year
- 2019
- Cycle
- 30 years, letters then digits
- Not
- The registration or first-use date
Character 11
Assembly plant
The factory the vehicle was assembled in. Each manufacturer assigns its own plant codes, so this character only means something once the WMI has told you who built it.
- Code
- A
- Assembled by
- Audi AG
- Example plant
- Ingolstadt, Germany
- Assigned by
- The manufacturer
Characters 12 to 17
Production serial number
The last six characters are the vehicle's own sequence number coming off the line. This is the part that makes the VIN unique: no two vehicles from the same manufacturer, year and plant share it.
- Code
- 123456
- Length
- 6 characters
- Uniqueness
- Unique per manufacturer and year
- Also on
- V5C, chassis plate, windscreen

Warning signs
Common Warnings in an Audi VIN Decoder
If the Audi VIN decoder shows a warning, here is what it means and what to do.
Outstanding Finance on an Audi
This means money is still owed on the car. If you buy an Audi with unpaid finance, the lender could take it back. Get a full history report to confirm the finance status.
Audi Marked as Stolen
This means the car is listed as missing or stolen. Do not buy it. Check a full report to confirm the stolen status before you go any further.
Mileage Problems on an Audi
Sometimes mileage is rolled back to look lower. This can hide heavy use. A full history check compares past readings to spot mileage issues.

The basics
How an Audi VIN Is Structured
Every 17-character Audi VIN has three parts that tell you where the car was built, what it is, and its unique serial number:
WMI (World Manufacturer Identifier)
Shows country and maker. Common Audi WMIs include WAU (Audi passenger), WA1 (Audi SUV), TRU (Audi TT, Hungary) and WUA (Audi Sport).
VDS (Vehicle Descriptor Section)
Characters 4–9 describe model/body/engine and safety systems. The 9th is the check digit.
VIS (Vehicle Identifier Section)
Characters 10–17 include model year, plant code and the serial number.
Check Digit (9th)
Checks that the VIN is valid. If it fails, the VIN may be typed wrong.
Step by step
Where to Find the Audi VIN
Audi puts the VIN in several safe places. Check these common spots:
Dashboard / Windscreen
Look through the windscreen at the driver’s side lower dashboard for the VIN plate.
Driver’s Door Pillar
Open the driver’s door and check the inner B-pillar sticker.
Under the Bonnet
You may see the VIN stamped on the firewall or slam panel. It’s also on the V5C/logbook and insurance papers.

Frequently Asked Questions about Audi VINs
Where can I find the Audi VIN?
Common VIN spots include: driver’s side dashboard (seen through the windscreen), the driver’s door pillar/B-pillar sticker, under the bonnet on the slam panel or firewall, and papers like the V5C/logbook and insurance.
What do common Audi VIN prefixes mean (WMI)?
Audi WMIs often include WAU (passenger cars), WA1 (SUVs), TRU (TT, Hungary) and WUA (Audi Sport). These three characters show the maker and country.
Which character shows the model year on an Audi VIN?
The 10th character shows the model year. Letters/numbers are used; I, O and Q are skipped to avoid confusion.
Can an Audi VIN tell me the engine and trim?
The VIN shows the line, body and engine family in the VDS. Exact trim/options are best confirmed via Audi PR option codes and a detailed report.
Are Audi option codes part of the VIN?
No. Audi PR codes list factory-fitted options. They are separate from the VIN and appear on data stickers or service records.
Is the chassis number the same as the VIN on an Audi?
For modern Audis, the 17-character VIN serves as the chassis number. Older/imported vehicles may differ, but we’ll decode whatever you enter.
Can I decode a pre-1981 or imported Audi VIN?
Yes. We try to parse legacy/import formats, though detail can vary. For full checks, run a complete Audi history report.
Will the Audi VIN decoder show theft, finance and write-off status?
The free decoder gives identity and build info. Upgrade for stolen checks, outstanding finance, write-off status (Cat S/N), mileage issues and more.
Does an Audi VIN include the plant code?
Yes. The VIS (characters 10–17) includes model year, assembly plant code and the unique serial.
Why does my Audi VIN come up as invalid?
Make sure it’s exactly 17 characters with no I, O or Q. Errors in the 9th character (check digit) can also flag invalid. If it keeps failing, send us a photo of the VIN plate/sticker.
