How to read a Buick Park Avenue VIN
Here is a real 2002 Buick Park Avenue VIN from our database, split into its parts:
VIN 1G4CW54K824243454 — 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 Buick Park Avenue VINs say the car was built
The first three characters are the World Manufacturer Identifier. Across 6 Buick Park Avenue 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 |
|---|---|---|---|---|
| 1G4 | United States | — | 6 |
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 Buick Park Avenue
Position 10 carries the model year, skipping I, O, Q, U and Z. The alphabet comes round every 30 years, which the Buick Park Avenue has not yet outlived — its 15 years still map one-to-one. All 15 model years of the Buick Park Avenue, 1991 to 2005, with the character each one carries:
| Model year | VIN character (position 10) | Same character as |
|---|---|---|
| 2005 | 5 | — |
| 2004 | 4 | — |
| 2003 | 3 | — |
| 2002 | 2 | — |
| 2001 | 1 | — |
| 2000 | Y | — |
| 1999 | X | — |
| 1998 | W | — |
| 1997 | V | — |
| 1996 | T | — |
| 1995 | S | — |
| 1994 | R | — |
| 1993 | P | — |
| 1992 | N | — |
| 1991 | M | — |
When two years share a character, the check digit and serial range tell them apart — that is what the decoder does automatically.
Body and engine characters we see on Buick Park Avenue VINs
Positions 4 through 8 describe the build, and manufacturers assign them themselves — the same letter means different things on different marques. Across 6 VINs the Buick Park Avenue uses 3 different characters in these three slots alone — the ones below, ordered by how much of the Buick fleet each covers:
| Position | Characters seen on real VINs | Variety |
|---|---|---|
| 4 — body | C (100%) | 1 distinct |
| 5 — series | W (100%) | 1 distinct |
| 8 — engine | K (100%) | 1 distinct |
A character that dominates the column usually marks the body style the model was mostly sold in; a spread across several means multiple bodies or engines shared the same platform.

Where to find the VIN on a Buick Park Avenue
A Buick Park Avenue VIN normally opens with 1G4. Four places on the car carry the full number, and all four must agree — on a Buick Park Avenue, a plate that disagrees is where fraud shows itself first.
| 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 tyre 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 |

Frequently asked questions
Is this Buick Park Avenue VIN decoder free?
Yes — decoding a Buick Park Avenue VIN costs nothing and needs no account. Beyond the year, plant and build characters you also get what NHTSA holds on the Buick Park Avenue — 22 recall campaigns and 856 owner complaints — at no charge.
How many characters is a Buick Park Avenue VIN?
Seventeen, on every Buick Park Avenue built from 1981 onwards, when the 17-character format became mandatory in the US. The oldest Buick Park Avenue VIN on file here is a 1999, so everything in our Buick data already uses the modern layout.
Why do two Buick Park Avenue model years share the same VIN character?
Position 10 cycles through the alphabet every 30 years, skipping I, O, Q, U and Z. A 1995 and a 2025 car can carry the same letter. The check digit and serial range separate them.
Can a Buick Park Avenue VIN tell me if the car was in an accident?
Not from the characters themselves — they describe how the Buick Park Avenue left the factory, not what happened to it afterwards. Crash and title records sit in separate databases keyed to the same number. What is public are the 856 complaints Buick Park Avenue owners filed with NHTSA, and those we do show. Run the number through our VIN check to see what is on the record for it.
Do the body and engine characters mean the same thing on every Buick?
No, and that is the usual mistake — positions 4–8 are assigned per model, not per brand. A letter that means one body on the Buick Park Avenue can mean a different one on another Buick, and something else again on another marque. On Buick Park Avenue VINs the character that dominates position 4 is C — read it against the table above, not against a generic chart.
What if the VIN on the dashboard doesn't match the door jamb?
Treat it as a red flag on any car, and on a Buick Park Avenue check the prefix first: a genuine one opens with 1G4, and a plate that starts otherwise did not come off this car. Beyond that, mismatched plates mean either a replaced panel or a tampered identity — ask for documents and verify before any money changes hands.
