How to read a Maserati Quattroporte VIN
Here is a real 2022 Maserati Quattroporte VIN from our database, split into its parts:
VIN ZAM56YRMXN1388375 — decoded free on its own report page.
| Position | Section | What it tells you |
|---|---|---|

| 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. |

| 12–17 | Serial | Sequential production number of this exact vehicle. |
Maserati Quattroporte VIN prefixes, and when each one was used
Every Maserati Quattroporte we have on record, from 2005 to 2023, opens with the same three characters, ZAM:
| VIN starts with | Years seen | Built in | Vehicle type | VINs on record |
|---|---|---|---|---|
| ZAM | 2005–2023 | Italy | Passenger Car |
Position 11 names the plant. On the Maserati Quattroporte it is not one number either — assembly moved between 2 of them over the years:
| Plant code | Years active | VINs on record | Share |
|---|---|---|---|
| 0 | 2005–2012 | 26 | |
| 1 | 2014–2021 | 18 |
Counted from 45 dated Maserati Quattroporte VINs attached to NHTSA complaints, each code checked against the NHTSA manufacturer registry.

Where to find the VIN on a Maserati Quattroporte
A Maserati Quattroporte VIN normally opens with ZAM; 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 Quattroporte by its VIN?

Where was my Quattroporte built?
Position 11 names the plant. Across 45 dated Maserati Quattroporte VINs it reads 0 58%, 1 40%.
What does position 4 mean on a Maserati Quattroporte VIN?
It is part of the maker's own build code, so read it against this model, not a generic chart. On 27 Maserati Quattroporte VINs here, 5 is the most common character in position 4, on 70% of them.
What if the VIN on the dashboard doesn't match the door jamb?
On a Maserati Quattroporte check the prefix first: most genuine ones open with ZAM. A plate that starts with anything else, or disagrees with the other copies of the number, needs documents checked before any money changes hands.
