A Infiniti VIN is 17 characters. Positions 1–3 say who built it and where, 4–8 describe the body and engine, 9 is a check digit, 10 is the model year, 11 is the plant, and 12–17 are the serial number. On a Infiniti those first three characters are almost always JN1, 5N1, JN8 — 78% of the 364 VINs decoded here start with one of them.
How to read a Infiniti VIN
Here is a real 2027 Infiniti VIN from our database, split into its parts:
VIN 5N1AC0FX4VC605950 — 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. |
Which Infiniti is it? Read the first three characters
Characters 1–3 are the World Manufacturer Identifier, and Infiniti runs 8 of them across 4 countries, so on a Infiniti the prefix alone tells you which line the car came off and what body it was built as. Counted across 364 Infiniti VINs decoded here:
| WMI | Built in | Vehicle type | Models under this code | VINs on file |
|---|---|---|---|---|
| JN1 | Japan | — | EX35, G25, G37, M35, M37 + 6 more | |
| 5N1 | United States | — | JX35, QX60, QX65 | |
| JN8 | Japan | — | FX35, FX37, QX56, QX70, QX80 | |
| JNK | Japan | — | EX35, G35, G37, I35, J30 + 3 more | |
| 3PC | Mexico | — | QX50, QX55 | |
| JNR | Japan | — | FX35, FX45, QX4 | |
| SJK | United Kingdom | — | QX30 | |
| 5N3 | United States | — | QX56 |
Country and vehicle type come from the NHTSA manufacturer registry; the model column is counted from Infiniti VINs decoded on ForCar, so it reflects what people actually own, not the full production catalogue.
Model-year codes for Infiniti
Position 10 carries the model year, skipping I, O, Q, U and Z. The alphabet comes round every 30 years, which for Infiniti has already happened — 1997 and 2027 share the character V. All 48 model years of Infiniti, 1980 to 2027, with the character each one carries:
| Model year | VIN character (position 10) | Same character as |
|---|---|---|
| 2027 | V | 1997 |
| 2026 | T | 1996 |
| 2025 | S | 1995 |
| 2024 | R | 1994 |
| 2023 | P | 1993 |
| 2022 | N | 1992 |
| 2021 | M | 1991 |
| 2020 | L | 1990 |
| 2019 | K | 1989 |
| 2018 | J | 1988 |
| 2017 | H | 1987 |
| 2016 | G | 1986 |
| 2015 | F | 1985 |
| 2014 | E | 1984 |
| 2013 | D | 1983 |
| 2012 | C | 1982 |
| 2011 | B | 1981 |
| 2010 | A | 1980 |
| 2009 | 9 | — |
| 2008 | 8 | — |
| 2007 | 7 | — |
| 2006 | 6 | — |
| 2005 | 5 | — |
| 2004 | 4 | — |
| 2003 | 3 | — |
| 2002 | 2 | — |
| 2001 | 1 | — |
| 2000 | Y | — |
| 1999 | X | — |
| 1998 | W | — |
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 Infiniti VINs
Positions 4 through 8 describe the build, and manufacturers assign them themselves — the same letter means different things on different marques. Across 364 VINs Infiniti uses 18 different characters in these three slots alone — the ones below, ordered by how much of the Infiniti fleet each covers:
| Position | Characters seen on real VINs | Variety |
|---|---|---|
| 4 — body | A (30%) · C (24%) · B (16%) · D (15%) · E (12%) · F (4%) | 6 distinct |
| 5 — series | V (44%) · L (23%) · Z (12%) · J (8%) · S (5%) · Y (4%) | 6 distinct |
| 8 — engine | R (24%) · E (16%) · P (13%) · M (7%) · S (7%) · W (5%) | 6 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.
What a decoded Infiniti VIN gets you
Reading the characters is the easy part — the reason to decode a VIN is what sits behind it. For Infiniti that is 4,627 owner complaints and every recall campaign NHTSA has on record, keyed to the same VIN you just read:
| Data | For this brand | Source |
|---|---|---|
| Models covered | 33 Infiniti models | ForCar catalog |
| Recall campaigns | 414 across the brand | NHTSA |
| Owner complaints | 4,627 filed by Infiniti owners | NHTSA |
| Model years covered | 37 years (1990–2026) | ForCar catalog |
| VINs already decoded | 364 Infiniti VINs on file | ForCar |
Where to find the VIN on a Infiniti
Before hunting for the plate, know what you are looking for: a genuine Infiniti VIN opens with one of JN1, 5N1, JN8, JNK, 3PC, JNR. Four places on a Infiniti carry that number, and all four must read the same — a mismatch on this brand 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 |
Decode a VIN by Infiniti model
Codes in positions 4–8 are assigned per model, not per brand, and Infiniti has 33 of them in our catalogue. 6 of the prefixes above cover more than one model, so the table on this page narrows it down but does not finish the job. Open the Infiniti you own for the plants, year codes and build characters that apply to it alone.

Frequently asked questions
Is this Infiniti VIN decoder free?
Yes — decoding a Infiniti VIN costs nothing and needs no account. Beyond the year, plant and build characters you also get what NHTSA holds on the Infiniti — 414 recall campaigns and 4,627 owner complaints — at no charge.
What do the first three characters of a Infiniti VIN mean?
That block is the World Manufacturer Identifier, and on a Infiniti it resolves to one of 8 codes — each tying the car to a plant country and a body type before you read any further. The ones that turn up most on Infiniti VINs here are JN1 (Japan — EX35, G25, G37); 5N1 (United States — JX35, QX60, QX65); JN8 (Japan — FX35, FX37, QX56). The full list, with the models built under each, is in the table above.
Where was my Infiniti built?
Character 11 names the plant, but the country is already set by characters 1–3. Of the 364 Infiniti VINs decoded on ForCar, assembly splits as Japan 71%, United States 24%, Mexico 4%, United Kingdom 2%. Match your first three characters to the table above to see which one is yours.
How many characters is a Infiniti VIN?
Seventeen, on every Infiniti built from 1981 onwards, when the 17-character format became mandatory in the US. Our oldest Infiniti on file is a 1980, from before that rule — those carry a shorter code that Infiniti laid out its own way.
Why do two Infiniti model years share the same VIN character?
Position 10 cycles through the alphabet every 30 years, skipping I, O, Q, U and Z. For Infiniti that is not theoretical: a 1997 and a 2027 both carry V in position 10, and this brand was built in both years. The check digit and serial range separate them.
Can a Infiniti VIN tell me if the car was in an accident?
Not from the characters themselves — they describe how the Infiniti 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 4,627 complaints Infiniti 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 Infiniti?
No, and that is the usual mistake — positions 4–8 are assigned per model, not per brand. A letter that means one body on a Infiniti means something else entirely on another marque. On Infiniti VINs the character that dominates position 4 is A — 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 Infiniti check the prefix first: if the first three characters are not one of the 8 codes listed above, the plate did not come from this brand at all. Beyond that, mismatched plates mean either a replaced panel or a tampered identity — ask for documents and verify before any money changes hands.
