An Infiniti VIN's first three characters reveal its origin: JNK, JNR, and JN1 mean Japan-built; 5N1 means Smyrna, Tennessee; 3PC means Aguascalientes, Mexico; SJK means Sunderland, UK. Decoding the 17-character VIN is free, but it does not show title brands, theft records, or accident history.

How to read each position of an Infiniti VIN

Positions 1–3, WMI: World Manufacturer Identifier. Identifies the maker and country of origin.
Positions 4–8, VDS: Vehicle Descriptor Section. Encodes body style, engine, restraint system, and model line.
Position 9, Check digit: Math-derived validator. A failed check digit can indicate a typo or a cloned VIN.
Position 10, Model year: Single character; see the table below.
Position 11, Assembly plant: Manufacturer-specific code for the factory.
Positions 12–17, Sequence: Sequential production number unique to that car.

Model-year code table (position 10)

Code	Year	Code	Year
A	1980 / 2010	S	1995 / 2025
B	1981 / 2011	T	1996 / 2026
C	1982 / 2012	V	1997 / 2027
D	1983 / 2013	W	1998 / 2028
E	1984 / 2014	X	1999 / 2029
F	1985 / 2015	Y	2000 / 2030
G	1986 / 2016	1	2001 / 2031
H	1987 / 2017	2	2002 / 2032
J	1988 / 2018	3	2003 / 2033
K	1989 / 2019	4	2004 / 2034
L	1990 / 2020	5	2005 / 2035
M	1991 / 2021	6	2006 / 2036
N	1992 / 2022	7	2007 / 2037
P	1993 / 2023	8	2008 / 2038
R	1994 / 2024	9	2009 / 2039

The position-7 rule: year codes repeat every 30 years. If position 7 is a letter the vehicle is 2010 or newer; if a digit it's 2009 or older. Letters I, O, Q, U, Z are never year codes.

Plant codes vary by model line, the decoder above returns the registered plant for your exact VIN.

Where to find the VIN on an Infiniti

On a metal plate at the base of the windshield on the driver's side (visible from outside).
On a sticker on the driver's door jamb.
Stamped on the engine block or firewall on many models.
On the title, registration, and insurance card, always confirm the paperwork matches the physical VIN. Mismatches are a serious red flag.

Infiniti title & history red flags to check before you buy

Decoding a VIN tells you how a vehicle was built. To see what happened to it, you need a full vehicle history report, which surfaces title brands, odometer readings, theft records, and more.

Q60 theft-claim leader

HLDI found the Infiniti Q60 had the highest whole-vehicle theft claim frequency of 2017–19 models (~2 claims per 1,000 insured vehicle years), check theft records before buying.

Steep depreciation → salvage-rebuild pipeline

The Infiniti QX80 is consistently flagged among the worst-depreciating vehicles in industry depreciation studies, cheap totaled QX80s/Q50s feed the rebuilt-title market.

VC-Turbo engine recall

443,899 Nissan/Infiniti vehicles (incl. 2019–2022 QX50, 2022 QX55) recalled in 2025 for engine-bearing defects that can cause total engine failure.

Takata exposure

Nissan/Infiniti vehicles are part of the ~67 million inflator, 42-million-vehicle U.S. Takata recall pool, older FX, M, and QX models should be checked for open campaigns.

Infiniti recalls: check before you buy

VC-Turbo engine bearing recall (2025, NHTSA 25V-437, 443,899 vehicles incl. QX50/QX55); Takata airbag inflator campaigns on 2000s–2010s models; various Q50 electronic steering and brake software campaigns, confirm per-VIN in the report's recall section.

Buying an Infiniti hybrid or EV?

Infiniti currently has no volume EV in the U.S.; Q50/QX60 hybrids from the 2014–2017 era carry hybrid-battery service histories worth reviewing.

What to check on a used Infiniti

A used Infiniti can be an excellent buy, but the condition you can see during a test drive is only part of the picture. Two vehicles with the same year, mileage, and asking price can have completely different histories, and the difference usually lives in the paperwork rather than under the hood.

Start with maintenance evidence. Ask for service records covering oil changes, cooling system work, brakes, tires, and any major repair, and be skeptical of a seller who offers a single recent receipt instead of a history. Inspect for mismatched paint, uneven panel gaps, replacement lights, and fresh undercoating, since all of them can mask prior collision repair. Look for rust on the frame, rocker panels, and brake lines if the vehicle spent time in a salt state.

Flood damage is the pattern buyers miss most often. Storm-damaged vehicles are frequently repaired, moved to another state, and retitled, so check for musty odors, silt under the carpet and in the spare tire well, corroded seat rails and bolts, and moisture inside light housings. A car that smells strongly of air freshener deserves a closer look.

Before money changes hands, verify the four items a visual inspection cannot answer: whether the title carries a brand such as salvage, junk, rebuilt, or flood, whether the recorded odometer readings move forward consistently over time, whether the vehicle was ever declared a total loss or reported stolen, and whether a lien is still open against it. Recall completion on the exact VIN belongs on that list too.

Infiniti VIN decoder: frequently asked questions

JNK is the World Manufacturer Identifier for Infiniti passenger cars built by Nissan in Japan, mostly at the Tochigi plant, G35/G37, M, and Q70 sedans. JNR covers Japan-built Infiniti SUVs like the FX and QX80.

Decoding is free, you'll see year, plant, engine, and trim. But free decodes don't include title history, salvage brands, theft records, or odometer readings. TitlePull's full report adds all of that, plus recalls and a Black Book valuation, for a flat $9.99.

Smyrna, Tennessee, its VIN starts with 5N1. The QX50 and QX55 are built in Aguascalientes, Mexico (3PC), and most sedans come from Japan (JNK/JN1). The first character of the VIN confirms the country instantly.

Some models, yes. HLDI data showed the Infiniti Q60 had the highest theft-claim frequency of all 2017–19 vehicles. A vehicle history report shows theft records and whether a car was ever reported stolen or recovered.

2019–2022 QX50s and 2022 QX55s with the VC-Turbo engine were part of a 443,899-vehicle recall for bearing defects that can cause engine failure. Run the VIN to see whether the recall work was needed and is still open.

Rapid depreciation, industry depreciation studies consistently rank the QX80 among the worst-depreciating vehicles in America. That's good for buyers, but it also means more total-loss declarations and rebuilt titles in the used market. Always check for title brands before buying a bargain Infiniti.

Yes, NMVTIS-backed reports show odometer readings recorded at title transfers. NHTSA estimates over 450,000 vehicles per year are sold with rolled-back odometers, so comparing recorded readings against the listing is a cheap safeguard.

A decode translates the VIN's build data (free). A history report pulls government and insurance databases: title history and brands, salvage and theft records, odometer readings, and recalls. TitlePull does both, free decode, $9.99 full report, no subscription.
