Infiniti VIN Decoder & Check
Decode any Infiniti VIN free, then read the full vehicle history before you buy.
Buying a used Infiniti?
Infiniti launched in 1989, the same year as Lexus, as Nissan's luxury division. The G35 and G37 sport sedans gave the brand its enthusiast credibility in the 2000s; today the lineup centers on the Q50 sedan and the QX60 and QX80 SUVs.
Infinitis depreciate faster than their German and Japanese rivals, which makes them some of the best raw value on the used luxury market and also some of the most scrutinized. Steep depreciation attracts rebuilders, since a lightly damaged QX60 costs little at auction and resells near clean-market money. The gap between those two cars lives entirely in the history report.
Infiniti history: what to verify before you buy
Every brand has its own used-market patterns. These are the ones worth checking on an Infiniti, and where the report answers each one.
CVT service history on QX60s
The continuously variable transmission in 2014 to 2016 QX60s drew enough complaints that Nissan extended coverage on related models. The odometer chronology alongside the factory maintenance schedule shows whether a given car's miles and service expectations line up.
Timing chain wear on older G sedans
Mid-2000s G35s and related V6 models had documented timing chain tensioner issues. On cars this age, a coherent mileage history with no gaps is the best available signal of a drivetrain that was maintained rather than endured.
Rebuilt luxury at retail prices
Fast depreciation makes lightly crashed Infinitis profitable to rebuild and resell. Title brands, reported damage, and salvage-auction photos in the report reveal the rebuild the fresh paint conceals.
Off-lease reconditioning
Most used Infinitis are lease returns prepared for certified lots. The report's damage and auction records show what happened during the lease years, before the detailer got involved.
How to decode an Infiniti VIN
Every Infiniti built since 1981 carries a 17-character VIN, and each position means something specific. Here is how to read one yourself, or paste it above and let the decoder do it in seconds.
Example VIN for illustration. Positions 1 to 3 identify the manufacturer, 4-8 describe the vehicle, 9 is the check digit, 10 is the model year, 11 is the assembly plant, and 12-17 are the serial number.
Positions 1-3: where your Infiniti was built
The first three characters are the World Manufacturer Identifier, assigned to a specific company, country, and vehicle type. This is the fastest answer to the question of which factory built the car.
| WMI code | Built in | Typically used on |
|---|---|---|
| JNK | Japan | Japan-built sedans such as the Q50 |
| JN1 | Japan | Japan-built cars, including G-series sedans |
| JN8 | Japan | Japan-built SUVs |
| 5N3 | Canton, Mississippi | US-built QX56 and QX80 SUVs |
Common Infiniti manufacturer codes. Codes vary by model, plant, and era, so a code outside this table is not by itself a red flag. The free decoder above resolves any Infiniti VIN to its exact factory record.
Positions 4-8: what the vehicle is
Infiniti VINs carry the model line, engine, body, and restraint data in positions 4 through 8, separating rear-drive and all-wheel-drive Q50s that look identical from the curb.
Position 9: the check digit
A number computed from all the other characters using a federal formula. If someone alters a VIN by hand, the math stops working. It is the first thing our decoder verifies, and a failed check digit on a listing is a walk-away signal.
Position 10: the model year
One character encodes the model year. Letters and digits alternate in a 30-year cycle, so the same code serves two eras:
Year codes repeat every 30 years. Position 7 settles the cycle: on 17-character VINs, a letter there means the vehicle is from 2010 or later, a digit means 1981-2009.
Positions 11-17: plant and serial number
Position 11 names the assembly plant within the factory network, and the final six characters are the serial number, unique to this one Infiniti. Together with the rest of the VIN, they make the identity impossible to share honestly, which is exactly why cloned VINs are worth checking for.
