How to read a Acura RLX VIN
Here is a real 2020 Acura RLX VIN from our database, split into its parts:
VIN JH4KC2F94LC000764 — 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 Acura RLX VINs say the car was built
The first three characters are the World Manufacturer Identifier. Across 11 Acura RLX 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 |
|---|---|---|---|---|
| JH4 | Japan | — | 11 |
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 Acura RLX
Position 10 carries the model year, skipping I, O, Q, U and Z. The alphabet comes round every 30 years, which the Acura RLX has not yet outlived: its 13 years still map one-to-one. All 13 model years of the Acura RLX, 2014 to 2026, with the character each one carries:

Where to find the VIN on a Acura RLX
A Acura RLX VIN normally opens with JH4; 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 |
