Acura VIN Check
Shopping for a used Acura? Start with the VIN — not the seller's description. A 17-character Acura VIN encodes factory identity for models such as MDX, RDX, TLX, Integra, ZDX. DecodeAnyVin reads that code for free so you can confirm year, plant, and equipment before you drive across town for a viewing.
Acura (Honda Motor Co.) (Japan, founded 1986) assigns manufacturer-specific meaning in the Vehicle Descriptor Section (positions 4–8). 19U indicates U.S.-assembled Acura (Marysville, Ohio); JH4 indicates Japan-built models. Popular shopper checks include matching a listed MDX against the decoded line and engine.
On this page you can paste any Acura VIN into the decoder above. We check format (no I, O, or Q), verify the ISO 3779 check digit, resolve the WMI against our registry, and apply Acura-specific rules researched from NHTSA vPIC, ISO standards, and manufacturer documentation.
Acura WMI prefixes we decode
| WMI | Country | Notes |
|---|---|---|
19U | United States | U.S.-built Acura |
JH4 | Japan | Japan-built Acura |
Remember: a VIN decode shows how the vehicle left the factory. It does not show accidents, title brands, odometer history, or prior owners.
How to Read a Acura VIN
Use this Acura walkthrough when you are comparing listings, not when you only need a quick plant code.
- Copy the VIN from the windshield or door jamb — all 17 characters.
- Paste it into DecodeAnyVin on this Acura page (or the homepage).
- Confirm make, year, plant, and engine match the listing for models like MDX, RDX, TLX, Integra, ZDX.
- If anything disagrees, walk away or demand paperwork before paying a deposit.
Reading a Acura VIN by hand
Positions 1–3 (WMI). Expected prefixes include 19U (United States), JH4 (Japan). 19U indicates U.S.-assembled Acura (Marysville, Ohio); JH4 indicates Japan-built models.
Position 4 (Vehicle Line). Common mappings in our decoder: B = Civic, C = Accord, D = Prelude, E = CR-V, F = Fit / Jazz, G = Ridgeline / Pilot.
Position 5. Usually series, trim, or drivetrain detail for Acura.
Position 8 (engine / related). Examples: A = 1.3L 4-cyl, B = 1.5L 4-cyl, C = 1.6L 4-cyl, D = 1.7L 4-cyl, E = 1.8L 4-cyl.
Position 9. ISO 3779 check digit — DecodeAnyVin validates this automatically.
Position 10. Model year on the standard 30-year letter/digit cycle.
Position 11. Assembly plant. Examples: Acura plant letters.
Positions 12–17. Production serial unique to that plant line.
Acura-specific quirks to watch
- VDS codes (4–8) can change when Acura launches a new platform — charts from a different decade may mislead.
- North American market VINs follow FMVSS 565; vehicles imported privately may still use the same WMI system but different catalog data.
- Always cross-check the decoded plant and engine against the door-jamb sticker before ordering expensive parts.
Decoded attributes are informational. Confirm engine, trim, and drivetrain against the window sticker, build sheet, or a dealer before purchase, insurance, or registration decisions.

Frequently Asked Questions — Acura VIN
Where do I find the VIN on a Acura?
Dashboard, driver's door jamb, and AcuraLink app.
What does the WMI 19U mean on a Acura?
19U is a World Manufacturer Identifier used on Acura vehicles. 19U indicates U.S.-assembled Acura (Marysville, Ohio); JH4 indicates Japan-built models.
How can a Acura VIN help when buying used?
Decode the VIN before you visit the seller. Confirm model year, plant, and engine match the listing for models like the MDX or RDX. Then compare the dashboard plate with the door-jamb sticker — mismatches are a red flag.
Can I decode a Acura VIN for free on DecodeAnyVin?
Yes. Paste your 17-character Acura VIN into the form on this page. We validate the ISO 3779 check digit, resolve the WMI, read the model year and plant, and apply Acura-specific rules for positions 4–8 where available — no signup required.
Does a Acura VIN show the engine?
Often yes. On many Acura lines, position 8 (sometimes nearby VDS positions) encodes engine family. Coverage is strongest for high-volume models such as MDX and RDX; exotic or late-cycle codes may need dealer confirmation.
How do I know a Acura VIN was not altered?
Run the check digit (position 9). Example structure: 19UUB2F505FA12345. Also match the windshield VIN to the door-jamb label and reject plates that look restamped or glued. A decode cannot prove title status — only factory identity.
Is the model year on a Acura VIN always the calendar year?
No. Position 10 is the manufacturer's model year on the ISO 30-year cycle. A vehicle built in autumn may already carry next year's code. Use it as the factory model year, not the build calendar date.
Which Acura models does DecodeAnyVin support?
Any Acura with a standard 17-character VIN (typically 1981+), including MDX, RDX, TLX, Integra, ZDX. WMI and year/plant decode work broadly; detailed trim/engine depth depends on documented VDS rules for that platform.
