Acura VIN Decoder: What Every Digit Means

Acura has built its reputation on Honda's engineering foundation — reliable platforms, refined powertrains, and a loyal used-car following. That reputation also creates a specific blind spot for buyers: Acura vehicles hold value well enough that sellers rarely feel pressure to disclose problems, and a clean exterior on a well-depreciated MDX or TLX can hide significant accident history, open recall exposure, or an undisclosed title event. The used luxury segment runs between $18,000 and $55,000 for most Acura models, making the cost of a missed history check far higher than the cost of running one.

This guide breaks down every digit of an Acura VIN, explains what each position reveals about the vehicle, and shows you exactly how to run a complete history report before you commit to a purchase. For an instant free result, see the free tools comparison below.

Where to Find the VIN on an Acura

Acura follows Honda's consistent VIN placement conventions across all models:

• Dashboard (primary location): Visible through the windshield on the driver's side — a metal plate at the base of the windshield where it meets the dashboard. This is the first place to look on any Acura.
• Driver's door jamb: A white sticker affixed inside the door frame near the latch. This label also shows tire placard data, GVWR (on SUVs), and the manufacture date.
• Engine block or firewall: The VIN is stamped on the engine block or the firewall on the driver's side — useful when verifying that the engine has not been swapped, which is rare on Acuras but worth confirming on high-performance models like the TLX Type S.
• All models: Also printed on the title, registration certificate, and insurance card. Always compare the document VIN against the physical VIN before purchasing.

VIN tampering is far less common on Acura than on high-theft truck models, but VIN cloning — where a stolen vehicle is fitted with plates from a clean-titled counterpart — has been documented on popular MDX and RDX trims. Always verify that the dashboard plate and door jamb sticker match exactly before proceeding.

Acura VIN Decoder: Digit by Digit

Here is what each position in an Acura VIN tells you:

Position 1: Country of manufacture

A "1" in position 1 means the vehicle was assembled in the United States — the overwhelming majority of Acuras sold since the mid-1990s. "2" indicates Canada, which applies to certain MDX models built at Honda's Alliston, Ontario plant to supplement US production capacity. "J" indicates Japan, which applies to a small number of early Acura models (primarily pre-2000) and the NSX (which moved to the Performance Manufacturing Center in Ohio for its second generation). For most used Acura buyers, the VIN will begin with "1."

Positions 2–3: Manufacturer and vehicle type

The WMI works as a three-character set. 19U is the most common Acura WMI — it identifies American Honda Motor Co. building a passenger car in the United States. This covers the ILX, TLX, and Integra sedans.

5J8 identifies American Honda Motor Co. building a multipurpose vehicle (SUV) in the United States — this is the WMI for the current MDX and RDX. JH4 identifies Honda Motor Co. Japan building a passenger car — this appears on older Acura models imported before US manufacturing was established, and is now rare in the used market. 2HN identifies Canadian-built Acura MPVs, used on MDX models from Alliston, Ontario through 2013.

If a vehicle is presented as an Acura but the first three characters don't match one of these known WMIs, the VIN requires verification before proceeding.

Position 8: Engine code

On most Acura models, position 8 within the VDS section helps identify the engine or powertrain variant. On current Acura models, this matters particularly for buyers evaluating the turbocharged 2.0L VTEC Turbo found in the Integra and TLX base, the 3.0L turbocharged V6 in the TLX Type S, and the 3.5L naturally aspirated V6 that powers the MDX and RDX (non-Type S). Hybrid powertrain variants — the MDX Sport Hybrid — also carry distinct engine codes. Always cross-reference position 8 with the model year from position 10, as the same position 8 character can mean different engines across different years.

Position 10: Model year

VIN year codes skip certain letters — I, O, Q, U, and Z — to avoid transcription confusion, which is why the sequence jumps from S (2025) to T (2026) to V (2027). Acura's model year position matters for buyers more than many brands because Acura has gone through significant platform changes in recent years — the fourth-generation MDX (2022+), the redesigned TLX (2021+), and the revived Integra (2023+) are fundamentally different vehicles from their predecessors in terms of platform, engine, and recall exposure. A 2019 TLX and a 2022 TLX share a name but little else. Always verify position 10 before evaluating which generation you're actually looking at.

Position 9: The check digit

Position 9 is a mathematically derived check digit calculated from the other 16 characters using the ISO 3779 algorithm. A VIN that fails this check is fabricated or tampered — it should not be purchased and should be reported. Acura vehicles are not among the highest-theft targets, but the MDX in particular has appeared in theft statistics in urban markets, making VIN integrity worth confirming on any used Acura SUV purchased through private channels.

What an Acura VIN Check Can Reveal

Acura's positioning as a near-luxury brand means buyers typically spend more than they would on a comparable mainstream vehicle — which raises the stakes for missing something in the history. A full VIN report surfaces what the seller's description doesn't include:

• Accident history — Acura repair costs are meaningfully higher than comparable non-luxury vehicles. An MDX structural repair or airbag replacement can run $6,000–$15,000. Insurance claims reported to NMVTIS will appear in a paid VIN report even when the seller claims "no accidents."
• Title status — A rebuilt or salvage title on an Acura typically reflects serious collision damage. Some flood-affected Acura MDX and RDX vehicles entered secondary markets after major hurricane events; a title brand will appear in the NMVTIS database regardless of how many times the vehicle changes hands.
• Open recalls — Acura has had numerous VIN-specific recall campaigns across recent model years. A VIN report will surface which campaigns have been completed and which remain open — including safety-critical software and mechanical recalls.
• Odometer records — Acuras are popular corporate and executive fleet vehicles. A car that reads 42,000 miles but has had three owners and multiple title transfers in four years deserves closer scrutiny on odometer history.
• Ownership history — Multiple short-term owners on a recent-model Acura can signal an undisclosed problem the seller discovered after purchase.
• Lien records — Ownership history as reported through NMVTIS-approved providers.

Acura VIN Check by Model: What to Look For

Acura MDX

The MDX uses 5J8 as its WMI (US-built at East Liberty, Ohio). It is America's all-time best-selling three-row luxury SUV, which means high used-car volume and a wide range of condition. The fourth generation (2022+) is a substantially redesigned vehicle built on an all-new platform — don't conflate its reliability profile with older generations. On 2014–2020 MDX models, look specifically for the fuel pump recall history and any reported transmission irregularities on Sport Hybrid variants. Confirm the SH-AWD system functions correctly — repairs can be expensive when deferred.

Acura RDX

The RDX uses 5J8 as its WMI (US-built at East Liberty, Ohio). The third generation (2019+) introduced the turbocharged 2.0L engine and a significant redesign. Pre-2019 RDX models used a naturally aspirated 3.5L V6 and carry a different ownership profile. On 2019–2022 RDX models, verify the VIN against any open airbag-related recall history and confirm the AcuraWatch suite (collision mitigation, lane keeping) is functioning — these systems are expensive to repair if they've been damaged in a prior accident that went undisclosed.

Acura TLX

The TLX uses 19U as its WMI (US-built at Marysville, Ohio). The 2021 redesign was a complete ground-up new generation — the current TLX shares nothing with the 2015–2020 first-generation model. On 2021–2025 TLX and TLX Type S models, check whether any open FI-ECU software recall has been completed — the 2025 recall (25V031) covered stall-risk in Type S variants and should be resolved before purchase. On older (2015–2020) TLX models, review transmission service history and confirm no unresolved airbag-related campaigns remain open.

Acura Integra

The revived Integra (2023+) uses 19U and is built at Marysville alongside the TLX. As a newer model it has a shorter used-car history, but early ownership transfers on a 2023 or 2024 Integra are worth scrutinizing. Verify the VIN against the NHTSA recall database — the Integra shares platforms and components with the Civic and has been included in some Honda-wide recall campaigns. A car sold private-party with under 30,000 miles and a single owner change is worth understanding before assuming the history is clean.

How to Run an Acura VIN Check: Step by Step

1. Locate the VIN through the windshield on the driver's side dashboard.
2. Cross-check with the door jamb sticker — both must match exactly. Any discrepancy is a hard stop until explained.
3. Confirm the first three characters are a recognized Acura WMI: 19U (US passenger car), 5J8 (US SUV/MPV), JH4 (Japan passenger car, older models), or 2HN (Canada SUV).
4. Verify the model year character at position 10 matches the year the seller states.
5. Note the plant code at position 11 — Marysville (M) builds sedans, East Liberty (F) builds SUVs, Performance Manufacturing Center (P) built the NSX.
6. Run the free NHTSA decoder to confirm specs and identify all open safety recalls by VIN.
7. Run the free NICB VINCheck to cross-reference national theft databases.
8. Enter the full 17-digit VIN into a trusted NMVTIS-approved provider for the complete history report.
9. Review accident history and title status first — then odometer records, ownership history, and open recall status.

Free vs Paid Acura VIN Check

The NHTSA VIN decoder and NICB VINCheck are both free and worth using — NHTSA confirms factory build specs and open recall campaigns, NICB checks theft records. What they can't surface is accident history, prior title events, or odometer inconsistencies across ownership transfers. Those require a paid report through an NMVTIS-approved provider.

For Acura specifically, the NHTSA tool does one thing especially well: it will surface open recall campaigns by VIN — and given that Acura models have been subject to multiple Honda-wide recall programs in recent years (airbag sensors, fuel pumps, FI-ECU software), this step alone is worth doing before any used Acura purchase. What NHTSA won't show is prior accident history across multiple states, a flood or salvage title brand that was applied in another jurisdiction, or the odometer records that reveal how a well-priced 2021 TLX actually accumulated 70,000 miles in 18 months. For vehicles in the $20,000–$50,000 range, a paid report is a straightforward due diligence step before any serious negotiation begins.

Frequently Asked Questions

What does 19U mean in an Acura VIN?

19U is the World Manufacturer Identifier for Acura passenger cars built in the United States. The "1" indicates the United States as the country of assembly, "9" identifies American Honda Motor Co. as the manufacturer, and "U" designates the passenger car vehicle type. This WMI covers the ILX, TLX, and Integra built at the Marysville, Ohio plant. Acura SUVs use 5J8 instead, and older Japan-built Acuras use JH4.

How do I know if an Acura MDX is US-built or Canadian-built?

The first character of the VIN tells you directly: "1" in position 1 means the MDX was assembled in the United States at Honda's East Liberty, Ohio plant. "2" in position 1 means it was built in Canada at Honda's Alliston, Ontario facility. Both plants have produced MDX models, and both are legitimate Acura-authorized facilities. The WMI for a Canadian-built Acura MDX is 2HN rather than 5J8. Neither origin is inherently preferable, but confirming the country of manufacture helps when researching VIN-specific recall history.

Are there open recalls I should check before buying a used Acura?

Yes — Acura has had significant recall activity in recent years across multiple model lines. Key campaigns include a 2024–2025 airbag seat weight sensor recall covering certain 2020–2022 MDX and RDX, and 2020–2021 TLX models (NHTSA 24V-064); a fuel pump failure recall covering 2013–2023 Acura ILX, MDX, RDX, and TLX (an expansion of NHTSA recall 21V-215); and the 2025 FI-ECU software recall (25V-031) covering TLX Type S and MDX Type S. Run the VIN through the NHTSA decoder at vpic.nhtsa.dot.gov to confirm which campaigns apply to the specific vehicle and whether each has been completed.

What is the difference between an Acura TLX and a TLX Type S by VIN?

The TLX and TLX Type S share the same WMI (19U) and are built at the same Marysville plant, but they carry different engine codes at position 8 — the base TLX uses a turbocharged 2.0L four-cylinder while the Type S uses a turbocharged 3.0L V6. The Type S is not directly named in the VIN, but the engine code at position 8 and the full VDS decode will identify the drivetrain. A vehicle presented as a TLX Type S should match the powertrain description when decoded — if it doesn't, the VIN does not belong to the car being sold.

Does an Acura VIN tell me if the car was used as a fleet or executive vehicle?

The VIN itself does not encode fleet use — that information appears in the ownership and title history recorded through NMVTIS. Multiple registered owners within a short period, or frequent state-to-state title transfers, are patterns that appear in a paid VIN history report and can indicate fleet, rental, or lease-return use. On Acura MDX and RDX models especially, which are popular corporate lease vehicles, checking the ownership history before purchase is a straightforward way to understand how the vehicle was actually used.
