How a Mazda Mazda3 VIN is structured
Every Mazda carries a standardized 17-character VIN. The breakdown below uses a representative Mazda VIN JM3KFBCM6J0123456 to illustrate the structure: positions 1–3 and 9–17 follow the same federal standard for every Mazda3, while positions 4–8 (the descriptor section) are Mazda-defined and vary by model and year — read them as an example of the format, not a Mazda3-specific decode.
| Position | Section | In sample | What it encodes |
|---|---|---|---|
| 1–3 | World Manufacturer Identifier (WMI) | JM3 | Identifies Mazda and the country/region of build (JM1, JM3, JMZ, 4F2, 4F4). |
| 4–8 | Vehicle Descriptor Section (VDS) | KFBCM | Manufacturer-defined: model family, engine, and body/series. The exact meaning varies by make and model year. |
| 9 | Check digit | 6 | A calculated value that validates the other 16 characters. |
| 10 | Model year | J | Encodes the model year on a standardized 30-year cycle. |
| 11 | Assembly plant | 0 | Identifies the factory that built the vehicle. |
| 12–17 | Sequential number | 123456 | The unique production serial for this specific unit. |
JM1 and JM3 identify Mazda passenger vehicles built in Hiroshima, Japan. 4F2 identifies Mazda CX-50 built at the Mazda Toyota Manufacturing joint venture in Huntsville, Alabama. 4F4 has been used historically for Mexico builds. Decode your own VIN above for the exact values — the sample is illustrative of the format only.
Where Mazda builds it
- Hiroshima, Japan
- Hofu, Japan
- Salamanca, Mexico (Mazda3, CX-30)
- Huntsville, Alabama (CX-50)
The 11th VIN character identifies which plant built a specific Mazda3; the assembly plant is one of the facts the decode confirms.
Sources, data & limitations
Data source: VIN decoding returns manufacturer-reported attributes from NHTSA's vPIC database; recall campaigns and owner complaints come from NHTSA. Manufacturer-submitted fields vary by model year and market. Coverage: recalls and complaints are matched to the decoded year and model and do not confirm that this individual VIN has an unrepaired recall — verify exact-VIN status with Mazda or NHTSA. This free decoder does not include accident, title, odometer, or ownership history.

FAQ
What does a Mazda Mazda3 VIN decoder show?
Model year, trim level, engine and displacement, transmission, drive type, body style, and assembly plant for that exact Mazda3 — from manufacturer-submitted NHTSA vPIC data. CarWhere also cross-references open recalls, federal owner complaints, and verified buyer transaction prices for the same year and model.
Where is the VIN on a Mazda Mazda3?
Lower driver's-side corner of the windshield (visible from outside), the driver's door jamb sticker, the title, or the insurance card. JM1 and JM3 identify Mazda passenger vehicles built in Hiroshima, Japan. 4F2 identifies Mazda CX-50 built at the Mazda Toyota Manufacturing joint venture in Huntsville, Alabama. 4F4 has been used historically for Mexico builds.
Is the Mazda Mazda3 VIN decoder free?
Yes — free, no account, no lookup limit. The optional $9.99 Full VIN Report adds the original window sticker (where Mazda publishes one), itemized factory options, a recall and complaint scan, and a market price check with a negotiation target.
Can I check Mazda3 recalls and problems by VIN?
Yes — at the model level. Decoding the VIN pins the exact year and model, and CarWhere surfaces the open NHTSA recall campaigns and federal owner complaints filed for that year/model — useful for spotting known trouble areas before buying a used Mazda3. A campaign match does not by itself confirm this individual VIN has an unrepaired recall; verify exact-VIN status through NHTSA or a Mazda dealer (recall repairs are free for eligible vehicles).
