Every Mazda MX-5 Miata (2019–2024) carries a 17-character VIN that begins with the JM1 WMI. The MX-5 Miata is a gas convertible; this page shows what each character of a Mazda MX-5 Miata VIN means and gives 4 checksum-valid sample VINs you can drop straight into test fixtures. Synthetic — not real: no scraping, no real-owner data. The generator below is pre-filtered to the MX-5 Miata.
Each sample below is built from the real JM1 WMI and the MX-5 Miata's descriptor, so it decodes to a Mazda MX-5 Miata of the right model year:

Worked on the sample JM1NDAD75K5894820 — a 2019 Mazda MX-5 Miata:
| Position | Section | Value | What it tells you |
|---|---|---|---|
| 1–3 | WMI | JM1 | Marks the VIN as Mazda, built in Japan |
| 4–8 | VDS | NDAD7 | Descriptor for the MX-5 Miata — convertible body, gas powertrain |
| 9 | Check digit | 5 | Mod-11 checksum over the other 16 characters |
| 10 | Model year | K | Code K = 2019 |
| 11 | Plant | 5 | Assembly-plant code |
| 12–17 | Serial | 894820 | Sequential production number |
Positions 1–3 of every Mazda MX-5 Miata VIN read JM1 — the World Manufacturer Identifier that marks the vehicle as Mazda, assembled in Japan (Asia). After the WMI, positions 4–8 (NDAD7 in our seed) describe the MX-5 Miata itself; see the full 17-digit format.
Position 10 encodes the model year. For the MX-5 Miata, 2019 is code K and 2024 is code R. See the 2024 year code or the check-digit math.

A Mazda MX-5 Miata VIN is 17 characters starting with the JM1 WMI, for example JM1NDAD75K5894820. Positions 4–8 describe the MX-5 Miata, position 9 is the check digit, position 10 is the model year, and 12–17 are the serial number.
Read it left to right: JM1 is the Mazda WMI, positions 4–8 are the MX-5 Miata descriptor, position 9 verifies the VIN via a mod-11 checksum, position 10 gives the year, position 11 the plant, and 12–17 the serial. Paste any VIN into the decoder to do it automatically.
The MX-5 Miata in our seed uses the JM1 WMI (Japan). Any VIN beginning with JM1 decodes to Mazda.
No. They are synthetically generated but checksum-valid, use the real Mazda JM1 WMI, and carry the MX-5 Miata's descriptor and a valid year code — so a decoder returns a Mazda MX-5 Miata. No real vehicle's VIN is used.
