Every Nissan Altima (2019–2024) carries a 17-character VIN that begins with the 1N4 WMI. The Altima is a gas sedan; this page shows what each character of a Nissan Altima 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 Altima.
Each sample below is built from the real 1N4 WMI and the Altima's descriptor, so it decodes to a Nissan Altima of the right model year:

Worked on the sample 1N4BL4BV0KN627034 — a 2019 Nissan Altima:
| Position | Section | Value | What it tells you |
|---|---|---|---|
| 1–3 | WMI | 1N4 | Marks the VIN as Nissan, built in United States |
| 4–8 | VDS | BL4BV | Descriptor for the Altima — sedan body, gas powertrain |
| 9 | Check digit | 0 | Mod-11 checksum over the other 16 characters |
| 10 | Model year | K | Code K = 2019 |
| 11 | Plant | N | Assembly-plant code |
| 12–17 | Serial | 627034 | Sequential production number |
Positions 1–3 of every Nissan Altima VIN read 1N4 — the World Manufacturer Identifier that marks the vehicle as Nissan, assembled in United States (North America). After the WMI, positions 4–8 (BL4BV in our seed) describe the Altima itself; see the full 17-digit format.
Position 10 encodes the model year. For the Altima, 2019 is code K and 2024 is code R. See the 2024 year code or the check-digit math.

A Nissan Altima VIN is 17 characters starting with the 1N4 WMI, for example 1N4BL4BV0KN627034. Positions 4–8 describe the Altima, position 9 is the check digit, position 10 is the model year, and 12–17 are the serial number.
Read it left to right: 1N4 is the Nissan WMI, positions 4–8 are the Altima 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 Altima in our seed uses the 1N4 WMI (United States). Any VIN beginning with 1N4 decodes to Nissan.
No. They are synthetically generated but checksum-valid, use the real Nissan 1N4 WMI, and carry the Altima's descriptor and a valid year code — so a decoder returns a Nissan Altima. No real vehicle's VIN is used.
