Every Subaru Ascent (2019–2024) carries a 17-character VIN that begins with the 4S4 WMI. The Ascent is a gas SUV; this page shows what each character of a Subaru Ascent 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 Ascent.
Each sample below is built from the real 4S4 WMI and the Ascent's descriptor, so it decodes to a Subaru Ascent of the right model year:

Worked on the sample 4S4WMACD3KC520533 — a 2019 Subaru Ascent:
| Position | Section | Value | What it tells you |
|---|---|---|---|
| 1–3 | WMI | 4S4 | Marks the VIN as Subaru, built in United States |
| 4–8 | VDS | WMACD | Descriptor for the Ascent — SUV body, gas powertrain |
| 9 | Check digit | 3 | Mod-11 checksum over the other 16 characters |
| 10 | Model year | K | Code K = 2019 |
| 11 | Plant | C | Assembly-plant code |
| 12–17 | Serial | 520533 | Sequential production number |
Positions 1–3 of every Subaru Ascent VIN read 4S4 — the World Manufacturer Identifier that marks the vehicle as Subaru, assembled in United States (North America). After the WMI, positions 4–8 (WMACD in our seed) describe the Ascent itself; see the full 17-digit format.
Position 10 encodes the model year. For the Ascent, 2019 is code K and 2024 is code R. See the 2024 year code or the check-digit math.

A Subaru Ascent VIN is 17 characters starting with the 4S4 WMI, for example 4S4WMACD3KC520533. Positions 4–8 describe the Ascent, position 9 is the check digit, position 10 is the model year, and 12–17 are the serial number.
Read it left to right: 4S4 is the Subaru WMI, positions 4–8 are the Ascent 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 Ascent in our seed uses the 4S4 WMI (United States). Any VIN beginning with 4S4 decodes to Subaru.
No. They are synthetically generated but checksum-valid, use the real Subaru 4S4 WMI, and carry the Ascent's descriptor and a valid year code — so a decoder returns a Subaru Ascent. No real vehicle's VIN is used.
