Every Subaru Impreza (2017–2023) carries a 17-character VIN that begins with the 4S3 WMI. The Impreza is a gas sedan; this page shows what each character of a Subaru Impreza 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 Impreza.
Each sample below is built from the real 4S3 WMI and the Impreza's descriptor, so it decodes to a Subaru Impreza of the right model year:

Worked on the sample 4S3GKAB69HH221612 — a 2017 Subaru Impreza:
| Position | Section | Value | What it tells you |
|---|---|---|---|
| 1–3 | WMI | 4S3 | Marks the VIN as Subaru, built in United States |
| 4–8 | VDS | GKAB6 | Descriptor for the Impreza — sedan body, gas powertrain |
| 9 | Check digit | 9 | Mod-11 checksum over the other 16 characters |
| 10 | Model year | H | Code H = 2017 |
| 11 | Plant | H | Assembly-plant code |
| 12–17 | Serial | 221612 | Sequential production number |
Positions 1–3 of every Subaru Impreza VIN read 4S3 — the World Manufacturer Identifier that marks the vehicle as Subaru, assembled in United States (North America). After the WMI, positions 4–8 (GKAB6 in our seed) describe the Impreza itself; see the full 17-digit format.
Position 10 encodes the model year. For the Impreza, 2017 is code H and 2023 is code P. See the 2023 year code or the check-digit math.

A Subaru Impreza VIN is 17 characters starting with the 4S3 WMI, for example 4S3GKAB69HH221612. Positions 4–8 describe the Impreza, position 9 is the check digit, position 10 is the model year, and 12–17 are the serial number.
Read it left to right: 4S3 is the Subaru WMI, positions 4–8 are the Impreza 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 Impreza in our seed uses the 4S3 WMI (United States). Any VIN beginning with 4S3 decodes to Subaru.
No. They are synthetically generated but checksum-valid, use the real Subaru 4S3 WMI, and carry the Impreza's descriptor and a valid year code — so a decoder returns a Subaru Impreza. No real vehicle's VIN is used.
