Every Subaru Outback (2020–2025) carries a 17-character VIN that begins with the 4S4 WMI. The Outback is a gas wagon; this page shows what each character of a Subaru Outback 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 Outback.
Each sample below is built from the real 4S4 WMI and the Outback's descriptor, so it decodes to a Subaru Outback of the right model year:

Worked on the sample 4S4BTAFC7LC629924 — a 2020 Subaru Outback:
| Position | Section | Value | What it tells you |
|---|---|---|---|
| 1–3 | WMI | 4S4 | Marks the VIN as Subaru, built in United States |
| 4–8 | VDS | BTAFC | Descriptor for the Outback — wagon body, gas powertrain |
| 9 | Check digit | 7 | Mod-11 checksum over the other 16 characters |
| 10 | Model year | L | Code L = 2020 |
| 11 | Plant | C | Assembly-plant code |
| 12–17 | Serial | 629924 | Sequential production number |
Positions 1–3 of every Subaru Outback 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 (BTAFC in our seed) describe the Outback itself; see the full 17-digit format.
Position 10 encodes the model year. For the Outback, 2020 is code L and 2025 is code S. See the 2025 year code or the check-digit math.

A Subaru Outback VIN is 17 characters starting with the 4S4 WMI, for example 4S4BTAFC7LC629924. Positions 4–8 describe the Outback, 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 Outback 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 Outback 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 Outback's descriptor and a valid year code — so a decoder returns a Subaru Outback. No real vehicle's VIN is used.
