Every Subaru Legacy (2020–2024) carries a 17-character VIN that begins with the 4S3 WMI. The Legacy is a gas sedan; this page shows what each character of a Subaru Legacy 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 Legacy.
Each sample below is built from the real 4S3 WMI and the Legacy's descriptor, so it decodes to a Subaru Legacy of the right model year:

Worked on the sample 4S3BWAF67LC838084 — a 2020 Subaru Legacy:
| Position | Section | Value | What it tells you |
|---|---|---|---|
| 1–3 | WMI | 4S3 | Marks the VIN as Subaru, built in United States |
| 4–8 | VDS | BWAF6 | Descriptor for the Legacy — sedan 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 | 838084 | Sequential production number |
Positions 1–3 of every Subaru Legacy 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 (BWAF6 in our seed) describe the Legacy itself; see the full 17-digit format.
Position 10 encodes the model year. For the Legacy, 2020 is code L and 2024 is code R. See the 2024 year code or the check-digit math.

A Subaru Legacy VIN is 17 characters starting with the 4S3 WMI, for example 4S3BWAF67LC838084. Positions 4–8 describe the Legacy, 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 Legacy 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 Legacy 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 Legacy's descriptor and a valid year code — so a decoder returns a Subaru Legacy. No real vehicle's VIN is used.
