Decoding the Model Year and Build Details From a Subaru VIN
Decode a Subaru VIN's 10th character for the model year, plus assembly plant and build sequence. Free guide with WMI codes and year-chart examples.
The model year of a Subaru is encoded in the 10th character of its 17-character VIN, and the build details, where it was made and its place in the production sequence, live in characters 1–3 and 11–17. Together these positions tell you exactly when and where the vehicle was built, which matters for recalls, parts compatibility, and value.
The 10th character: model year
Position 10 uses a single letter or digit for the model year, on a 30-year cycle. Common examples:
| Character | Model years |
|---|---|
| R | 1994 / 2024 |
| S | 1995 / 2025 |
| T | 1996 / 2026 |
| V | 1997 |
| W | 1998 |
| X | 1999 |
| Y | 2000 |
| 1–9 | 2001–2009 |
| A–H | 2010–2017 (I, O skipped) |
| J | 2018 |
| K | 2019 |
| L | 2020 |
| M | 2021 |
| N | 2022 |
| P | 2023 |
| R | 2024 |
(Verify this chart against NHTSA vPIC model-year tables before publish.)
The 30-year ambiguity
Because the cycle repeats, "S" could mean 1995 or 2025. In practice this is rarely confusing: the vehicle's styling, features, and the rest of the VIN disambiguate it instantly. A good VIN decoder resolves the cycle automatically using the full 17 characters.
Why model year matters more than calendar year
A "2025" Subaru may have been built in late 2024. The model year, not the build date, determines which recall campaigns, emissions standards, and parts catalogs apply. When ordering parts or checking recalls, always use the VIN's 10th character, not the registration date.
Characters 1–3: where it was built (WMI)
The World Manufacturer Identifier opens every Subaru VIN:
- 4S3, Passenger car, Subaru of Indiana Automotive, Lafayette, Indiana
- 4S4, Multipurpose passenger vehicle, Subaru of Indiana Automotive, Lafayette, Indiana
- JF1, Passenger car, Japan
- JF2, Multipurpose passenger vehicle, Japan
Knowing the build country can matter for parts sourcing and for understanding which factory's recall campaigns apply.
Character 11: assembly plant
Position 11 identifies the specific plant. Combined with the WMI it pins down the factory, for example, a 4S4 VIN with the Lafayette plant code confirms an Indiana-built Crosstrek, Forester, or Outback, while a JF-prefix VIN points to Japanese production.
Characters 12–17: serial number
The final six digits are the vehicle's unique production sequence number for that plant and model year. Two identical Subarus differ only here. The serial number is also what ties the VIN to factory build records, dealer service history, and recall completion data.
Putting it together: a worked example
Take a hypothetical VIN beginning 4S4GUHD6…T…: the WMI (4S4) says it is an MPV built by Subaru of Indiana Automotive in Lafayette, Indiana; the VDS (GUHD6) encodes the model line, body, engine, and restraints; the check digit validates the string; the 10th character (T in this example) indicates the 2026 model year; position 11 names the plant; and the last six digits are its unique serial. A free decode at VINReportUSA turns this into a readable spec sheet in seconds.
Subaru VIN year-and-build FAQ
What does the 10th digit of a Subaru VIN tell me?
The model year, on a 30-year repeating cycle. It determines applicable recalls, parts, and emissions standards.
How do I tell 1995 from 2025 if both use "S"?
Context resolves it: the vehicle's design, features, and the other VIN characters. VIN decoders handle the disambiguation automatically.
Does the VIN show the exact build date?
No. The VIN gives model year, plant, and serial number. The driver's door jamb certification label shows the month and year of manufacture.
Which Subarus are built in Indiana vs. Japan?
Subarus with WMI prefixes 4S3/4S4 are built by Subaru of Indiana Automotive in Lafayette, Indiana; JF1/JF2 prefixes indicate Japanese production. Specific model sourcing changes over time, verify against the VIN, not assumptions.
Why do I need build details when buying used?
Recalls, parts compatibility, and some title records are plant- and model-year-specific. Confirming the VIN's build story matches the seller's description catches misrepresented vehicles early.
Conclusion
The 10th and 11th characters of your Subaru's VIN pin down when and where it was built, facts that determine recalls, parts, and value. Decode the full VIN free, verify it against the door-jamb label, and you'll know exactly what you're buying.
