This page is the dedicated Forester hub, one level more detailed than our general Subaru guide. Below you’ll find the six chassis codes the Forester has carried since 1997, the WMI codes specific to this model, a verified position-by-position breakdown (including where the engine actually shows up in the VIN, since it isn’t where some other brands put it), trim levels by generation, and notable Forester recalls.
About the Subaru Forester
Unveiled in Japan in 1997 and arriving at US dealers that same year as a 1998 model, the Forester was one of the first true compact crossover SUVs, ahead of most rivals that tried to blend wagon practicality with SUV ride height. It was built on an Impreza-derived platform, kept the boxer-engine/symmetrical-AWD layout Subaru uses across its lineup, and built a reputation on boxy visibility and strong crash-test scores rather than styling flair. It has run through six chassis generations:
| Generation | Years (US model year) | VIN code (positions 4-5) | Platform | Built at |
|---|---|---|---|---|
| 1st (SF) | 1998-2002 | SF | Impreza-derived | Ota, Gunma, Japan |
| 2nd (SG) | 2002-2008 | SG | New Impreza platform | Ota, Gunma, Japan |
| 3rd (SH) | 2008-2013 | SH | Larger crossover dimensions, same Impreza base | Ota, Gunma, Japan |
| 4th (SJ) | 2013-2018 | SJ | Impreza-based | Ota, Gunma, Japan; Tan Chong (Malaysia CKD) from 2016 |
| 5th (SK) | 2018-2025 | SK | Subaru Global Platform | Ota, Gunma, Japan; TCSAT, Thailand |
| 6th (SL) | 2025-present | SL | Updated Subaru Global Platform | Ota, Gunma, Japan; Lafayette, Indiana (from MY2026) |
Two things worth knowing about that last row: the redesigned sixth-generation model launched partway through model year 2025, and for a few months Subaru actually shipped both codes at once. VINs decoded through NHTSA vPIC show 2025 Forester Wilderness models still carrying the SK code (built in Japan) while 2025 Sport, Premium, and Touring trims of the same new-generation car already carried SL. By model year 2026, SL covers every trim, and that’s also the year Forester assembly shifted to Subaru of Indiana Automotive (SIA) in Lafayette for the US market, alongside continued Japan-built production for other markets.
Subaru Forester WMI codes (positions 1-3)
Real Forester VINs, verified through NHTSA vPIC, use three World Manufacturer Identifiers:
| WMI | Country | Notes |
|---|---|---|
| JF1 | Japan | Forester, SF and SG generations (1998 through roughly 2008), coded as a passenger car |
| JF2 | Japan | Forester, SH through SL generations (2008-present), coded as a multipurpose vehicle |
| 4S4 | USA | Forester built at Subaru of Indiana (Lafayette), confirmed from model year 2026 |
If your Forester’s VIN doesn’t start with one of these, treat it as suspect and confirm with a full decode above. Note the JF1-to-JF2 switch lines up with NHTSA reclassifying the Forester’s body type as it grew from wagon-like to full crossover SUV around the SH generation, not with any change of manufacturer.
How to decode a Subaru Forester VIN, position by position
Positions 1-3: World Manufacturer Identifier
Covered above. Position 1 is the country of assembly, not Subaru’s headquarters location; a Lafayette-built Forester is a full Subaru product, just with a US-registered WMI instead of a Japan-registered one.
Positions 4-8: Vehicle Descriptor Section (VDS)
Position 4 is always S for Forester. Position 5 carries the generation letter, and it lines up cleanly with the chassis codes above:
| Char (pos. 5) | Generation |
|---|---|
| F | SF (1998-2002) |
| G | SG (2002-2008) |
| H | SH (2008-2013) |
| J | SJ (2013-2018) |
| K | SK (2018-2025, and early MY2025 Wilderness) |
| L | SL (2025-present) |
Position 6 is where the engine lives, but be aware Subaru resets what each character means with every redesign, so there’s no single letter that always equals “turbo” across the Forester’s history. Verified examples pulled from real, checksum-valid VINs decoded through NHTSA vPIC:
| Generation | Pos. 6 | Confirmed engine |
|---|---|---|
| SF | 6 | 2.5L flat-4 (EJ25), naturally aspirated |
| SG | 6 | 2.5L flat-4, both the naturally aspirated EJ25 and the turbo EJ255 XT decode to 6; trim/turbo status is carried at position 7 instead |
| SH | 6 or G | 2.5L turbo flat-4 (EJ255), XT trim; the character varied between model years in our samples |
| SJ | A | 2.5L flat-4 (FB25), naturally aspirated |
| SJ | G | 2.0L turbo flat-4 (FA20), 2.0XT trim |
| SK | A | 2.5L flat-4 (FB25), Wilderness tune, 182 hp |
| SL | D | 2.5L flat-4 (FB25), standard trims, 180 hp |
| SL | S | 2.5L flat-4 hybrid (FB25 plus twin electric motors), Forester Hybrid, 162 hp from the engine alone, 194 hp combined |
Position 7 layers in trim and equipment level on top of the engine code; position 8 covers the restraint system fitted (airbag count and seatbelt configuration) per federal requirements. Because positions 6 through 8 interact rather than reading as independent lookups, the decoder above is the reliable way to resolve an exact configuration rather than reading the VIN by eye.
Position 9: Check digit
Calculated from the other 16 characters using SAE’s weighting formula and modulo-11 math. A single mistyped character anywhere in the VIN breaks this math, and NHTSA’s database, state DMVs, and this decoder will all flag the VIN as invalid.
Position 10: Model year
The 10th character follows the standard 30-year ISO cycle used across the industry:
| Char | Year | Char | Year | Char | Year |
|---|---|---|---|---|---|
| W | 1998 | 7 | 2007 | J | 2018 |
| X | 1999 | 8 | 2008 | K | 2019 |
| Y | 2000 | 9 | 2009 | L | 2020 |
| 1 | 2001 | A | 2010 | M | 2021 |
| 2 | 2002 | B | 2011 | N | 2022 |
| 3 | 2003 | C | 2012 | P | 2023 |
| 4 | 2004 | D | 2013 | R | 2024 |
| 5 | 2005 | E | 2014 | S | 2025 |
| 6 | 2006 | F | 2015 | T | 2026 |
| G | 2016 |
I, O, and Q are always skipped since they’re easily confused with 1 and 0. The Forester’s first US model year (1998) used W, so unlike some longer-running nameplates the cycle hasn’t repeated yet on this model.
Position 11: Assembly plant
A single character identifies the specific factory and, on Japan-built cars, the transmission type:
| Char | Plant | Notes |
|---|---|---|
| G | Ota, Gunma, Japan | Manual transmission, AWD |
| H | Ota, Gunma, Japan | Automatic/CVT, AWD (the most common code by far) |
| 3 | Lafayette, Indiana, USA (SIA) | Confirmed on MY2026 US-market Foresters |
Positions 12-17: Serial number
The final six digits are the production sequence number stamped on your specific Forester as it left the line, making the full 17-character string globally unique even for two Foresters built the same day at the same plant.
Forester trim levels and how they show up in the VIN
The VIN doesn’t spell out trim by name directly; it’s reconstructed from the VDS block plus the factory build sheet, which is exactly what NHTSA vPIC and the decoder above do. Confirmed trim ladders by generation:
- SF (1998-2002): base, L, S
- SG (2002-2008): X, XS, 2.5X, 2.5XT (turbo, added 2004), Limited
- SH (2008-2013): 2.5X, Premium, Limited, Touring, 2.5XT (turbo Premium/Limited/Touring)
- SJ (2013-2018): 2.5i, Premium, Limited, Touring, 2.0XT (turbo, Premium/Touring only)
- SK (2018-2025): Base, Premium, Sport, Limited, Touring, Wilderness (added for 2022)
- SL (2025-present): Premium, Sport, Limited, Touring, Wilderness, plus Hybrid versions of Sport and Touring
Where to find the VIN on a Subaru Forester
- Lower-left corner of the windshield, visible from outside the vehicle
- Driver’s side door jamb sticker (also lists tire pressure, paint, and trim codes)
- Stamped on the engine bay firewall or front frame rail
- Vehicle title, registration, insurance card, and the MySubaru app on newer cars
The windshield and door jamb are the fastest checks on a used-car lot. The firewall stamp is worth verifying if you suspect a title has been swapped between two Foresters, since it’s tied to the chassis rather than a removable sticker.
Subaru Forester recalls and safety
Several Forester-specific NHTSA campaigns are worth checking regardless of generation:
- Turbo secondary air injection pump relay (2009-2013 SH, XT trim): The relay could fail, letting the pump overheat and potentially melt, raising fire risk. Subaru issued a 2016 recall after at least one reported fire.
- Takata passenger airbag inflator (2010-2013 SH): Part of the broader industry-wide Takata campaign; the inflator could rupture and send metal fragments into the cabin.
- Turbo intake duct crack (2015-2016 SJ, 2.0XT trim): Built between April and October 2015, the turbo air intake duct could crack and cause the engine to stall.
- Engine water pipe leak (2024 SL): Loose attachment bolts could let the water pipe lose its seal, leaking coolant onto a hot exhaust pipe and raising fire risk.
- Fuel cap seal (2025-2026 SL, Hybrid trims): An insufficient fuel cap seal could let fuel expand and leak near an ignition source when the tank is nearly full.
To check your specific Forester:
- Decode the VIN with the tool above to confirm the exact model year and generation
- Cross-reference the 17-character VIN with Subaru’s recall portal or NHTSA’s recall database
- Contact your nearest Subaru retailer for any open campaign repair
Recall repairs are free regardless of the vehicle’s age, mileage, or ownership history.
Frequently asked questions
How do I decode a Subaru Forester VIN?
Type the 17-character VIN from the windshield, door jamb, or title into the decoder at the top of this page. Results return in seconds and include generation (SF through SL), model year, engine, trim, transmission, plant of origin, and open NHTSA recalls. No sign-up required.
Where is the VIN on a Subaru Forester?
The two fastest spots are the lower-left corner of the windshield, readable from outside the car, and the driver-side door jamb sticker, both federally required labels. The engine bay firewall carries a physical stamp matching the same number.
How do I tell the generation of my Forester from the VIN?
Look at position 5. F is first-gen SF (1998-2002), G is SG (2002-2008), H is SH (2008-2013), J is SJ (2013-2018), K is SK (2018 through early 2025), and L is the redesigned SL generation (2025-present). Position 10 then confirms the exact model year.
What does a Forester VIN starting with 4S4 mean?
4S4 is the WMI for Subaru of Indiana Automotive in Lafayette, confirmed on model year 2026 Foresters. Before that, every Forester sold in the US carried a Japan-registered WMI (JF1 or JF2), since the Forester wasn’t built at SIA until the sixth-generation redesign moved US production there.
Is the Subaru Forester VIN decoder really free?
Yes. VinDecoderPlus decodes every Forester VIN free with no sign-up. The decode covers everything the factory stamped into the VIN. A full vehicle history report (accidents, odometer history, prior ownership, salvage status) is available as a paid upgrade if you need it.
Can a Subaru Forester VIN be faked?
The 17 characters can be reprinted on a counterfeit plate, but the check digit at position 9 catches most single-character changes through math, and the firewall stamp is physically tied to the original car. If the windshield and door-jamb VINs match but the firewall stamp doesn’t, treat the car as potentially cloned. The guide how to check if a car is stolen by VIN walks through the verification steps.
