About the Ford Explorer
The Ford Explorer went on sale in March 1990 as a 1991 model, replacing the compact Bronco II and building on the Ranger pickup platform. It is widely credited, alongside the Jeep Grand Cherokee, with popularizing the modern American SUV, and it became the best-selling SUV in the United States for most of the 1990s and 2000s. Since 1991 the Explorer has gone through six generations:
| Generation | Years | Chassis code | Body | Built at |
|---|---|---|---|---|
| 1st | 1991-1994 | UN46 | Body-on-frame, Ranger-based | Louisville, KY / St. Louis, MO |
| 2nd | 1995-2001 (Sport/Sport Trac to 2005) | UN105 | Body-on-frame | Louisville, KY / St. Louis, MO |
| 3rd | 2002-2005 | U152 | Body-on-frame, independent rear suspension | Louisville, KY / St. Louis, MO |
| 4th | 2006-2010 | U251 | Body-on-frame, last of the type | Louisville, KY |
| 5th | 2011-2019 | U502 | Unibody crossover, D4 platform | Chicago, IL |
| 6th | 2020-present | U625 | Unibody, rear-wheel-drive-based CD6 platform | Chicago, IL |
The fifth generation is the single biggest engineering change in the model’s history: Ford dropped the truck-style body-on-frame chassis it had used since 1991 and moved the Explorer onto a unibody platform shared with the Ford Flex and Lincoln MKT. The sixth generation moved again, onto the rear-wheel-drive-based CD6 platform it now shares with the Lincoln Aviator.
Note: Ford also sells a European “Explorer EV,” built in Cologne, Germany, on Volkswagen’s MEB platform. It shares only a badge with the American SUV covered here. Every code on this page refers to the US-market, gas-and-hybrid Explorer.
Ford Explorer WMI codes (positions 1 to 3)
The first three characters of a VIN form the World Manufacturer Identifier, assigned by SAE International on behalf of ISO. Genuine North American Ford Explorers carry:
| WMI | Country | Notes |
|---|---|---|
| 1FM | USA | Ford SUV built in the United States; the standard Explorer WMI across all six generations |
Unlike some model lines Ford builds worldwide, the domestic Explorer has been assembled exclusively at US plants since 1991, so 1FM is effectively the only WMI on a genuine US-title Explorer. If a VIN begins with anything else, run it through the decoder above before trusting the paperwork; a mismatched WMI is one of the simplest signs of a cloned or rebadged vehicle.
How to decode a Ford Explorer VIN, position by position
Every Explorer built since 1991 uses the 17-character ISO 3779 standard. The string breaks into three blocks, and each character carries specific meaning.
Positions 1 to 3: World Manufacturer Identifier
See the table above: 1FM on every domestic Explorer. The first character (1) is the country of build (USA), the second (F) is the manufacturer (Ford), and the third (M) encodes vehicle class (SUV/MPV).
Positions 4 to 8: Vehicle Descriptor Section (VDS)
This works a little differently on Ford than on some other brands. Positions 4 and 5 carry an internal Ford series code (DU, ZU, EU, 5K, and SK all appear across Explorer years), but that code mixes body style, restraint system, and trim rather than spelling out the generation in plain letters. The reliable way to identify generation is model year (position 10) plus the chassis-code range in the table above, or just run the VIN through the decoder at the top of this page.
Position 8 is more useful on its own: it’s the engine code, and Ford keeps it reasonably consistent within each generation. Codes confirmed directly against NHTSA’s VIN database:
| Generation | Char | Engine |
|---|---|---|
| 1st (UN46) | X | 4.0L Cologne V6 OHV, 155-160 hp |
| 2nd (UN105) | P | 5.0L V8 EFI, 215 hp (Limited/Eddie Bauer option) |
| 3rd (U152) | K | 4.0L SOHC V6, 210 hp |
| 3rd (U152) | W | 4.6L Modular SOHC V8, 239 hp |
| 4th (U251) | E | 4.0L SOHC V6, 210 hp |
| 5th (U502) | 8 | 3.5L Ti-VCT V6 (naturally aspirated), 290 hp |
| 6th (U625) | H | 2.3L EcoBoost turbo I4, 300 hp |
| 6th (U625) | C | 3.0L EcoBoost twin-turbo V6 (ST/Platinum) |
Ford also fitted other engines within some of these generations: a 4.6L V8 on the 4th gen, 2.0L and twin-turbo 3.5L EcoBoost options on the 5th gen, a 3.0L hybrid on the 6th gen. We haven’t independently verified every one of those position-8 characters against NHTSA data, so if your engine code isn’t above, don’t guess; the decoder at the top of this page returns the exact factory engine for your specific VIN.
Position 9: Check digit
The check digit catches typos. It’s calculated from the other 16 characters using a fixed weighting table and modulo-11 math. Mistype a single character anywhere in the VIN and the math no longer matches; any compliant decoder, every state DMV, and the NHTSA recall database will reject the entry. That’s why “look up by VIN” beats “look up by license plate” when you need to confirm a specific vehicle.
Position 10: Model year
The 10th character maps to model year on a 30-year cycle, the same cycle used across the entire industry:
| Char | Year | Char | Year | Char | Year |
|---|---|---|---|---|---|
| M | 1991 | 5 | 2005 | H | 2017 |
| N | 1992 | 6 | 2006 | J | 2018 |
| P | 1993 | 7 | 2007 | K | 2019 |
| R | 1994 | 8 | 2008 | L | 2020 |
| S | 1995 | 9 | 2009 | M | 2021 |
| T | 1996 | A | 2010 | N | 2022 |
| V | 1997 | B | 2011 | P | 2023 |
| W | 1998 | C | 2012 | R | 2024 |
| X | 1999 | D | 2013 | S | 2025 |
| Y | 2000 | E | 2014 | T | 2026 |
| 1 | 2001 | F | 2015 | ||
| 2 | 2002 | G | 2016 | ||
| 3 | 2003 | ||||
| 4 | 2004 |
The letters I, O, and Q are skipped because they resemble 1 and 0. The cycle repeats every 30 years: P was 1993 and is again 2023. Since the Explorer has run continuously since 1991, use the chassis-code range above (no U625 existed in 1993) to resolve any ambiguity.
Position 11: Assembly plant
A single character identifies the specific factory. We confirmed each of these directly against NHTSA’s decoder using real Explorer VINs from that plant’s production years:
| Char | Plant | Years active for Explorer |
|---|---|---|
| U | Louisville, Kentucky | 1991-2010 |
| Z | Hazelwood (St. Louis), Missouri | 1991-2006 (plant closed March 2006) |
| G | Chicago, Illinois | 2011-present |
Positions 12 to 17: Serial number
The final six characters are the production sequence stamped on your specific Explorer as it left the line. Combined with the previous 11, this makes every Explorer VIN globally unique, even two built the same year at the same plant with the same engine.
Explorer trim levels and how they appear in the VIN
A Ford Explorer VIN does not spell out the trim name directly; trim is reconstructed from the VDS plus the build sheet, the same way the decoder above does it. Common North American Explorer trims by generation:
- 1st gen (1991-1994): Base/XL, XLT, Eddie Bauer
- 2nd gen (1995-2001): XL, XLT, Eddie Bauer, Limited (added 1996), Sport (3-door)
- 3rd gen (2002-2005): XLS, XLT, Eddie Bauer, Limited
- 4th gen (2006-2010): XLS/XLT, Eddie Bauer, Limited, Ironman Edition
- 5th gen (2011-2019): Base, XLT, Limited, Sport (added 2013), Platinum (added 2016)
- 6th gen (2020-present): Base, XLT, ST-Line, Limited, Timberline, ST, Platinum, plus a hybrid Limited variant
When you decode an Explorer VIN above, the result also returns drivetrain (RWD, 4WD, AWD, or FWD-based AWD depending on generation) and factory equipment groups, so you can match a build sheet or window sticker.
Where to find the VIN on a Ford Explorer
Several locations on every Explorer, plus the paperwork:
- Lower-left corner of the windshield, visible from outside the vehicle
- Driver’s side door jamb sticker (also carries tire spec and GVWR)
- Stamped on the engine block or frame rail, depending on generation
- Vehicle title, registration, insurance card, FordPass app
The windshield and door jamb are easiest to read on a used-vehicle lot. Check the block or frame stamp if you suspect a cloned or altered VIN; it’s physically tied to the vehicle and much harder to swap than a plate or sticker.
Ford Explorer recalls and safety
The Explorer’s most infamous safety episode is the 2000 Firestone tire recall: Bridgestone/Firestone recalled roughly 14.4 million ATX, ATX II, and Wilderness AT tires, most fitted to second-generation Explorers, after tread-separation failures were linked to rollover crashes. That episode was primarily a tire defect, not one encoded in the Explorer’s VIN, and it led directly to the federal TREAD Act and today’s standard tire-pressure-monitoring systems. Worth knowing, but not something a VIN decode can flag on its own.
More recent, VIN-relevant recalls include:
- 2011-2019 (5th gen): A-pillar trim retention clips that may not engage properly, allowing interior trim to detach
- 2018-2019 (5th gen): Manual front seat-back recliner mechanisms that could fail to lock
- 2020-2022 (6th gen): A rear-axle bolt and subframe bushing that can fracture, creating a rollaway risk even with the shifter in Park; roughly 253,000 vehicles were recalled
- 2022 (6th gen): A fuel line fitting that may not be fully tightened at the factory
To check your specific Explorer:
- Decode the VIN with the tool above to confirm the exact model year and generation
- Cross-reference the 17-character VIN with Ford’s recall lookup or NHTSA’s recall database
- Contact your nearest Ford dealer’s service department for any open campaign repair
Recall repairs are free regardless of vehicle age, mileage, or ownership history.
Frequently asked questions
How do I decode a Ford Explorer 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: generation, model year, engine, trim, transmission, drivetrain, assembly plant, and any open NHTSA recalls. No sign-up required.
Where is the VIN on a Ford Explorer?
The lower-left corner of the windshield, readable from outside, and the driver-side door jamb sticker. Both are required by federal labelling regulation. Depending on generation, the same number is also stamped on the engine block or frame rail.
What generation is my Explorer based on the VIN?
Combine the model year at position 10 with the chassis-code range above: UN46 for 1991-1994, UN105 for 1995-2001, U152 for 2002-2005, U251 for 2006-2010, U502 for 2011-2019, U625 for 2020-present. The plant code at position 11 (U Louisville, Z St. Louis, G Chicago) narrows it further, since Louisville and St. Louis both stopped Explorer production before the 5th generation began.
Was the Firestone tire recall a Ford VIN defect?
No. The 2000 recall covered Firestone-brand tires fitted to certain second-generation Explorers, not a manufacturing defect encoded in the Explorer’s own VIN or chassis. It’s important history, but a VIN decode reflects factory-built configuration and open manufacturer recalls, not tire-supplier issues from decades ago.
Is the Ford Explorer VIN decoder really free?
Yes. VinDecoderPlus decodes every Ford Explorer VIN free of charge with no sign-up. The basic decode covers everything the factory stamped into the VIN. A full vehicle history report (accident records, odometer history, prior ownership, salvage status) is available as a paid upgrade if you need it.
Can a Ford Explorer VIN be faked?
The 17 characters can be retyped on a counterfeit plate, but the check digit at position 9 catches most single-character changes through math, and the engine-block or frame stamp is physically tied to the original vehicle. If the windshield and door-jamb VINs match but the frame or block stamp doesn’t, the vehicle may be cloned. The guide how to check if a car is stolen by VIN walks through the verification steps.
