To decode a 2020-or-newer Ford Explorer VIN, read positions 5 through 7 first. Ford's filings use a three-character code there: K7 means rear-wheel drive, K8 means four-wheel drive, and the letter after it is the trim (B Base, D XLT, F Limited, G ST, H Platinum, and so on). Position 8 is the engine: H for the 2.3-liter four, B for the 3.3-liter V6, W for the 3.3-liter hybrid and C for the 3.0-liter twin-turbo V6. Position 10 is the year and position 11 is the plant, where G means Chicago Assembly.
We read Ford's own Part 565 VIN filings for the 2020, 2022 and 2026 model years in NHTSA's vPIC library on November 8, 2026. That is the current-generation Explorer only. If you are looking at a 2011 to 2019 truck, the layout is different and this guide will mislead you, so stop here and use our general Ford VIN decoder instead. And honestly, the reason this matters is money. An ST and an ST-Line look close enough in listing photos, and one of them has a 400 hp twin-turbo engine.
The first four characters
Every Explorer table we read starts with 1FM, which Ford defines as Ford Motor Company, USA, multipurpose passenger vehicle. Position 4 is not the model. It is the brake system and GVWR code. In the 2020 and 2022 filings, 5 means hydraulic brakes with a 6,001 to 7,000 lb GVWR, and S means 5,001 to 6,000 lb. The 2026 filing lists 5 again, plus U and W, each tied to a GVWR class and a restraint package. So two Explorers of the same trim can differ at position 4 just because of how heavy the configuration is, and that is not a red flag on its own.
Positions 5 to 7: drive and trim
This is the code people care about. In the 2020 filing the list was short: K7B Base, K7D XLT and K7F Limited in rear drive, then K8A Police, K8B Base, K8D XLT, K8F Limited, K8G ST and K8H Platinum in four-wheel drive. Notice the ST and Platinum only showed up as 4WD that first year.
By the 2022 filing Ford had added a lot. Rear-drive codes now include K7H Platinum, K7L King Ranch, K7G ST and K7K ST-Line, and the 4WD side adds K8L King Ranch, K8K ST-Line and K8J Timberline. The 2026 filing is different again: K7D and K8D are now labeled Active, K7H and K8H Platinum, K7G and K8G ST, K7K and K8K ST-Line, K8A Police, and K8J has become Tremor. So the same letter, D, meant XLT in 2022 and Active in 2026, and J meant Timberline in 2022 and Tremor in 2026. A one-size decoder chart will get that wrong, and that is exactly how a wrong trim ends up copied into a listing. If the year matters to the trim, check the year first and the trim second.
Position 8: which engine is under the hood
The engine letters have stayed fairly stable across the three filings, though the 2022 sheet is the only one of the three that lists horsepower:
- H is the 2.3-liter EcoBoost four, 300 hp in the 2022 table (the 2020 table said 270).
- B is the 3.3-liter V6, 285 hp in 2022.
- W is the 3.3-liter hybrid, 318 hp in 2022.
- C is the 3.0-liter twin-turbo V6, 400 hp in 2022.
The 2020 table also lists Y for a 3.0-liter plug-in hybrid, a code the 2022 and 2026 tables no longer include. Here is where we would slow down: an ST should carry a C. If a seller swears it is an ST and position 8 is an H, either the badges came from a parts catalog or someone typed the trim wrong. Both are worth knowing before you pay ST money, and the same check works for a hybrid: an Explorer sold as a hybrid should show a W at position 8, not a B. Our guide to decoders that show the wrong trim covers what to do when the paperwork and the car disagree.
Positions 9 to 17
Position 9 is the check digit, worked out from the other 16 characters under 49 CFR 565.15. A single typo usually breaks it, which makes it a handy fraud filter, and our check digit explainer walks through the math. Position 10 is the year: L for 2020, N for 2022 and T for 2026 in these filings, and the 10th digit guide has the full table.
Position 11 is G for Chicago Assembly in all three. The 2022 filing also lists N as the Chicago SHO Center, so do not panic if you see an N there on a 2022. Positions 12 to 17 are the sequence number, which Ford lists as A00001 to F99999 for the Explorer.
Worked example, then the stuff the VIN cannot tell you
Take a made-up 2022 VIN that starts 1FM5K8GC, then a check digit, then NG. Reading it: Ford MPV, 6,001 to 7,000 lb class, 4WD ST, 3.0-liter twin turbo, 2022, Chicago Assembly. That is a consistent ST. Swap the C for an H and the story falls apart.
Then run the full VIN through NHTSA's free vPIC decoder and compare. A clean decode only describes how the truck left Chicago, though. It says nothing about the rear axle bolt recall that hit these years, which we cover in our Explorer rear axle bolt recall guide, and nothing about crashes, flood title brands or odometer gaps. Check open recalls with Ford's recall lookup by VIN and read the generation notes in our used Explorer buying guide.
For history, a single CARFAX bought on CARFAX's own site usually runs about $39.99 to $44.99, give or take. CarVins is a licensed reseller of CARFAX and AutoCheck reports, not owned by or affiliated with CARFAX, AutoCheck or Experian, and lately a guest report here has been around $5.50, roughly $4.50 for members, and about $6.75 for both reports together. Those numbers move, so confirm at checkout before you pay. Whatever you do, do not trust a PDF the seller emails you. Pull the report yourself from the VIN you just decoded.
