To decode a Ford or Lincoln VIN, read it in three blocks: positions 1-3 tell you the maker and vehicle type (1FA is a US-built Ford car, 1FT a Ford truck, 1FM an SUV or van, 3FA a Mexico-built car), positions 4-8 describe the line, body, and engine, and position 9 is a math check. Position 10 is the model year, 11 is the plant, and 12-17 are the serial. A clean decode only proves what the truck should be, so pull a history report before you pay.
As of mid October 2026 we keep seeing F-150 and Explorer listings that post a decoder screenshot in place of a history report. That screenshot can be real and the truck can still have a branded title in another state. So treat this page as step one. It is the Ford-specific companion to our general guide on how to decode a VIN, and it follows the same federal layout we used in the Toyota VIN decoder guide.
Positions 1-3: the Ford WMI tells you country and vehicle type
The first three characters are the World Manufacturer Identifier, and on a Ford they mostly tell you where the vehicle was built and what kind of vehicle it is. We ran the common prefixes through NHTSA's free vPIC decoder this week. 1FA came back as Ford Motor Company, passenger car. 1FT is a truck, 1FM is a multipurpose passenger vehicle (think Explorer, Expedition, Bronco), and 1FD is an incomplete vehicle, which is what you see on chassis-cab Super Duty trucks that got an upfitted body. 3FA and 3FT decode as Ford Motor Company, Mexico, for cars and trucks. 2FM is Ford of Canada. Lincoln uses its own prefixes, such as 1LN for cars and 5LM for SUVs, and vPIC still lists the maker as Ford Motor Company.
If the WMI says car and the listing says truck, stop there. Honestly, that one mismatch catches more typo VINs and copied VINs than anything else on this page.
Positions 4-8: line, body, drive, and engine
The vehicle descriptor section is where Ford encodes the model line, cab or body style, drive, restraint and weight class details, and the engine. The rules for what must be there live in 49 CFR Part 565, but the exact letter meanings are Ford's, and Ford reuses them across years. In our test decodes, a pattern starting 1FTEW1EG with a 2016 year code returned an F-150 pickup, 4WD, 3.5-liter engine. A pattern starting 1FTFW1E5 with a 2021 year code returned an F-150 with the 5.0-liter V8. Position 8 is the engine slot on these trucks, and that is the character to stare at when a seller swears the truck has the V8.
Do not decode position 8 from a forum chart. The same letter can point to different engines in different model years, so always read it together with position 10, or just paste all 17 characters into vPIC. If you are shopping diesel Super Duty trucks, our Power Stroke history report guide covers what the decode will not tell you about fleet use and engine work.
Position 9: the check digit catches fakes and typos
Position 9 is calculated from the other 16 characters. Under 49 CFR 565.15, each character gets a number, each position gets a weight, the weighted sum is divided by 11, and the remainder becomes 0-9 or X. We tested a dummy pattern, 1FTEW1EG0GKA00000, and vPIC said the check digit was correct. Change just the plant letter from K to F and the same check digit fails. That is the whole point. A VIN typed wrong on a listing, or a VIN someone made up for a fake title, usually breaks the math.
A passing check digit does not prove the VIN belongs to that truck. Cloners copy real VINs from legit vehicles, so the math passes on purpose. Our page on how to spot VIN cloning covers the physical checks.
Positions 10-17: model year, plant, serial
Position 10 is the model year. Recent codes run F for 2015, G for 2016, H for 2017, J for 2018, K for 2019, L for 2020, M for 2021, N for 2022, P for 2023, R for 2024, S for 2025, and T for 2026. Letters I, O, Q, U, and Z are never used, and neither is zero. Position 11 is the plant. In our decodes, F came back as Dearborn, Michigan, K as Kansas City, Missouri, and 5 as Flat Rock, Michigan on a Mustang pattern. Positions 12-17 are the production sequence.
Then go look at the metal. Match the VIN on the dash plate, the driver door-jamb certification label, and the title, character by character. Our walkthrough on finding and verifying a VIN lists the other stamped and printed spots. A door label that looks newer than the rest of the jamb is a reason to slow way down.
Why history still matters after a clean Ford decode
The decode answers what the truck was built as. It says nothing about the flood claim, the auction announcement, the odometer swap, or the open recall. Recalls are a good example of why the VIN alone is not enough. Ford's April 2026 recall report 26V237 covers about 1.39 million 2015-2017 F-150s with the 6-speed automatic for an unintended downshift into second gear, and Ford states those trucks were not built in VIN order. So you cannot guess from the serial. Run the specific VIN through the lookup in our NHTSA recall check by VIN guide.
For the history itself, CARFAX's vehicle history reports page explains that the data comes from DMVs, insurers, auctions, and service shops, none of which is encoded in the VIN. Pull your own report. A seller PDF can be edited, and we still see trimmed ones. As of mid October 2026, a CARFAX report through us runs about $5.50 as a guest or about $4.50 as a member, and a CARFAX plus AutoCheck bundle is about $6.75, against roughly $39.99 to $44.99 at retail. Prices change, so confirm at checkout. We are a licensed CARFAX and AutoCheck reseller, not affiliated with CARFAX, AutoCheck, or Experian.
