What Is a VIN and Why It Matters

A Vehicle Identification Number (VIN) is the unique serial code assigned to your truck at the factory. For Ford F100 buyers, sellers, and restorers, the VIN is the single most important piece of documentation on the vehicle. Depending on the era, it can tell you the truck series, where the truck was assembled, what engine it left the factory with, its position in the production sequence, and sometimes the model year. When you are evaluating a truck for purchase, the VIN is one way to check the seller's claims about year, originality, and equipment.

Ford's identification system evolved significantly across the F100's production run from 1948 to 1983. Early trucks used short serial numbers that conveyed limited standardized information. By the 1960s and 1970s, Ford used an 11-character truck VIN that identified series, engine, assembly plant, and sequence, but not always the model year directly. Then in 1981, the National Highway Traffic Safety Administration (NHTSA) mandated a standardized 17-digit VIN for all vehicles sold in the United States, which is the format still in use today. The final three F-100 model years -- 1981 through 1983 -- carry this modern 17-digit VIN.

Where you physically find the VIN on your truck also depends on its generation. On the earliest F-Series trucks, the number was stamped into the frame rail. Later models moved it to a plate on the door pillar, and from 1969 onward Ford began placing a VIN plate on the dashboard visible through the windshield. Knowing where to look -- and what format to expect -- is the first step in decoding your truck.

VIN Location by Generation

The table below shows where to find the VIN or serial number on each generation of the Ford F100. On older trucks, corrosion and body work can obscure these locations, so check all listed spots.

Generation Years VIN Location
1st 1948–1952 Left frame rail near the front of the truck
2nd 1953–1956 Left door pillar (hinge side) or left frame rail
3rd 1957–1960 Left door pillar (hinge side)
4th 1961–1966 Left door pillar; warranty plate on driver's door
5th 1967–1972 Door data plate; also dashboard visible through windshield (from 1969)
6th 1973–1979 Dashboard visible through windshield (driver's side); door data plate
7th 1980–1983 Dashboard visible through windshield (standardized 17-digit from 1981)

Pre-1953: 1st Generation (1948–1952)

The first-generation F-Series trucks used short serial numbers rather than the later standardized VIN layouts. Factory references show two source-backed patterns during this era: a 1948 through mid-September 1951 serial format, and a late-1951/1952 format that added the F-Series model code and a two-letter assembly-plant code.

The documented 1948 to mid-September 1951 format was:

[Model Year Code][Engine Code][Model Line][Sequential Number]

For example, a serial number like 87HC139260 breaks down as follows:

  • 8 -- 1948 model year
  • 7H -- 226 cubic-inch six-cylinder engine
  • C -- 1/2-ton pickup model line
  • 139260 -- Production sequence

Ford's 1949, 1950, and early-1951 trucks continued the 1949 serial-number group, so a leading 9 does not identify one exact model year by itself. Confirm the exact year from the title, registration, production records, or year-specific physical details.

The documented late-1951/1952 format was:

[Series Code][Engine Code][Model Year Code][Assembly Plant][Sequential Number]

For example, F1D2LU100001 decodes as F1 = F-1 1/2-ton, D = 215 I6, 2 = 1952, LU = Louisville, and 100001 = sequence number.

1953–1966: 2nd Through 4th Generation

Starting with the 1953 model year -- when the F-100 designation was first introduced -- Ford adopted more structured identification numbers, but the exact layout changed across the 1950s and 1960s. For 1953-1956 and 1957-1960 trucks, factory references show the VIN as series, engine, model year, assembly plant, and sequence. For 1961-1966 trucks, the common warranty-plate layout is series, engine, assembly plant, and sequence; the model year must be confirmed from the truck's documentation and year-specific references.

The documented 1953-1960 format was:

[Series Code][Engine Code][Model Year Code][Assembly Plant][Sequential Number]

A documented 1961-1966 format was:

[Series Code][Engine Code][Assembly Plant][Sequential Number]

  • Series Code: A three-character code such as F10 for F-100 2WD or F11 for F-100 4WD/light-duty applications.
  • Engine Code: A single letter identifying the factory engine. The meaning is year-dependent.
  • Model Year Code: Present in the documented 1953-1960 format. Second-generation trucks use 3, 4, 5, or 6; third-generation trucks use 7, 8, 9, or 0.
  • Assembly Plant: A single letter identifying the factory.
  • Sequential Number: A six-digit production sequence number, typically starting at 100001 for each plant and model year.

As examples, the documented 1953-style VIN F25D3U100001 decodes as: F25 = F-250 series, D = 215 I6, 3 = 1953, U = Louisville, 100001 = sequence number. The documented 1957-style VIN F25J7U100001 follows the same general order with updated year and engine-code tables.

During the 4th generation (1961--1966), Ford also added a warranty plate to the driver's door with additional data such as body color, trim, transmission type, axle ratio, and district sales code. This plate is valuable for restoration purposes even though the VIN itself remained relatively compact.

1967–1979: 5th and 6th Generation

The 5th generation "Bumpside" (1967--1972) and 6th generation "Dentside" (1973--1979) trucks used an 11-character VIN format. The core layout is series, engine, assembly plant, and sequence. For 1973-1979 trucks, Ford also used serial-number blocks that identify model year. For 1967-1972 trucks, the VIN itself does not directly encode model year, so confirm the year from the warranty plate, title, and year-specific details.

The 11-character format breaks down as follows:

Position Meaning Example
1–3 Truck series F10 = F-100 2WD
4 Engine code B = 300 I6 on many 1967-1979 trucks
5 Assembly plant U = Louisville
6–11 Sequential production number 100001

1973-1979 model years are inferred from the sequence block, not from the first character. Ford references list blocks such as Q00001-S60000 for 1973, S60001-V20000 for 1974, V20001-X40000 for 1975, A00001-D25000 for 1976, numeric and X80001-Z25000 blocks for 1977, AE0001-CK9999 for 1978, and DC0001-FK9000 for 1979.

Truck series codes include F10 for F-100 2WD pickup, F11 for F-100 4WD pickup, and source-backed chassis-cab or SuperCab rows such as F17, F18, X10, X14, and X17. Some codes are year-sensitive: X14 is source-backed as an F-100 4WD SuperCab for 1978-1979, while the 1980 Bullnose table uses X14 for an F-150 4WD SuperCab. Later 1970s and 1980 tables also include F-150, F-250, F-350, and Bronco series codes; the decoder surfaces those meanings with a warning when the VIN is not an F-100.

Engine Codes (1961–1980 11-Character VINs)

Position 4 of the 11-character VIN identifies the engine the truck was originally equipped with at the factory. The same letter can mean different engines in different years, so the decoder narrows the result when the year is known or can be inferred. This table is a representative sample of high-impact reused codes; use the tool above for the complete year-aware lookup.

Code Engine Notes
A 223 I6 / 240 I6 / 460 V8 223 economy six for 1961-1962 and 1964; 240 six for 1966 and 1967-1974; 460 V8 for 1975-1979
B 262 I6 / 300 I6 262 six for 1963-1964; 300 six for 1965-1966 and 1967-1979
D 292 V8 / 352 V8 292 4-barrel V8 for 1961-1964; 352 V8 for 1965
G 302 V8 (5.0L) 2V 1969-1979
H 390 V8 / 351M V8 390 for 1968-1976; 351M for 1977-1979
Y 352 V8 / 360 V8 352 for 1966-1967; 360 for 1968-1976
J 223 I6 / 240 I6 / 460 V8 223 six for 1961-1964; 240 six for 1965; 460 V8 for 1973-1979
1 240 I6 low-compression DSO 1973-1976 special-order low-compression engine code
5 360 V8 low-compression DSO 1974 special-order low-compression engine code
S 400 V8 (6.6L) 2V 1977-1979

Note that engine codes shifted across model years. A given letter could represent different displacements depending on the year. Always cross-reference the year, supplied model-year context, or 1973-1979 sequence block with the engine code when decoding.

Assembly Plant Codes

Position 5 identifies the assembly plant. Common plant codes for F-100 trucks include:

Code Plant Location
AAtlanta, GA
BOakville, Ontario, Canada
COntario, Canada
DDallas, TX
EMahwah, NJ
GChicago, IL
HLorain, OH

VKentucky Truck, KY

1980–1983: 7th Generation

The 7th and final generation of the F-100 spans 1980 through 1983 — known to enthusiasts as the Bullnose generation. The 1980 model year still used the older 11-character VIN format described above. Starting with the 1981 model year, Ford adopted the NHTSA-mandated 17-digit VIN format that remains the standard today. This makes 1981--1983 F-100 trucks significantly easier to decode, since the format is universal across all manufacturers.

17-Digit VIN Breakdown

Every position in the 17-digit VIN carries specific meaning:

Position Meaning F-100 Values
1 Country of origin 1 = United States, 2 = Canada
2 Manufacturer F = Ford Motor Company
3 Vehicle type T = Truck
4 GVWR / Brake type Varies; indicates gross vehicle weight rating class and brake system
5–7 Model / Body style F10 = F-100 2WD; F14, F15, X14, and X15 identify F-150 body/model codes
8 Engine code 3 = 230 V6 for 1982-1983 F-100, E = 300 I6 for 1981-1982 F-100, Y = 300 I6 for 1983 F-100, D = 255 V8, F = 302 V8
9 Check digit Computed value used to validate the VIN; not decoded manually
10 Model year B = 1981, C = 1982, D = 1983
11 Assembly plant Same plant code letters as earlier generations
12–17 Sequential production number Six-digit sequence unique to the plant and model year

For example, a VIN of 1FTCF10F4BKA00001 decodes as: 1 = USA, F = Ford, T = Truck, C = GVWR class, F10 = F-100 series, F = 302 V8 engine, 4 = check digit, B = 1981 model year, K = Kansas City plant, A00001 = production sequence.

The 9th-position check digit is calculated using a weighted formula applied to the other 16 characters. It exists to detect transcription errors and VIN fraud. If someone has altered a VIN, the check digit will not validate. While you can verify this manually, most online VIN decoders will flag a mismatched check digit automatically.

How to Use Your VIN

Verifying authenticity and matching numbers. On any F-100 built from the mid-1960s onward, a "numbers-matching" truck -- one with its original engine, transmission, and other major components -- is worth significantly more than one with swapped parts. The engine code in the VIN should correspond to the casting numbers on the block. If the VIN says your truck left the factory with a 302 V8 but the block is cast as a 351, you know the engine has been replaced. For pre-1967 trucks where the VIN carries less detail, the door data plate (when present) and factory build sheets are the best sources for verifying original equipment.

Determining original equipment. Beyond the engine, the door data plate on 4th-generation and later trucks can encode the original axle ratio, transmission type, paint color, trim level, and the sales district the truck was shipped to, depending on model year. Combined with the VIN, source-backed data plate fields give you a more complete picture of how the truck was originally configured. This is invaluable for correct restorations and for sourcing the right parts.

Title and registration considerations. When buying an F-100, always compare the VIN on the truck to the VIN on the title. On older trucks, previous owners may have inadvertently transposed digits when filling out paperwork, which can create issues at the DMV. If the VIN on the frame or data plate does not match the title, you will need to get the discrepancy resolved before the vehicle can be registered -- a process that varies by state and can be time-consuming. For trucks old enough to lack a dashboard VIN plate, some states may require a physical inspection to verify the VIN stamped on the frame rail. It is always better to catch these issues before you hand over money.

Data Plate Code Reference

Beyond the VIN, Ford F-100 trucks from the mid-1960s onward carried a door data plate with additional factory-build codes. These codes identify original paint, interior trim, transmission, rear axle ratio, body configuration, and the sales district that ordered the truck, though the exact field format changed by model year. For an interactive decoder, use the Data Plate Decoder tool.

Exterior Paint Color Codes

Ford used single-character codes on the data plate to identify the exterior paint color. These codes changed every model year. A few colors -- Raven Black (code A), Wimbledon White (code M), Chrome Yellow (code G), and Candyapple Red (code T) -- persisted across many years, but not always in uninterrupted year ranges. Below is a representative sample; for a complete year-by-year lookup, use the Data Plate Decoder.

CodeColor NameYears Available
ARaven Black1967–1971; 1973–1979
CPure White1967–1974

MWimbledon White1967–1979
TCandyapple Red1969–1979
SMidnight Blue Metallic1973–1979
JSilver Metallic1978

Two-tone paint was common on F-100 trucks. The data plate may show two color codes, with the first representing the upper body and the second the lower body.

Transmission Codes

The data plate transmission code identifies the factory-installed gearbox. These are representative source-backed rows; Ford reused several codes, so always decode against the specific model year.

Rear Axle Codes

Rear axle codes on the data plate identify the axle manufacturer, gear ratio, and whether the axle has a locking (Traction-Lok) differential. Letter codes indicate locking differentials; numeric codes indicate standard non-locking axles.

CodeRatioManufacturerLockingCapacity
023.00FordNo3,300 lb

C83.73Dana 60Yes5,200 lb
B44.10Dana 60Yes5,200 lb
D63.73Dana 70Yes7,400 lb

This is a representative sample. Ford used over 50 different axle codes across the F-100 production run. Use the Data Plate Decoder to look up your specific code.

Body Style Codes

The body code format changed by model year. On many 1967-1979 trucks, the final character or characters identify cab and bed configuration while the leading character or characters identify interior trim. The 1980-1983 certification-label body code combines bed, seat, and interior information and should not be decoded from a bed-only shorthand.

DSO District Codes

The DSO (District/Special Order) code identifies which Ford sales district originally ordered the truck. Ford reused and reorganized some district codes by year, and six-character DSO values use the first two characters as the district prefix. Common source-backed rows include:

Production Numbers

The following F-100 production figures come from published reference tables. Some sources disagree on exact model-year totals, and years without a source-backed F-100 total have been omitted rather than estimated.

YearF-100 ProductionNotes

1979225,893

The sharp drop in F-100 production from 1975 onward reflects the introduction of the F-150, which gradually absorbed most of the F-100's market. By 1977, F-150 production exceeded F-100 production, and the F-100 was discontinued entirely after the 1983 model year.
