What Code "F" Means
Under NHTSA's VIN standard (effective since 1981), position 10 of every VIN encodes the model year using a single letter or digit from a fixed table. The letter F maps to the model years 1985 and 2015.
Ambiguous code — two possible years
The code F repeats every 30 years. A VIN with this code could be from 1985 or 2015. To determine the actual year, check the NHTSA full decode (which uses the full VIN to confirm the year), the vehicle's title, or the manufacturer's label on the door jamb.
