JF

The first three characters of every VIN are the World Manufacturer Identifier (WMI). The code JF is assigned to Fuji Heavy Industries (Subaru), with the country of manufacture Japan.

So any 17-character VIN that begins with JF was produced by Fuji Heavy Industries (Subaru):

JFZZZ0000000000000

The WMI only identifies the maker. To read the year, engine, plant and serial number, decode the complete 17-digit VIN with our free tool — then check which ECU it uses and what tuning services (DPF, EGR, AdBlue, DTC off, Stage) are available.
