JF4

The first three characters of every VIN are the World Manufacturer Identifier (WMI). The code JF4 is assigned to Saab, with the country of manufacture Japan.

So any 17-character VIN that begins with JF4 was produced by Saab:

JF4ZZZ0000000000000

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.
