2CK

The first three characters of every VIN are the World Manufacturer Identifier (WMI). The code 2CK is assigned to Geo, Pontiac, with the country of manufacture Canada.

So any 17-character VIN that begins with 2CK was produced by Geo, Pontiac:

2CKZZZ0000000000000

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.
