A VIN describes how a vehicle was built. It cannot describe where it was shipped, and no decoder anywhere changes that. The free GCC spec check reads your VIN, gives a verdict with a certainty score and the evidence behind it, and lists the physical and documentary checks that settle what the VIN cannot, starting with the GSO conformity lookup. The full VIN decoder returns every attribute the decode resolves, and the Toyota page explains the scheme above position by position.
Common questions
Is there a character in a VIN that means GCC?
There is no universal one, and any site that says otherwise is wrong. A small number of manufacturers do write a destination field into the VIN on particular models, and the Toyota Coaster is one of them: position 7 of its descriptor is 1 for the Gulf and 2 for Australia. Nissan does the same at position 10 on its export cars. Those are specific manufacturer schemes, not a standard.
