The 2009 Suzuki Alto for international markets is a rebadged Maruti A-Star, which is different than the Japanese Alto, and is supposed to be a design of Maruti.
I believe that the models Maruti Suzuki A-Star, 2009+ Suzuki Alto for EU and the rebadged Nissan Pixo should be listed with Indian origin flag at this point.

The Linkedin page of Maruti Suzuki's head of design Saurabh Singh seems to confirm this:

Does this concern all with code FC31S, compared to HA25S being the Japanese one?

Yes exactly

Updated.
A few Alto without chassis code still have to be updated manually.
I also changed the hatchback to supermini, as there was a mix of both.
