| CH is Switzerland's ISO country code. ISO (internation organization for standardization) refers to codes for the representation of names of countries and their subdivisions.
germany's is de, austria's is at, france is fr ...
Browsing a political map of Switzerland, you'll notice that each of the twenty-six cantons also has one of these two letter codes.

I hope that clears things up for you. | |
