G Suite is available in most countries and regions.
However, Google restricts access to some of its business services in certain countries or regions, such as China, Crimea, Cuba, Iran, North Korea, Sudan, and Syria. If you try to sign in to these services from these countries or regions, the following error appears:
You appear to be signing in from a country where G Suite accounts are not supported.
Certain Google services might be available in these countries or regions for personal use, but not for business or education use.
