And while that is an option, like I mentioned, it's not the most common one.

The wikipedia link to America, redirects to the United States of America: https://en.wikipedia.org/wiki/America

And in the description of the United States of America: The United States of America (USA), commonly referred to as the United States (U.S.) or America
