According to this State Department web page, the U.S. counts 197 independent states. I think 226 is probably the total number of polities the U.S. has had diplomatic relations with over time.
The fact that the U.S. has acknowledged Germany and its present-day borders seems to me a de facto recognition that polities like East Germany, Bavaria and Braunschweig-Lüneburg are no longer sovereign states.
