You will see an American flag with 9 stars in the top left corner of government websites like the Centers for Disease Control and Prevention (CDC). The U.S. Web Design System shows this is the recommended official government site banner. It states that the banner helps people identify that the organization is a part of the government.

The U.S. State Department’s “ One Flag Policy ” mandates that only the American flag — except for specific instances, such as the POW/MIA flag — be flown at U.S. embassies around the world. To ensure a unified identity, this policy prohibits additional flags, including the Pride flag and the Black Lives Matter flag.
