The United States Flag Code establishes advisory rules for display and care of the national flag of the United States of America. It is Chapter 1 of Title 4 of the United States Code ( "et seq"). This is a U.S. federal law, but only suggests voluntary customs for handling of the American flag and was never intended to be enforceable. The code uses non-binding language like "should" and "custom" throughout and does not prescribe any penalties for failure to follow the guidelines.
