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 (4 U.S.C. § 1 et seq).

This is a U.S. federal law, but the penalty described in Title 18 of the United States Code
(18 U.S.C. § 700) for failure to comply with it is mostly not enforced. This etiquette is as applied
within U.S. jurisdiction. In other countries and places, local etiquette applies.
