Flags

at Post Offices

Post Offices were first required to display the American flag in 1885 to comply with Treasury Department instructions. As of Nov. 7, 2019, Post Offices are required to fly the Prisoner of War (POW)-Missing in Action (MIA) flag on the same days that the American flag is flown.
