The nation will observe National POW-MIA Recognition Day Sept. 19. This is one of six days a year all USPS facilities are required to fly the POW-MIA flag.
The flag and its display honor the sacrifices made by members of the armed forces held as prisoners of war or missing in action.
A list of the six days USPS facilities are required to fly the POW-MIA flag can be found in Administrative Support Manual Section 476.1.
Postmasters and station managers should regularly inspect U.S. and POW-MIA flags flown at their postal facilities to make sure they’re serviceable and displayed with respect. When a flag is tattered, faded or otherwise no longer a fitting emblem for display, it must be immediately replaced.
Postmasters and station managers can order U.S. and POW-MIA flags through eBuy2.
