Regulations for Proper Flag Display The United States Postal Service® periodically reprints part 47 of the Administrative Support Manual (ASM), so postmasters can ensure that the American flag, the Postal Service™ flag, and the MIA-POW flag are properly displayed.

To read all of the regulations concerning the display of flags at Postal Service facilities, see blue.usps.gov/cpim/ftp/manuals/asm/asmtc.pdf.
