Postal Service facilities should fly U.S. flags at half-staff Sept. 11 to honor victims of the 9/11 terrorist attacks.

President Joe Biden has ordered U.S. flags flown at half-staff Saturday, Sept. 11, to honor victims of the 9/11 terrorist attacks.

USPS facilities are required to fly the flag at half-staff this day, also known as Patriot Day and National Day of Service and Remembrance.

To fly the flag at half-staff, hoist the flag to the peak for an instant and then lower it to the half-staff position.

The flag should be raised to the peak again before it’s lowered for the day.

Facilities that fly the flag at all times and are closed Saturday should lower the flag to half-staff when the facility closes prior to Sept. 11. Return the flag to full staff when the facility opens on the next business day.

For additional information, refer to the Postal Service’s Administrative Support Manual, which explains the organization’s guidelines on U.S. flag display and maintenance.
