A door hanger (also spelled doorhanger or door-hanger) is a plastic or cardboard sign, generally rectangular in shape, cut to hang from the handle or knob of a door. They are sometimes used to distribute print advertising to residences. Door hangers are often seen in hotels and other places of lodging as a means for guests to communicate with maintenance and housekeeping staff.
One common place where do not disturb signs are used is in places of lodging, where guests can place these signs on the door in order to inform staff, including housekeeping to respect their privacy. Some hotels also provide "make up room" signs giving the opposite instructions.
They are also used in schools to let other staff members and students at the school know that testing is in progress in the particular classroom.
Do not disturb signs are recommended to those who keep valuables in their rooms in order to deter possible thieves.
In 2009, a do not disturb sign was blamed for concealing the disappearance of an elderly couple on a cruise ship.
Some hotels are using high tech means to replace the paper do not disturb sign that hangs on the door. They are including a privacy button that one can press from the comfort of their room that lights up an indicator outside the room.
