NPC flag
Pet flag (bottom)
An NPC Flag designates the home of the NPC shown on the flag. It is only visible while the housing interface is active. These flags can be placed out of the housing menu into any suitable home. Using ⚷ Open / Activate button on the flag in the home will remove the flag, allowing the player to reassign housing without an empty home. If the home is temporarily made unsuitable, the flag will not necessarily disappear. However, if the home is destroyed, the flag will find a nearby suitable home or disappear. At night, the NPC will stand at the location of their NPC flag within the home.
NPCs that move in on their own will have a regular red flag (except for Town pets(Desktop, Console and Mobile versions), which use a purple flag instead). On the 
Desktop version, 
Console version, and 
Mobile version, if the player assigns them to a home, the flag will have a golden frame. This indicates that if the NPC currently inhabiting the home were to die, the replacement for that NPC would move into that specified home.
