Mailbox

In every Animal Crossing game, including the Japan-exclusive Animal Forest, a red mailbox can be found outside the player's house. It is used as a place where letters from villagers from your town, a friend's town, the bellpoint, an item ordered from Tom Nook, the HRA ( Happy Room Academy ) and letters written by the player that have not yet been posted are stored. Even though a player can enter another player's house, only the owner of the house can open the mailbox of they're home. Letters can be found in the player's pockets by clicking a button at the top of the screen, but they must have been accessed here first.
