In New Leaf, if two guests are on the same town but are not each other's friends, they may add each other in the Guest List at the bottom screen. Prior to the introduction of Dodo Codes, two players must add each other as friends before they may visit each other.

Two players must add each other's Friend Code so that they can be friends. From New Leaf onwards, Friend Codes and Friends are assigned on a system level. In Wild World and City Folk, a Friend Code was obtainable for the first time by talking to Copper and saying "Friend Code!" This would connect to the Nintendo Wi-Fi Connection to assign the player a code. The icon used when registering a Friend Code in City FolkĪ Friend Code is a 12-digit code that identifies any player.
