Friend Code

Friend Codes are strings of twelve numbers used to allow access to another person's town during online play, more commonly known as Wi-Fi. Both players must have registered each other's friend code. A friend code looks like ####-####-####, (three sets of four digits,, where #'s represent numbers. To get someone's friend code, the player must go to the Town Gate and talk to Copper. He or she then must select "Friend Code!" and Copper will assign a friend code, though there should be Wi-Fi Connection from a router or USB cable for it to work. Once the friend code is obtained, a person can trade a code with a friend and visit each other's towns. If only one person has registered the code, it will not work.

Friend codes were introduced in and later used in  and. However, in all 3DS games, including New Leaf, the friend code system uses the friend code stored on the 3DS system rather than issuing a separate friend code for each game. Friend codes are not to be confused with Dream Addresses used for visiting a 'dream' version of another player's town in the Dream Suite.
