Friend Codes are a randomly generated and unique twelve-digit number that is assigned to your Nintendo system for each Wi-Fi connection enabled game. They are only distributed upon connecting the game to the internet for the first time. Currently, only Metroid Prime: Hunters is capable of multiplayer Wi-Fi connection. Metroid Prime 3: Corruption uses WiiConnect24 and Wii Friend Codes only for the exchanging of Friend Vouchers. It is currently unknown whether Metroid: Other M will support the use of Friend Codes or Wi-Fi connection.
