The registration code for the "Spore" game is located in the manual that came with the game. The manual is found within the case containing the game CD.
In order to play the EA game "Spore," players must first purchase the game. Codes which are often found on the Internet are either already registered to a player's account, invalid, or illegal. Using an illegal code will usually lead to EA revoking a player's ability to access the game, causing him to lose any progress within the game.
If a player has previously purchased the game and is unable to locate the registration code for another install, that player can contact EA support to retrieve the lost information.
