It does not appear that there are any cheat codes for Pirates of the Caribbean, other than a few character codes. Also, there are only 20 characters to unlock using codes. For your benefit, the codes have been added here, in case you choose to use them. To use one of these codes, pause the game and choose Extras, from the menu. Here you will see an option to enter a code. Add the corresponding code in, for the character you wish to unlock.
