I know with the current game there a issue where if you made a char then put the item code you don't get the item. But i guess in 2.0 they can make it that a item is send by ingame mailbox but ya sadly you have to wait for 2.0

Also make sure you put the code in the right final fantasy xiv i put mine in my beta test and i had to chat with SE to give me a new code to put it on my real account and not the area that was for beta lol.
