Greetings,

To clarify those asking about where their CE items are:

New users who purchased the FINAL FANTASY XIV: A Realm Reborn Collector's Edition
The registration code (PC) and promotion code (PS3) that you will need to register will be included inside your copy of the game when you receive it.
The pre-order code you redeemed grants early access and the two in-game bonus items (Moogle Cap/Cait Sith Doll minion) and not the CE items.

If you purchased via the PlayStation Network, the codes are already registered on the back end and will show up with connecting your Sony Entertainment Network account to your Square Enix account.

If you purchased a PC digital download edition, the retailer you purchased it from will send you your registration code when the game launches in your respective territory.
For your reference, the North American Square Enix Online store will send them out at 12 a.m. PDT.
