If you picked up a new copy of Final Fantasy XII at launch hopefully you held onto the little slip of paper with a code that was inside the box. If you did then you can use this code to get priority access to phase three of the Final Fantasy XIV: A Realm Reborn beta.
If you no longer have the code then don’t worry because if you registered your copy to your Square Enix Members account then the publisher will look it up for you. If you didn’t register the game then tough luck I’m afraid. If you registered the game you can visit this thread on the Square Enix forum to ask for help.
Once you have the code you can input it during your registration for the beta and it will greatly increase your chances of being selected for phase three which starts in June. North American fans can sign up for the beta here, and European fans here.
