How do I obtain and use my 18 digit pre-order code?

This will depend on where you pre-ordered the game, so please confirm directly with the retail outlet.

*Note that the pre-order bonus codes are different for the Playstation 3 and Windows versions of the game, so please ensure you receive a code for the correct platform at the time.
*Pre-order codes will be available from Aug 1st, 2013.

How do I use my 18-digit pre-order code?

Customers who have pre-ordered FINAL FANTASY XIV: A REALM REBORN will receive an 18-digit pre-order code (hereafter referred to as the ‘pre-order code’) from their retailer.

You will be able to redeem this pre-order code on the Pre-order Rewards Code Redemption website here from the 20th August 2013. You will also receive a reminder email containing full redemption instructions from your retailer on the same day.

After redeeming your pre-order code, you will then receive an email with a 20-character alphanumeric Pre-order Bonus code.
Instructions included in this email will prompt you to register the Pre-order Bonus code on the Pre-order code registration page here. Please follow these instructions carefully to ensure you add your Early Access & bonus items to the correct service account.

Please note this website opened on 9th August, 2013 for Japanese account holders but EU account holders will only be able to register the code from the 20th August, 2013.

*If you haven’t received your pre-order code, please contact your retailer directly. 
*If you have pre-ordered the PC version of the game from the Square Enix Store, you will receive the Pre-order Bonus code (20 digit) by email on the 20th August.
*Note that the 18-digit pre-order code is for the PC version only. If you have pre-ordered the PS3 version of the game, you will receive your Pre-order Bonus code directly from your retailer.
