Hi, welcome to FFXIV!

How to enter Code:
1. Go to the Mog Station and log in or create a new account.
2. Select "Your Account".
3. Click "Manage Service Options".
4. Click "Enter Recruitment Code".
5. Enter the code: 2PY86ES7

Or you could watch this video where he explains what you get for free and how to enter the Code. I found it very helpful.
