Got my standard edition box today in the mail, and registered my game.

There also was a smaller paper with a 6-3-6-3 code on it.

When I typed in the address to see what this was to put in: http://member.square-enix.com/na it auto takes me to the japanese site for this.

Does anyone know what this is for? Something about Members Community and get promotions etc.

I thought if you went to http://na.square-enix.com/en/home I could put it somewhere but it says invalid code.
