FFXIV on ps4 and pc

I purchased the subscription which allows me multiple characters the ps4 I just put together a gaming rig and want to play ffxiv. the only concern is I would have 2 monthly subscriptions. I would hope that my subscription would carry over but I highly doubt it.

Register your PC code on the same Square Enix account and it will fall under the same subscription. You can play your account on both PS4 and PC.
