Head over to Hulu’s gift page and enter your gift card’s redemption code—that’s it.
If you don’t have a Hulu account yet, you’ll be asked to make a new one. Once your gift card money runs out, your account will cancel on its own.
If you already have a Hulu subscription, you can redeem your Hulu gift card on your account page. After your gift card money is used up, your subscription will go back to using the card on file.
