Per the Universal Website: Ticket is for purchase and use by Florida Residents only. Guest must present proof of Florida residency at time of purchase and ticket pick-up. It also says tickets are non-transferable.

While a Florida resident can physically purchase Universal Orlando tickets for out-of-state friends, those friends cannot use Florida Resident-specific discounted tickets. Universal requires each adult using a resident-priced ticket or pass to provide their own valid proof of Florida residency at the gate or when activating the ticket. This usually involves a Florida driver's license, a Florida state ID, or a voter registration card. If a resident buys a discounted multi-day ticket for an out-of-state guest, that guest will likely be stopped at the turnstile and required to pay the "price difference" to upgrade to a standard non-resident ticket before being allowed entry. However, a Florida resident can buy standard, non-discounted tickets for their friends as a gift without any residency issues. The residency requirement is strictly enforced to ensure that the significant discounts offered to locals are not exploited by tourists, so it is always best for out-of-state guests to have their own standard tickets to avoid delays and extra costs at the park entrance.
