Okla. Stat. tit. 63 § 4020
Service Oklahoma shall notify through the mail, or via electronic mail, all persons who have not opted out of the notification system within the state who have previous vessel or motor registrations on record of the period for registration that are due to be registered in July of that year. Persons choosing to receive such annual notification through the mail shall be assessed an annual fee of fifty cents ($0.50), notwithstanding the provisions of Section 1114.1 of Title 47 of the Oklahoma Statutes, which shall be used by Service Oklahoma for printing and mailing of renewal notifications. Members of the Armed Forces of the United States,
the Reserve Corps of the Armed Forces of the United States, and the Oklahoma National Guard and their spouses eligible for the military registration fee, as provided in Section 4021 of this title, shall receive a renewal notification without payment of such fee. The printed notice shall contain all necessary information for such registration including a breakdown of all charges to be paid by the owner. The breakdown of the charges to be paid by the owner shall include the charges an owner would pay to register the vessel or motor for a one-year period and the charges an owner would pay to register the vessel or motor for a three-year period. Use of a postcard or electronic mail-type renewal notice is specifically permitted. The content and form of the notice shall also contain instructions as to the procedure for renewal upon presentation to a licensed operator or by return mail to Service Oklahoma's state office. Service Oklahoma shall provide information on its public website instructing persons on the procedure for obtaining an annual notification via electronic mail, free of charge, outlining all charges and fees associated with the registration of vessels and motors, as well as an explanation of the apportionment of vessel and motor registration fees and penalties. The cost of mailing shall be One Dollar ($1.00) for titles or other forms or devices required by the Oklahoma Vessel and Motor Registration Act. Provided, that Service Oklahoma may adjust any mailing costs as deemed appropriate to allow for increased or additional fees charged by the United States Postal Service.
Failure by any applicant to receive notification of renewal as provided by this section shall not excuse the applicant from properly obtaining any registration at the proper time by presenting proof of ownership to Service Oklahoma's state office or to a licensed operator.
