Ohio State will use mobile-only ticketing beginning with the 2020 football season as one of several pandemic-related modifications announced Thursday in an email to season-ticket holders.

"Digital ticketing will allow for contactless entry for fans while also providing flexibility to easily manage their tickets," deputy athletic director Diana Sabau said in the email. "It will also allow us to better respond to the dynamics surrounding COVID-19 and our increased safety precautions."

The season-ticket deadline, which was previously extended twice, is Friday.

Seat selection will apply for only the 2020 season. The planned re-seating of Ohio Stadium for 2020 will now occur before next season. Seating for 2020 will be based on models that account for appropriate physical distancing.

Ohio State athletic director Gene Smith said earlier this month that he believes attendance will be limited from 20,000-50,000 for that reason.

Seat selection windows will be communicated by email at least five business days prior to the first selection window opening. That will allow fans to preview available seats.

If all or portions of the 2020 season are canceled, season ticket holders will have the option to get a refund for those tickets, receive a credit toward a future ticket purchase or donate their payment to support student-athlete scholarships.

Mobile tickets will be available for fans to access after they have selected their seats and paid in full. Options for season-ticket purchasers without smart phones will be announced later.

The renewal rate is at 85 percent. It was at 80 percent at the end of April.
