– make the telephone number field required 
– add required fields for the postal address (street and house number, postal code, city)

Create and manage online registrations with ease. Design your own registration layout and manage bookings.
SeatReg is built around a visual seat map. You design the layout in the map builder, add it to your site with a shortcode or share it as a direct link, and manage the bookings that come in. Visitors open the map, select a seat, and complete their booking.
It is commonly used for events and conferences, theaters and cinemas, classes and workshops, restaurants and venues, churches, and coworking spaces — situations where people reserve a specific seat or spot.
