An electronic or e-ticket is the newest reservation confirmation for booking reservations trains in Italy. This is exclusively available on trains that originate within Italy.
Upon completing an e-tickets booking, you will receive an email confirmation of your train journey in place of the printed and shipped tickets. This email will include the booking confirmation code, referred to as a "PNR," and the booking change code. This confirmation PNR will also include specific train information—date, time, number of passengers, fare code, and rules.
An e-ticket will either allow you to travel "ticketless"—boarding the train with only the PNR code—or will require you to "print a ticket upon departure" using one of the self-service machines at the train station. In general, high-speed trains will be ticketless and the regional, overnight, and cross-border trains will require you to print and validate your ticket before boarding your train for departure. Pay close attention to your email confirmations as the specific requirements of your train tickets are included.
