Are the bus tickets e-tickets?

Yes, in general, bus tickets are e-tickets. After a successful booking, you will receive a booking confirmation immediately by email. The booking number you have to show to the bus operator. It helps to print the PDF file and show it to the employees/driver. Some bus operators, e.g. Panthip, insist in having a printed voucher.
For some operators passengers are required to furnish the following at the time of boarding the bus: a copy of the ticket (a print out of the ticket or the print out of the ticket e-mail) and proof of identity (Domestic Smart ID Card, Driving license, Student ID card, Company ID card, Passport, etc.).Failing to do so may cause the passenger not being allowed for boarding.
