What these rules cover
Srbijavoz sells domestic tickets at ticket offices, machines, and through eKarta. From July 21, 2026, the carrier also opened online sales of international tickets for trains to Montenegro and the Subotica–Szeged–Subotica route. Electronic-ticket rules depend on the specific train, accommodation type, or vehicle-transport booking.
Why the rules differ
For domestic travel, the carrier states that online purchases receive a 5% discount; it does not apply to international tickets. There are also separate ticket-document rules: they determine when an electronic ticket is enough and when a paper copy is needed before boarding.
Current display and printing rules
For a sleeping car, couchette car, or vehicle transport, print the ticket and show it to staff before boarding. According to Srbijavoz's July 21 notice, on night train 433/432 Zemun–Bar–Zemun and seasonal daytime train 1131/1130 Subotica–Bar–Subotica, a regular-seat ticket or reservation may be shown in the app or printed from the PDF sent by email. Without a printout, a ticket for sleeping or couchette accommodation or vehicle transport is not valid for boarding.
Why it matters to passengers
Checking only the route is not enough: confirm the accommodation type and whether a vehicle is being carried. For an ordinary seat on the two named trains to Bar, the app or PDF is sufficient; for sleeping or couchette accommodation and vehicle transport, print the ticket before boarding. For travel within Serbia, the usual eKarta rules and surcharge for buying a ticket on board apply.
What to check before travelling
Before paying, first check the train number, accommodation type, and vehicle transport: those determine whether a phone is enough. Then confirm in eKarta that the selected international route is available. If a train or accommodation type is not named in the official notice, do not assume its electronic-display rule applies without checking with Srbijavoz.
