A voucher is a type of document that passenger receives after paying for the order. There are two types of vouchers - exchangeable and non-exchangeable.

An exchange voucher is a type of document that must be exchanged for a boarding pass at the box office of the departure bus station.

A non-exchange voucher is a type of voucher that does not need to be changed to a boarding pass, but must be printed and provided to the driver directly when boarding the bus.

On the form of the voucher that you receive after payment of the order, it will be indicated whether it is subject to a mandatory exchange on hand or not. This information is indicated at the top of the document. Please note that regardless of the type of voucher, it is necessary to print it.
