Acho que você pode usar uma senha. Consulte a página Opções de compra da Greyhound :
Gift Ticket Orders (GTO) are available for purchase on this website. GTO allows you to purchase a ticket online for another person. This ticket is delivered to the departure bus station, under the following criteria:
- The buyer pays a non-refundable gift ticket fee at time of purchase, regardless of number of tickets purchased
- Tickets may not be sent outside the U.S.
- Both stations must be open at the time of the transaction and of ticket pick-up
- Buyer and recipient should allow three hours from time of purchase to departure time to complete the transaction
- Appropriate ID or a password is required to pick up the ticket [emphasis added!]
- Only the purchaser may cancel the ticket or apply for a refund
Ah, sim, tenho certeza agora. Consulte também a seção "Ligar para" em "Tipos de tickets on-line" :
Will Call tickets allow you to purchase a ticket online and then pick it up at the counter. If the credit card holder is traveling on the trip, present the credit card used for purchase, the reference number (displayed after purchase), and valid photo ID. If the credit card is not presented at the counter, a fee will apply. A non-refundable fee also applies for Will Call orders. If the credit card holder is not traveling on the trip, the reference number and valid photo ID are required to pick up tickets. You also can create a password for the traveler to use as ID. A non-refundable gift ticket fee is applied to each Will Call transaction where the credit card holder purchasing tickets is not traveling on that trip. [Emphasis added again, obvs.]
Espero que isso funcione! Boa sorte!
