Only those tickets marked accordingly need to be personalized. It's possible that not every ticket for an event needs to be personalized.
Personalization always takes place after the tickets have been purchased in your MyTicket portal.

In these cases, the purchaser's name will automatically be displayed on the ticket.
The person placing the order is not considered the ticket holder and is irrelevant in this case.
