My experience is from Ticket Operations on the venue side with Ticketmaster in place as the seller.<br><br>
The original purchaser can present ID and the credit card used to make the purchase at the Box Office to have the tickets reprinted. For very large shows at a venue working with TM, TM representatives will often be on hand to personally deal with the strangest issues. Otherwise, a CSR at the window should be able to reprint with no problem.<br><br>
As far as ticket reselling and stolen or duplicate tickets, the benefit of the doubt always goes to the original purchaser of the tickets.<br><br>
In the case of counterfeits: If you show up and a ticket taker gets a "STOP" across their scanner and you are denied access to the building because your tickets are already inside, the matter will be addressed by venue guest services staff. As far as the venue is concerned, he original purchaser of the tickets, if present, will be permitted entrance. Any further actions (ticket resale fraud) should be taken up with the police.<br><br>
Ticketmaster runs its own resale site called Tickets Now and other ticket sellers do the same. This is one way to guarantee that your tickets are for real. The venue and TM take no responsibility for ensuring the legitimacy of tickets sold on the second hand market.<br><br>
If you've never spent the evening in the box office of a 20,000+ seat venue on the night of a sold out concert, you have missed a show in and of itself.
