We are unable to help you verify the validity of tickets that have been purchased outside of Ticketmaster Danmark. For example if your tickets have been purchased from dba.dk, Viagogo, friends, relatives etc. Therefore we advice you to always purchase your tickets from the official ticketing company. Then you get the tickets for the correct price, and the validity is ensured. You can read more about ticket fraud here.
I have purhased tickets from a non-official ticketing provider. Can you check if it's valid?
