Taylor Swift is set to play two gigs in Ireland this summer.
The singer has already sold out the first of her Croke Park gigs, with tickets for the second date going on sale Friday.
Those who bought Taylor’s album Reputation on her site were offered a presale link.
In light of the demand for tickets, Ticketmaster has issued a warning to fans looking to go to the gig.
The ticket site warned fans about buying access codes from others.
“BE SAFE OUT THERE #Swifties! Do not buy #TaylorSwiftTix access codes – they are not transferable.”
It added: “Never buy tickets from unofficial sellers. We can only guarantee tickets bought on Ticketmaster.”
They added photos with warning notices to the message.
One elaborated on issues regarding sharing codes.
The ticket site also warned against unofficial sellers.
They then reminded followers that sometimes fans chose to sell their tickets and that this is not illegal.
Tickets for Taylor’s second Croke Park gig (June 16th) go on sale on Friday, October 8th at 9 am.
