Fans are being warned only those with genuine tickets will get past the tight security at the tournament.
Ryder Cup bosses have launched a website to help combat ticket fraud.
As all tournament tickets are non-transferable and can be traced back to the original purchaser, the site confirms the validity of genuine tickets purchased from an official source.
However, customers with tickets that have been fraudulently sold on or purchased from an unauthorised seller will be warned their tickets are not valid, potentially resulting in them being turned away at the gates.
Richard Hills, Europe’s Ryder Cup director, said: “Protecting golf fans, our travel customers and hospitality guests against ticket fraud is a responsibility we take very seriously.
“The Ryder Cup Ticket Check website gives consumers peace of mind that their tickets are valid and they will be granted access to Gleneagles.”
More than 250,000 people are expected to attend The 2014 Ryder Cup at Gleneagles, which tees off on September 23.
