Numerous people from all over the country have already been caught out.
The Police Service of Northern Ireland (PSNI) has warned GAA fans to be on alert having received numerous reports of a fraudster offering All-Ireland tickets online in exchange for cash.
The PSNI say that numerous people from all over Ireland have already sent cash to addresses in Belfast without receiving tickets in return ahead of the much-anticipated football decider between Dublin and Mayo on September 17.
In a post on Facebook on Friday morning, the PSNI said that a male claiming to be from Antrim GAA has approached members of the public and is clear when contacted that money in exchange for All-Ireland tickets must be sent in cash.
The addresses monies have been issued to have ranged through all parts of Belfast.
The PSNI have urged anyone who might be suspicious about a call they receive to hang up and phone the organisation that the person is purporting to represent to check their authenticity. Ideally, that call should be made from another telephone so you can be sure the original caller has not remained on the line.
There is already a huge demand for tickets in Dublin and Mayo and amongst neutrals for a second successive final meeting between the counties; Dublin claimed Sam Maguire in 2016, winning by a point in a replay after the sides finished level first time out.
Tickets for both the football and hurling All-Ireland finals are not available for public sale through the usual outlets.
Each county board receives an allocation of tickets for the All-Ireland finals with the competing counties receiving the most significant allocations. These are then filtered down to their clubs and subsequently the club members.
