Fans looking to buy tickets for Euro 2016 through illegal websites are warned that they may be refused entry.
Based on the rules of the European football body Uefa, ticket holders are likely to present ID to get into the grounds and the name must match with that on the ticket.
Alex Neill, Which? director of policy and campaigns, said: "If you haven't bought your ticket directly from an official source there is no guarantee that you'll be able to get into the game and you could be left thousands of pounds out of pocket,"
Meanwhile, Eufa released a statement Uefa saying: "No tickets for individual football fans are being distributed via agencies or brokers, and Uefa encourages fans not to be lured into deals with touts, who not only demand exorbitant prices but are often not even in possession of the tickets they purport to have for sale."
Simon Blackburn, chair of the LGA's Safer and Stronger Communities Board, added: "Social media sites now account for nearly half of all ticket scams and they need to do more to help prevent people being conned paying for tickets on their sites.
"People should be very wary of ticket offers for 'sold out' events as these situations are exploited by criminals,"
