Fans have been warned they may be refused entry to next year's World Cup if they do not buy tickets through the official channels when they go on sale.
Reports suggest criminal gangs are plotting to buy tickets and sell them on at inflated prices.
England Rugby 2015's Joanna Manning-Cooper said: "Our ticketing terms and conditions are strict.
"We reserve the right to refuse entry if tickets have not been purchased through official channels."
England Rugby 2015 failed to persuade the government to make touting of Rugby World Cup tickets illegal.
The ticket agency Ticketmaster has introduced measures to combat touts, who will use sophisticated software to flood its website with ticket applications for high-demand games.
Ahead of tickets going on sale at 10am on Friday, communications director Manning-Cooper added: "We are doing everything we can to make sure tickets get into the hands of fans who want to come to the tournament, and not to touts who simply want to sell them on at a profit."
