A huge number of Ireland fans pledged their support for the team at www.bethedifference.ie to be in with a chance of having their names printed on the back of an Irish player's jersey for the England game.
Each of the 22 squad members will wear a custom designed jersey on Saturday with hundreds of names of genuine Irish rugby fans printed on their squad number.
The names of the fans who made the cut are viewable here.
On the Be The Difference website, you can add your name to the supporters list and it will be included in the 'Book of Support' which will be presented to the squad on the eve of the England game.
You can add your name to the book here.
Ireland captain Brian O'Driscoll said: "It's great to see O2's Be The Difference campaign being embraced by the Irish public.
"I took delivery of a couple of posters made up of signatures and we obviously have the names of thousands of supporters on our jerseys on Saturday.
"It's a brilliant idea and one that reinforces for every player the close bond between those who wear it and those who support it. It's a huge honour and a responsibility we all take very seriously."
