The finishing touches to the 14-team tournament, to be held in October and November next year, were unveiled at a press conference in Manchester on Thursday morning attended by delegates from the Rugby League International Federation.
Organisers announced in March that Cardiff's Millennium Stadium will host the opening ceremony and a double-header to launch the event and also confirmed venues for the group matches and quarter-finals, but kept the big games under wraps after a delay in finalising contracts.
Co-hosts Wales will get the tournament under way on Saturday, October 26 against qualifiers Italy, followed by England's group A clash with favourites Australia, while the final will be on Saturday, November 30 at Old Trafford, which was also the venue for the last final to be held in England in 2000.
Wembley hosted a double header during the 2011 Four Nations Series and is a regular venue for the Challenge Cup final.
"It's a stunning venue and has hosted some famous Rugby League World Cup games in the past," said RLWC 2013 General Manager Sally Bolton.
"Having two matches back to back will make for a wonderful day of Rugby League with the four top teams going hammer and tongs for a place in the Rugby League World Cup final.
"We know Old Trafford very well too, a venue that always delivers a fantastic Super League Grand Final for us.
"Holding the final there will allow the Rugby League community, the people of the north west and we hope many new fans to witness a fantastic spectacle."
