Fourteen nations are competing in the month-long tournament which starts when England face Australia at Cardiff's Millennium Stadium on 26 October.
England will host 20 of the 28 matches, including the final at Old Trafford in Manchester on 30 November. Host cities include London and Bristol, alongside several venues in the traditional Yorkshire and Lancashire heartlands of the sport.
As well as the opening fixture, Wales also stage matches at the Racecourse Ground in Wrexham and Neath's The Gnoll.
