The European champions extended an outstanding 32- match unbeaten run when they opened their campaign in South Africa with a 5-0 rout of New Zealand on Sunday.
But that win was also their 13th successive victory.
Three more points against the Asian champions would mean Spain equalled the longest consecutive winning run in the record books.
That mark currently stands at 14 wins and is shared by Australia (1996-97), Brazil (1997) and France (2003- 04). Spain's win over New Zealand was their 13th successive victory, while a 34th game unbeaten would move them within one match of the world record mark of 35 games established by Brazil between 1993 and 1996.
Iraq midfielder Nashat Akram said an opportunity to share the field with the big names of Spain was a dream for the players.
"We are so proud to be in this competition and to get a chance to be on the pitch with the stars.
"It will be a very tough game, they have so many quality players. We'll do our best," he said.
