Aaron Hughes said he reversed his decision to retire from international football because he missed playing for his country.
Hughes took the decision after holding discussions with new Northern Ireland boss Michael O'Neill.
The Fulham defender spoke to O'Neill last week and he will be in the squad announced on Monday for the friendly against Norway at Windsor Park on 29 February.
"After speaking with the new manager, Michael O'Neill, and also Billy McKinlay, who I'm obviously close to at Fulham, I feel I would like to once again return, and try to help us qualify for the next World Cup," added Hughes.
"I am proud to represent my country and it is my aim to contribute as much as I possibly can for the upcoming matches."
