In late 2010, Araujo legally obtained his Ecuadorian citizenship, allowing him to be called up to the Ecuadorian national team. Despite not being called up for a number of pre-tournament friendlies, Araujo was chosen to be part of Ecuador's squad for the 2011 Copa América. He earned his first cap on June 25, 2011 versus Mexico in a friendly game prior to the start of the tournament. He went on to start in all three of Ecuador's group games in the Copa America.
