The city will be in the first in the country to implement the service for all public high schools, according to Sveriges Television.
The measure is just one more way to combat the growing levels of absenteeism in area high schools.
Last year, around 12,000 Swedish high school students skipped classes.
In Gothenburg alone there were 800 students and the number of reports of truancy has increased by 70 percent in two years.
According to the schools code, since 2006 parents are to be contacted when their children have an unauthorized absence from high school.
