The attacker was named as Omar Ismail Mostefai, a 29-year-old French citizen of Algerian origin. Six people close to him were reportedly taken into custody on Saturday morning.
Police also say they have found a black Seat car they suspect was used to attack two restaurants.
France is in three days of mourning.
A special service for the families of the victims and survivors will be held at Paris’s Notre Dame Cathedral later on Sunday.
Friday’s attacks, claimed by Islamic State (IS) militants, hit a concert hall, a major stadium, restaurants and bars in the French capital.
Prime Minister Manuel Valls has said France will continue with air strikes against IS in Syria, and described the group as a very well-organised enemy.
President Francois Hollande has cancelled his plans to attend the G20 in Turkey and is holding meetings with various political leaders to discuss the crisis.
Mostefai was reportedly identified after investigators found a severed finger at the scene of the worst atrocity, the Bataclan concert hall where more than 80 people died.

We are glad that terrorists and those who helped them would be severely punished. This is the Western justice system at its best by punishing the individuals concerned rather than group punishment by creating a hostile environment against all Muslims.
We need to win over moderate and patriotic Muslims to defeat the extremists in every country of the world, with sizeable Muslim population, to put our Global village on the right course.
