There will be increased security at Paris' Stade de France for Six Nations matches following the attacks on the French capital in November.
The stadium was targeted during a friendly between France and Germany on 13 November.
France start the Six Nations with a match against Italy on 6 February.
"There will be very strict controls for fans and everyone else entering the Stade de France," the French Rugby Federation (FFR) said.
"The FFR therefore invites all supporters to get to the stadium early, gates will open two hours before kick-off.
"The national police and security officers have planned a number of checkpoints around the stadium to cut down on queues at the gates where controls will be increased."
