The Arsenal star has been a regular part of the squad since making his international debut in November 2011 and could pick up his 50th cap in one of Les Bleus' upcoming friendlies against Wales or Germany.
Koscielny was particularly prominent in France's qualification for the World Cup, playing 90 minutes in eight of their 10 matches.
But he accepts that all good things must come to an end, pointing out that he will be 33 shortly after the end of the World Cup.
"There is an end to everything," he told reporters ahead of Saturday's (AEDT) meeting with Wales.
"After the World Cup I will be almost 33 years old and it will be time to leave.
"I have six months left in the France team to blossom and make the most of these memories, as my wife would say."
