What is the french area code for 0417?

There is no area code 0557 in France according to this site... http://wwp.greenwichmeantime.com/time-zone/Europe/european-union/france/telephone.htm Although a quick google search with "tel 05.57" brings up lots of numbers in the Gironde region around Bordeaux. http://www.google.fr/search?q="tel+05.57"

However, 0556 is the most common code for Bordeaux and 0559 serves Biarritz and Pau.
