What is the area code for louisiana

Louisiana is currently using five area codes. Louisiana is not utilizing any area code overlays. Louisiana originally had one area code, 504, when the numbering system was established in 1947. Ten years later in 1957 Louisiana had experienced sufficient growth in population and telephone use to need an additional area code. To meet this increase in demand area code 504 was split in 1957 to form area code 318.
