From Wikipedia, the free encyclopedia

Area code 318 is a telephone area code that covers the central and northern parts of Louisiana. The area code was split off in 1957 from the original area code 504, which had previously covered the entire state.

Originally, 318 stretched from the Gulf of Mexico north to the border with Arkansas. However the southern portion of the "original" 318 area code split off into area code 337 in 1999/2000.

Also From 1951 to 1953, 318 was temporarily used for San Francisco because Oakland and San Francisco each had their own separate toll-switches, so calls had to be routed accordingly depending on the final destination. As the telephone equipment used at the time could only handle 3-digit translation, the temporary use of area code 318 was required in order to distinguish between the two areas. Area code 318 was temporarily used to specify San Francisco and areas north of the Golden Gate, while calls with destinations in Oakland and the East Bay continued to use area code 415. When the electromechanical Card-Translator box became available sometime during 1952-53, 6-digit translation became possible and the use of area code 318 was no longer required. Area code 318 was reclaimed for future use and the entire San Francisco Bay Area returned to using area code 415.
