Area code 318

Area code 318 is a telephone area code that covers northern and central Louisiana.

Area code 318 as of 1999.

It was created in 1957 in a split of Louisiana's original area code, 504. Originally, it covered nearly all of the state west of the Mississippi River, stretching from the Gulf of Mexico north to the border with Arkansas. In 1999, the southern half of the "original" 318, including Lafayette and Lake Charles, became area code 337.

318 had been assigned, temporarily, for San Francisco, because Oakland and San Francisco had separate toll switches, so calls had to be routed accordingly depending on the final destination. As the telephone equipment used at the time handled only three-digit translation, the temporary use of an area code, 318, was required to distinguish between the two Bay Area cities. Area code 318 temporarily was used to specify San Francisco and areas north of the Golden Gate Bridge, while calls with destinations in Oakland or the East Bay used area code 415. When the electromechanical Card-Translator box became available by 1953, translations using six digits were possible; the 318 code no longer was required. The entire San Francisco Bay Area returned to using area code 415; in 1991, 510 split off from 415; by 2015, area code 628 was added as an overlay.

Cities in area code 318
gollark: Mostly they just borrow ridiculous amounts of money.
gollark: In governments they'll just borrow more, yes.
gollark: There have been calls to scrap the TV license and just fund it through taxes. Which would be basically the same functionally.
gollark: No, I mean the "we do worse things so you can't criticise this somewhat bad thing" thing does not make sense. Unless you want to justify this "PBS" on its own merits, in which case do so, or actually don't as I don't really care.
gollark: That's a very stupid argument, but I'm not sure what to call it.
