North Louisiana, not New Orleans
People in Shreveport and Monroe can tell a 504 number from one of their own.
318 has covered the northern half of the state since 1957, and it carries a different identity from the south. It is the code of the Red River in Shreveport, the Ouachita in Monroe and the crossroads town of Alexandria. Calling from 318 shows you are part of that world. It gives customers one less reason to screen your call.
