What is 318 area code?

The 318 area code is located in the state of Louisiana and covers cities such as Shreveport, Monroe, and Alexandria. It was created in 1999 as an overlay to the existing 318 area code to provide more phone number options due to increasing demand. The 318 area code serves a large portion of Northern Louisiana and is predominantly used for landline phone numbers, although some cell phone numbers are also assigned to this area code. The 318 area code is operated by the North American Numbering Plan Administration (NANPA) and is part of the geographic numbering plan area (NPA) code.
