History of the 318 Area Code

The 318 area code was established in 1957 as part of the original North American Numbering Plan. It was created to serve the northern and central regions of Louisiana. Over the years, the area code has undergone changes to accommodate the growing demand for telephone numbers. In 1999, a split occurred, resulting in the creation of area code 337 to serve the southwestern part of the state. This change was necessary to ensure adequate numbering resources for the region. For more historical details, visit the North American Numbering Plan Administrator (NANPA).
