History of the 318 Area Code
The louisiana 318 area code was introduced in 1957 after Louisiana’s original 504 areas codes could no longer accommodate increasing telephone demand across the state. At the time, 318 covered a much larger territory than it does today. However, rapid population growth and increased telecommunications usage eventually led to further area code splits.
Why a New Overlay Code, 457, Is Being Introduced
Decades of growth, combined with the rising number of devices requiring individual phone numbers, have gradually depleted the pool of available combinations within the 318 area code location. To address this numbering exhaustion, Louisiana regulators approved the introduction of a new overlay code, 457, which will serve the same geographic region as 318 rather than replacing it.
Time Zone
The entire 318 is what area code operates within the Central Time Zone (CT).
This means the region follows:
Businesses communicating with customers across the United States should consider time differences when placing calls to or from the 318 area code region.
Dialing Information
When dialing a 318 number from elsewhere in the country, callers should use the standard format of 1, followed by the areas codes and the seven-digit local number. International callers reaching a number need to add the United States country code before the area code. With the introduction of ten-digit dialing tied to the 457 overlay, residents within the region itself must now include the area code on every local call. This shift mirrors changes already adopted by many other overlay regions across the country.
Industries and Businesses Operating in the Region
The economy across the 318 area code reflects the diversity of northern and central Louisiana, with healthcare, logistics, energy, education, and manufacturing forming the backbone of local employment. Shreveport and Bossier City serve as commercial and healthcare hubs, while Monroe contributes strength in logistics and finance. Alexandria’s central location makes it a natural distribution point for goods moving across the state.
Staying Safe from Spam and Spoofed Calls
As with virtually any active area code, scammers occasionally spoof numbers to make fraudulent calls appear local and trustworthy. Receiving a suspicious call from a number does not necessarily mean the call originated in Louisiana, since modern spoofing technology allows bad actors to display any area code regardless of their actual location. Residents and businesses are encouraged to avoid sharing personal or financial information with unsolicited callers and to report suspicious activity to the Federal Trade Commission.
