Key Cities and Communities Served by Area Code 318

The 318 NPA is home to several significant urban centers and numerous smaller towns. Here’s a table highlighting some primary locations:

(Population estimates are approximate and subject to change. Coverage within some border parishes might vary.)

Neighboring Area Codes and Time Zone

The 318 area code borders several other NPAs:

• North: Arkansas area codes 870/327
• East: Mississippi area codes 601/769 and 662
• South: Louisiana area codes 225 (Baton Rouge area) and 337 (Lafayette/Lake Charles area)
• West: Texas area codes 903/430, 936, and 409

The entire region covered by the 318 (and upcoming 457) area code operates within the Central Time Zone (CT). It observes Central Standard Time (CST – UTC-6) in winter and Central Daylight Time (CDT – UTC-5) during Daylight Saving Time (currently active as of April 22, 2025). Businesses communicating across time zones must account for this.

Demographics and Economy within the 318 Area Code Region

The large territory covered by the 318 area code encompasses a diverse mix of urban centers, suburban communities, and rural areas, supported by a varied economic base. Understanding these characteristics is key for businesses seeking to connect effectively.

Population Landscape: Urban and Rural Blend

Northern and Central Louisiana feature a blend of population densities. Major metropolitan areas like Shreveport-Bossier City, Monroe-West Monroe, and Alexandria-Pineville serve as population hubs. These cities offer a mix of demographics typical of Southern urban centers. Outside these hubs, the region includes numerous smaller towns and extensive rural areas, often focused on agriculture and natural resources.

This demographic mix requires businesses to tailor their communication approach. A local 318 number provides a unified point of contact recognized across both urban and rural communities within the region, helping bridge potential geographic divides and building rapport across the diverse populace.

Economic Pillars of Northern Louisiana

While historically influenced by agriculture, timber, and oil and gas, the economy within the 318 NPA has diversified. Key sectors driving the regional economy include:

• Healthcare: Major hospital systems and healthcare providers are significant employers in Shreveport, Monroe, and Alexandria.
• Education: Several universities and colleges, including Louisiana Tech (Ruston), University of Louisiana Monroe (ULM), LSU Shreveport (LSUS), and Northwestern State University (Natchitoches), contribute significantly.
• Manufacturing: Diverse manufacturing activities exist, including aerospace components, wood products, and consumer goods.
• Military: Barksdale Air Force Base near Bossier City is a major economic driver for the Shreveport metro area. Fort Johnson (formerly Fort Polk) near Leesville also impacts the southern parts of the 318 region.
• Logistics & Transportation: Shreveport’s position as a transportation crossroads (I-20, I-49, Red River port) makes logistics important.
• Energy: Oil and gas exploration and production remain relevant, particularly in the Haynesville Shale area.
• Agriculture & Forestry: Still vital in many rural parishes.

Businesses serving or operating within these sectors benefit from using a local 318 calling code. It signals familiarity with the regional economy and facilitates smoother interactions with local suppliers, partners, and customers. Rozper’s reliable VoIP ensures clear communication whether coordinating logistics, providing educational services, or supporting healthcare operations.

Understanding the Upcoming 457 Overlay: What You Need to Know

The sustained demand for telephone numbers within the established 318 area code region has prompted action from regulatory bodies. To ensure a continuing supply of numbers, the Louisiana Public Service Commission (LPSC) has approved an area code overlay, introducing the 457 area code to the same geographic territory. Familiarity with this change is essential for everyone in the region.

Why an Overlay?

High demand from population growth and the proliferation of devices has led to phone number exhaustion in the Detroit region. To resolve this, the 679 area code is being introduced as an overlay, operating within the same geographic area as the existing 313 prefix. This standard relief method provides new numbers while allowing current users to keep their existing ones, avoiding the disruption of geographic splits.

The Implementation Timeline (Mandated by LPSC)

The LPSC has set a specific timeline for this transition:

• February 24, 2025: Start of the six-month “permissive dialing” period. During this time, local calls within the region can be completed using either 7 digits OR 10 digits (Area Code + Number). This allows time for adjustment.
• August 25, 2025: End of permissive dialing. Mandatory 10-digit dialing begins. From this date onward, all local calls within the 318/457 territory must be dialed using the full 10-digit number. 7-digit calls will no longer connect.
• September 25, 2025: Earliest date the new 457 area code can be assigned to new telephone lines or services. Assignment will occur as the remaining 318 numbers are exhausted.

Key Impacts for Users

• Mandatory 10-Digit Dialing: This is the most crucial change affecting daily habits. All local calls require 10 digits from August 25, 2025.
• Existing Numbers Unchanged: Your current phone number, including the 318 area code, will not change.
• New Numbers May Be 457: Eventually, new lines will receive numbers with the 457 prefix, serving the same area.
• Device Reprogramming: Automated dialing systems must be updated to use 10 digits for local calls. This includes security systems, life safety systems, PBXs, fax machines, speed dialers, mobile contact lists, etc. Check with your equipment/service providers.
• Local Calling Areas Remain: The overlay does not change what constitutes a local versus long-distance call for billing purposes.
• Important Numbers: Dialing 911 (Emergency) and 988 (Suicide & Crisis Lifeline) remains unchanged (three digits). Other 3-digit N11 services (211, 511 etc.) also remain the same where available.
