History of the 618 Area Code
Originally assigned in 1947, Area Code 618 is one of the first established numbering plan areas in Illinois. It has served as the primary code for the lower portion of Illinois for decades, maintaining consistent coverage despite changes elsewhere in the state. However, over time, increasing demand for new residential and business lines necessitated periodic reviews by regulatory bodies. Major milestones include:
- 1947: Initial creation of Area Code 618 under the North American Numbering Plan.
- Late 20th Century: Substantial population growth and the expansion of telephone services prompted regulatory assessments and proposals for potential splits or overlays.
- 2020s: Overlays were introduced in certain regions of Illinois to accommodate the increasing number of mobile devices, landlines, and business communication lines.

How Many People Use the 618 Area Code?
Area Code 618 currently provides service to a population that exceeds one million residents across a broad swath of southern Illinois. Recent estimates suggest that the majority of households in the region maintain at least one active line tied to the 618 area code, with many businesses registering additional lines to handle customer service and internal communications. The continued demand for newer technologies, including mobile data plans and internet-based calling, has contributed to the expansion of assigned numbers within 618.
Numerical allocations of area codes and their potential exhaust timelines fall under the oversight of the Federal Communications Commission (FCC), which focuses on “telecommunications oversight.” The FCC is located at * 45 L Street NE, Washington, DC 20554 *.
Is the 618 Area Code Toll-Free?
The 618 area code is strictly classified as a geographic code within the state of Illinois. It is not designated as toll-free. Phone users dialing 618 numbers typically incur usage charges based on their calling plans and distance, where applicable. Key points to remember include:
- Calls within the same area code may still be subject to local or long-distance charges, depending on the service provider.
- 618 does not fall under any national toll-free prefixes (e.g., 800, 888, 877).
- Businesses or individuals seeking toll-free numbers must acquire them under recognized toll-free codes regulated by both federal and state agencies.
Government bodies advise consumers to check with service providers regarding specific rate structures and calling rules. Any additional clarifications on pricing limitations or phone policies may be obtained through official channels, such as your provider’s customer service department or relevant publications from the Illinois Commerce Commission.
