What is the 618 area code?

The 618 area code covers Southern Illinois, serving major cities such as Belleville, Granite City, and East Alton, as well as counties like Madison, Jackson, and Clair. The 618 area code was introduced as part of the North American Numbering Plan Administrator (NANPA) to address the expanding demand for telephone services in Southern Illinois.

The 618 area code was among the original area codes introduced back in 1947. The 618 phone area code is a single code that covers a wide geographical area, unlike some cities that might need overlays. It is used to add more capacity to the local telephone service.

Businesses and individuals with the 618 area code operate within the Central Time Zone (CT), which observes daylight saving time throughout the state of Illinois and the central part of the U.S. You will find this area code graphically on time maps and numbering plan records maintained by the NANPA.
