Area Code 309
In 1940, Bell Laboratories and AT&T laid the foundation of an area code system. Though this area code system was introduced in 1940, yet it came into effect in 1947. This area coding system was known as the NANP or North American Numbering Plan. In 1947, states as well as provinces that were related to only one area code were assigned three digit numbers as area codes with zero as the middle digit. States as well as provinces that were associated with more than a single area code were assigned three digit numbers as area codes having one as their middle digit.
309 is the area code for telephone numbers serving the major cities of Canton, Bloomington, Macomb, Galesburg, Normal, Moline, Peoria Pekin, and Rock Island. In addition to this, this takes into consideration the innumerable communities in the western segment of central Illinois.
