Area code 309
Area code 309 is a telephone area code serving the west-central portion of the U.S. state of Illinois. Cities in this area code include Bloomington, Canton, East Moline, East Peoria, Galesburg, Kewanee, Macomb, Minonk, Moline, Morton, Normal, Pekin, Peoria, Rock Island, and Silvis, in addition to many smaller communities within the western part of central Illinois.
The area code was created in 1957, and was one of the first area codes created with "0" as the second digit that didn't serve an entire state. It was the only new area code created in Illinois between the 1947 advent of NANP and the 1989 creation of area code 708.
Area code 309 has telephone numbers assigned for the central office code 988. 988 has been designated nationwide as a dialing code for the National Suicide Prevention Lifeline, which creates a conflict for exchanges that permit seven-digit dialing. This area code is therefore scheduled to transition to ten-digit dialing, mandatory after October 24, 2021.[1] This will also break seven-digit dialing in Illinois; 618 and 708, the only other area codes in the state that have not been overlaid, will also switch to ten-digit dialing for the same reason.
