History of the 309 Area Code
Area Code 309 was created in 1957 when the North American Numbering Plan sought to accommodate growth in telephone service throughout Illinois. Originally, much of the state was covered by fewer area codes, but as communication demands increased, additional codes were introduced to manage the allocation of new numbers.
Over the years, changes have taken place to maintain sufficient numbering resources for expanding populations and businesses. Although there have been no recent splits or overlays directly impacting the 309 region, the state’s telecommunications authority, The Illinois Commerce Commission, located at 527 E. Capitol Ave, Springfield, IL 62701, continuously evaluates the need for area code adjustments. The primary reason for these evaluations is to ensure residents have consistent access to new phone numbers as communities in the 309 service area grow.
How Many People Use the 309 Area Code?
