History of Area Code 447

Area code 447 was established on March 27, 2021, as an overlay for area code 217. The Illinois Commerce Commission approved the new code after 217 neared exhaustion. The overlay means both area codes now serve the same geographic region.

Area code 217 is one of the original North American area codes created in 1947. For decades, 217 alone served this large Illinois region. The addition of 447 reflected growth in demand for phone numbers from mobile phones, businesses, and other devices.
