History of the 730 Area Code
The 730 area code was established as an overlay to the 618 area code due to increased demand for new telephone numbers in southern Illinois. The 618 area code, one of the state’s original codes established in 1947, was nearing number exhaustion. In response, NANPA, in cooperation with the Illinois Commerce Commission, implemented the 730 overlay.
Timeline:
- 2020: NANPA and Illinois Commerce Commission propose the 730 overlay due to projected number exhaustion.
- July 7, 2023: New area code 730 officially goes into service as an overlay for 618.
- Overlay approach: Existing numbers keep the 618 code; new numbers may be assigned 730. Ten-digit dialing becomes mandatory for all local calls in the region.
How Many People Use the 730 Area Code?
Area code 730 is newly assigned as an overlay to the 618 region, so most residents and businesses still use 618 numbers. As the available blocks of 618 numbers are depleted, new phone lines (including cell phones and landlines) will receive the 730 prefix. Southern Illinois, encompassing the 730/618 area, is home to over 1.2 million people, though the number of active 730 numbers is growing as the transition continues.
Is the 730 Area Code Toll-Free?
No, area code 730 is not a toll-free area code. It is a standard geographic code for southern Illinois. Calls to or from area code 730 are subject to standard rates as determined by your calling plan and provider.
Toll-free U.S. area codes include: 800, 833, 844, 855, 866, 877, and 888.
