Area code 730

Area code 730 serves Illinois, including Centralia, Herrin and Belleville (Central time). It has been in service since July 7, 2023 and shares its area with 618.

Numbers starting with 730 drew 98 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 32 complaints to the FCC since November 2023. The number on your screen can be faked, so a 730 number proves nothing about where a call came from.

Phone companies holding 730 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 100% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
