Area code 235

Area code 235 serves Missouri, including Birch Tree, Cape Girardeau and Columbia (Central time). It has been in service since March 24, 2024 and shares its area with 573.

Numbers starting with 235 drew 59 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 17 complaints to the FCC since November 2023. The number on your screen can be faked, so a 235 number proves nothing about where a call came from.

Phone companies holding 235 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 98% 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.
