Area code 573

Area code 573 serves Missouri, including Columbia, Jefferson City and Cape Girardeau (Central time). It has been in service since January 7, 1996 and shares its area with 235.

Numbers starting with 573 drew 2,015 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 499 complaints to the FCC since November 2023. The number on your screen can be faked, so a 573 number proves nothing about where a call came from.

Phone companies holding 573 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 88% 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.
