Area code 314

Area code 314 serves Missouri, including Saint Louis, Ladue and Kirkwood (Central time). It has been in service since January 1, 1947 and shares its area with 557.

Numbers starting with 314 drew 3,108 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 1,079 complaints to the FCC since November 2023. The number on your screen can be faked, so a 314 number proves nothing about where a call came from.

Phone companies holding 314 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 63% 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.
