Area code 320

Area code 320 serves Minnesota, including Saint Cloud, Alexandria and Willmar (Central time). It has been in service since March 17, 1996.

Numbers starting with 320 drew 747 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 387 complaints to the FCC since November 2023. The number on your screen can be faked, so a 320 number proves nothing about where a call came from.

Phone companies holding 320 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 72% 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.
