Area code 612

Area code 612 serves Minnesota, including Twin Cities and Cambridge (Central time). It has been in service since January 1, 1947.

Numbers starting with 612 drew 904 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 567 complaints to the FCC since November 2023. The number on your screen can be faked, so a 612 number proves nothing about where a call came from.

Phone companies holding 612 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 56% 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.
