Area code 734

Area code 734 serves Michigan, including Ann Arbor, Livonia and Wayne (Eastern time). It has been in service since December 13, 1997 and shares its area with 679.

Numbers starting with 734 drew 1,732 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 541 complaints to the FCC since November 2023. The number on your screen can be faked, so a 734 number proves nothing about where a call came from.

Phone companies holding 734 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 71% 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.
