Area code 947

Area code 947 serves Michigan, including Ortonville, Clarkston and Farmington (Eastern time). It has been in service since September 7, 2002 and shares its area with 248.

Numbers starting with 947 drew 324 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 135 complaints to the FCC since November 2023. The number on your screen can be faked, so a 947 number proves nothing about where a call came from.

Phone companies holding 947 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 100% 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.
