Area code 847

Area code 847 serves Illinois, including Northbrook, Roselle and Arlington Heights (Central time). It has been in service since January 20, 1996 and shares its area with 224.

Numbers starting with 847 drew 1,384 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 490 complaints to the FCC since November 2023. The number on your screen can be faked, so an 847 number proves nothing about where a call came from.

Phone companies holding 847 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 52% 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.
