Area code 667

Area code 667 serves Maryland, including Baltimore, Pikesville and Aberdeen (Eastern time). It has been in service since March 24, 2012 and shares its area with 410 and 443.

Numbers starting with 667 drew 801 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 624 complaints to the FCC since November 2023. The number on your screen can be faked, so a 667 number proves nothing about where a call came from.

Phone companies holding 667 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.
