Phone numbers with the 667 area code prefix originate from the eastern half of the U.S. state of Maryland, covering the Baltimore metropolitan area and the Eastern Shore.
Area code 667 is part of an overlay system that serves the same geographic region in Maryland. This numbering plan area is served by three area codes: 410, 443, and 667. Area code 410 was the initial code for the region, introduced on October 6, 1991, following a split from area code 301. Area code 443 was subsequently overlaid onto the 410 territory on July 1, 1997. The 667 area code was implemented as a third overlay code on March 24, 2012, due to continued number exhaustion. With this overlay system, ten-digit dialing is required for all local calls within this numbering plan area.
Area code 667 is a General Purpose Code which was placed in service on January 1, 1947.
