Area code 267 is an overlay for the Philadelphia region, sharing coverage with area code 215 in southeastern Pennsylvania. Introduced in 1999 due to increasing demand, it covers the same area, including the city of Philadelphia and nearby communities like Bucks and Montgomery counties. This region is known for its deep historical roots, major universities, vibrant neighborhoods, and evolving tech and medical industries. Ten-digit dialing is required throughout the area. Though 215 retains legacy prestige, 267 has become widely accepted and integrated into the identity of Greater Philadelphia, symbolizing modern growth and urban dynamism.
