267 Area Code: Philadelphia, Pennsylvania

Pennsylvania's 267 area code is an overlay sharing geography with the long-running 215 across Philadelphia, Bucks County, and Montgomery County. Philadelphia anchors the directory's records here. The city sits at the confluence of the Delaware and Schuylkill rivers, organized around the famously dense colonial-era grid and a substantial concentration of healthcare, higher education, and financial services employment. The 267 designation has been filling with allocations since the late 1990s, when Philadelphia's number demand began outpacing what 215 alone could support.

In records the directory has compiled for 267 numbers, other Pennsylvania cities — Allentown, Erie, Harrisburg, and Lancaster — recur frequently. None of those are inside the 267 footprint. The pattern reflects standard public-record dynamics across Pennsylvania. The directory currently documents 515 distinct prefixes within 267 in detail, a working subset of the prefix population the code carries.

Philadelphia's home values come in close to the US median, with median household income running below the national figure. The city's median age sits a few years under the US reading, and population places Philadelphia among the larger cities in the country. The 267 footprint shares those demographics with 215 because both codes serve Philadelphia and the surrounding eastern Pennsylvania counties in overlapping form, and the broader region's economic and demographic profile reflects the city's role as a major commercial, healthcare, and educational center for the Mid-Atlantic.
