Area codes 215, 267, and 445

Area codes 215, 267, and 445 are the North American telephone area codes for the City of Philadelphia as well as Bucks and Montgomery counties in the Commonwealth of Pennsylvania. The original area code is 215, which was established in 1947, while 267 and 445 are overlay codes for the same numbering plan area (NPA).

In 1947, when AT&T established the North American Numbering Plan, the original area code 215 included the entire southeastern part of the Commonwealth, from the Delaware border to the Lehigh Valley. Pennsylvania was divided into four numbering plan areas, the second most in the Bell System after New York State, a status shared with Illinois, Ohio, and Texas.

On January 8, 1994, the western and northern portions of the original 215 territory, i.e. Philadelphia's western suburbs, most of Berks County, and the Lehigh Valley, changed to area code 610, while Philadelphia and its northern suburbs retained 215. However, three central office codes were moved from 215 to 717, namely 267 in Denver, 484 in Adamstown and 445 in Terre Hill, with 215-267 becoming 717-336 because 717-267 was already in use. These exchanges were all served by non-Bell telephone companies which sought to consolidate their eastern Pennsylvania customers into one area code, and were to change area code anyway (would have moved to 610). The codes 267, 445, and 484 were later used for overlay area codes (484 in 610, and the other two in 215).

This was intended as a long-term solution, but within two years 215 was close to exhaustion due to the rapid growth of the Philadelphia area and the proliferation of cell phones and pagers. For relief, area code 267 was established as an overlay on the 215 numbering plan area on July 1, 1997. Local calls across the Delaware/Pennsylvania border were changed to ten-digit dialing.

Area code 445 was first proposed in July 2000 as an overlay code on numbering plan areas 215 and 267.[1] However, these plans were delayed and then rescinded in 2003 by the Pennsylvania Public Utility Commission.[2] The need for new phone numbers in area codes 215/267 was delayed until 2018. Area code 445 was activated as an additional overlay code on February 3, 2018.[3]

Counties served
Philadelphia was located in the original numbering plan area 215; 267 was added in 1997 and 445 in 2018.

The 215/267/445 area codes serve all or part of five counties in Pennsylvania.[4]
