, 484 in Adamstown and 445 in Terre Hill, with 215-267 becoming 717-336 because 717-267 was already in use. These exchanges were originally slated to move into 610, but were served by non-Bell telephone companies which sought to consolidate their eastern Pennsylvania customers into one area code. 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. However, these plans were delayed and then rescinded in 2003 by the

. 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.

The most recent NANP exhaust projections do not list an exhaust date for the 215/267/445 territory, meaning that Philadelphia may not need a fourth area code until beyond 2050.April 2020 NANP exhaust analysis
