Area Codes


Until 1997, Pennsylvania had four area codes – 814 (northwest), 412 (Pittsburgh area), 717 (central) and 215 (Philadelphia). With the increased use of cell phones and consumers purchasing additional lines in their homes, the demand for additional telephone lines exploded. This demand put the four area codes in Pennsylvania in jeopardy.

Since then, five more were added from 1997 through 2000: 724 in greater Pittsburgh, 570 in Northeastern Pa., and 610, 484 and 267 in Southeastern Pa. In 2001, another code was activated in the greater Pittsburgh area (878). Over the succeeding years, conservation measures implemented by the Commission and the FCC delayed additional area exhaustions until 2013 when the 272 area code was added to portions of the state. 

  • The 272 area code overlay went into service October 21, 2013, in the 570 Number Planning Area (NPA).
  • The 223 area code overlay went into service September 26, 2017, in the 717 NPA.
  • The 445 area code overlay went into service March 3, 2018, in the 215/267 NPA.

Thousands-Block Pooling

Mandatory thousands-block pooling began in June 2010. The industry, NANPA and the Commission monitor the area codes to determine if or when relief will be needed. Pooling uses telephone numbers more efficiently while ultimately delaying the need to add new area codes in the future. 


Conserving Area Codes

Over the past several years, the PUC instituted several numbering conservation efforts to slow the proliferation of area codes in Pennsylvania, including pooling and NXX code and thousands-block reclamation.
