Pennsylvania Area Codes: Complete Guide to All 15 PA Codes (2026)
All 15 Pennsylvania area codes — 215/267/445, 610/484/835, 717/223, 570/272, 412/878, 724, and 814/582. Coverage maps, overlay pairs, and tips.
Pennsylvania Area Codes: Complete Guide to All 15 PA Codes (2026)
Pennsylvania packs 15 active area codes into a state that has shaped American history since before the Revolution. From Philadelphia's three overlapping codes to the 814 region that was never split in nearly 80 years, the Keystone State's numbering system reflects a complex mix of dense urban centers, sprawling suburbs, and vast rural landscapes.
This guide covers every PA area code — what it serves, when it was created, and why it exists — plus the historical timeline, overlay pairs, and practical tips for calling anywhere in the Commonwealth.
Pennsylvania Area Codes at a Glance
| Code | Overlay(s) | Region |
|---|---|---|
| 215 | 267 / 445 | Philadelphia |
| 610 | 484 / 835 | Eastern PA Suburbs |
| 717 | 223 | South Central PA |
| 570 | 272 | Northeastern PA |
| 412 | 878 | Pittsburgh |
| 724 | 878 | Western PA Suburbs |
| 814 | 582 | NW & Central PA |
All 7 regions use mandatory 10-digit dialing. Area code 878 is unique — it overlays both 412 (Pittsburgh) and 724 (suburbs).
215 / 267 / 445 — Philadelphia
215
267, 445
1947
Eastern (ET)
Area code 215 is one of the original 86 area codes from 1947 and once covered all of eastern Pennsylvania. Today it serves Philadelphia proper and adjacent portions of Bucks and Montgomery counties — a region where both the Declaration of Independence and the U.S. Constitution were debated and signed in the same room at Independence Hall.
The 267 overlay arrived on July 1, 1999, and 445 followed in 2018 — making Philadelphia a rare three-code city. The addition of 445 opened roughly 23 million new phone numbers, projected to last beyond 2050.
Philadelphia First
Philadelphia served as the nation's capital from 1790 to 1800 and is also home to the world's first general-purpose computer — ENIAC, unveiled at the University of Pennsylvania on February 14, 1946. It weighed 30 tons, filled a 30×50-foot room, and could perform 5,000 additions per second. The city also claims America's first zoo (1874), first hospital, first medical school, and first stock exchange.
610 / 484 / 835 — Eastern PA Suburbs & Lehigh Valley
610
484, 835
215 (1994)
~12
The 610 split from 215 on January 8, 1994 — the first area code change in Pennsylvania in 47 years. It serves the Philadelphia suburbs, Lehigh Valley (Allentown, Bethlehem, Easton), Reading, and surrounding counties. The 484 overlay arrived in 1999, and 835 finally activated in September 2022 — making this another three-code region.
The 22-Year Area Code
Area code 835 has the most complex history of any Pennsylvania code. It was first approved in 2000, withdrawn on June 23, 2005 (number pooling reduced demand), re-approved in December 2021, and finally activated on September 2, 2022 — a 22-year journey from approval to first phone call.
The Liberty Bell's Secret Road Trip
When the British occupied Philadelphia in 1777, the 2,080-pound Liberty Bell was secretly smuggled out and hidden beneath the floorboards of the Zion Reformed Church in Allentown (now the 610 region) for nine months. It wasn't returned to Philadelphia until June 1778 after the British retreat. The bell is 70% copper and 25% tin, with traces of gold and silver.
717 / 223 — South Central PA
717
223
1947
Harrisburg, Lancaster, York
Area code 717 is one of Pennsylvania's four originals and covers the state capital corridor — Harrisburg, Lancaster, York, Gettysburg, and Hershey. The 223 overlay arrived on September 26, 2017. Originally, 717 covered the entire central and northeastern portion of the state until the 570 split in 1998.
80 Million Kisses a Day
Hershey, PA produces 80 million Hershey's Kisses every day from a 2.2-million-square-foot plant. Milton Hershey sold his Lancaster Caramel Company for $1 million in 1900 to fund his chocolate empire, then transferred the majority of his fortune to the Milton Hershey School Trust in 1918.
The Bloodiest Three Days
The Battle of Gettysburg (July 1–3, 1863) produced an estimated 51,000 casualties — the most of any Civil War battle. It involved 165,000 soldiers and killed or mortally wounded 11 generals. Pickett's Charge sent 12,500 Confederate soldiers into a devastating assault on Cemetery Ridge.
World's Largest Amish Settlement
Lancaster County is home to the oldest (circa 1760) and largest Amish community on Earth — approximately 45,000 Amish people in 250+ congregations. Pennsylvania overall has over 92,000 Amish residents, the most of any state. The Lancaster Amish population has grown 160% since 2000, roughly doubling every 20 years.
570 / 272 — Northeastern PA
570
272
717 (1998)
~21
The 570 area code split from 717 on December 5, 1998, covering the mountainous northeastern quadrant of Pennsylvania — from Scranton and Wilkes-Barre to the Pocono Mountains and Williamsport. The 272 overlay arrived in October 2013. This region encompasses roughly 21 counties, spanning coal country, the Endless Mountains, and the Pocono resort area.
Major cities include Scranton (population ~77,000), Wilkes-Barre (~44,000), Williamsport (~28,000), and Stroudsburg — gateway to the Delaware Water Gap and the Pocono Mountains resort region that draws millions of visitors annually from New York City and Philadelphia.
412 / 878 — Pittsburgh
412
878
1947
~1.4M
Area code 412 is one of the original 86 area codes and serves Pittsburgh and most of Allegheny County. Locals commonly refer to Pittsburgh as "the 412" as a cultural identity marker. The 724 suburbs split off in February 1998, and the 878 overlay arrived in August 2001 — covering both 412 and 724 territories.
Steel City's Peak
At the peak of World War II, Pittsburgh's mills poured 95 million tons of steel into the war effort. By 1945, Pennsylvania produced more steel than all the Axis powers combined. The industry's collapse between 1980–1986 wiped out 115,000 manufacturing jobs. Pittsburgh reinvented itself around healthcare, technology, and education — today Carnegie Mellon and the University of Pittsburgh anchor the region's economy.
Pittsburgh Firsts
Forbes Field (1909) was the first steel-and-concrete baseball stadium in America — a fitting innovation for the Steel City. Pittsburgh also launched the first commercially successful radio station (KDKA, 1920) and the first public television station (WQED, 1954).
724 / 878 — Western PA Suburbs
724
878
412 (1998)
~14
Area code 724 split from 412 on February 1, 1998, forming a geographic ring around Pittsburgh. It covers the rust belt towns, rolling hills, and small cities extending toward the Ohio and West Virginia borders — including New Castle, Greensburg, Washington, Butler, and Indiana (home of Jimmy Stewart).
The 12-Year Ghost Code
Area code 878 was activated on August 17, 2001, as an overlay for both 412 and 724. But not a single 878 phone number was actually issued until April 2013 — a full 12 years later. Existing number resources in 724 weren't exhausted until then, so the code existed in limbo with zero active subscribers.
814 / 582 — Northwestern & Central PA
814
582
1947
~27
Area code 814 is the only one of Pennsylvania's four original codes that was never geographically split — it still covers its 1947 boundaries across 27 counties, from Lake Erie to the Allegheny Mountains. A grassroots petition in 2010 successfully convinced the PUC to cancel a planned split in favor of the 582 overlay, which finally arrived on May 1, 2021 — making it the last PA region to require 10-digit dialing.
Beaver Stadium
Penn State's Beaver Stadium in State College has an official capacity of 106,572 — the second-largest stadium in the Western Hemisphere. Penn State, founded in 1855 as the Farmers' High School of Pennsylvania, enrolls more than 89,000 students across all campuses and was named the state's first land-grant institution in 1863.
Pennsylvania Area Code Timeline
Pennsylvania receives 4 original area codes
215 (Philadelphia), 412 (Pittsburgh), 717 (central/NE PA), and 814 (NW/central PA) — part of the original 86 North American codes created by AT&T.
610 splits from 215
Philadelphia suburbs, the Lehigh Valley, and Reading separate from Philadelphia proper — the first PA area code change in 47 years.
724 splits from 412; 570 splits from 717
Two splits in one year: Pittsburgh suburbs break from the city, and northeastern PA (Scranton/Poconos) breaks from south-central PA.
484 overlays 610; 267 overlays 215
Pennsylvania's first overlays arrive in eastern PA and Philadelphia. Mandatory 10-digit dialing begins in both regions.
878 overlays both 412 and 724
Unique overlay covering both Pittsburgh proper and surrounding suburbs. However, no 878 numbers are actually issued until April 2013 — a 12-year gap.
272 overlays 570
Northeastern PA (Scranton/Wilkes-Barre/Poconos) receives its overlay.
223 overlays 717
South-central PA (Harrisburg/Lancaster/York) receives its overlay.
445 overlays 215/267
Philadelphia becomes a 3-code city, adding roughly 23 million new numbers — projected to last beyond 2050.
582 overlays 814
The last PA region gets an overlay. 10-digit dialing becomes mandatory statewide for the first time.
835 overlays 610/484
Eastern PA suburbs get a third code — 22 years after 835 was first approved in 2000 (withdrawn in 2005, re-approved 2021).
Tips for Calling Pennsylvania Numbers
10-Digit Dialing Required
Since 2021, all Pennsylvania calls require 10-digit dialing (area code + number). This applies to local calls too — there are no exceptions. Every PA region now has at least two area codes sharing the same geography.
Same Region, Multiple Codes
A Philadelphia number could start with 215, 267, or 445. A Pittsburgh-area number could be 412, 724, or 878. Overlay codes serve the same geographic area — the code doesn't tell you which city or neighborhood someone is in.
All Eastern Time
The entire state is in the Eastern Time Zone. Unlike Indiana or some western states, there are no time zone splits to worry about when calling between PA area codes.
