Pennsylvania, one of the original thirteen colonies, has a rich history reflected in its telecommunications landscape. The state has been served by several area codes since the North American Numbering Plan was established in 1947. Initially, Pennsylvania was assigned area code 215, which covered the southeastern part of the state, including cities like Philadelphia. Over the decades, population growth and the proliferation of telecommunications services led to the introduction of additional area codes.
As of 2023, Pennsylvania utilizes a total of 11 area codes, with 215, 267, and 445 serving southeastern Pennsylvania; 412, 724, and 878 covering the southwestern region; 610 and 484 for the Lehigh Valley and surrounding areas; and 570 and 272 for northeastern Pennsylvania. The most recent addition, area code 272, was implemented in 2018 to relieve congestion in the 570 area code.
With an estimated population of approximately 13 million, Pennsylvania is the fifth most populous state in the U.S. This diverse population, combined with a mixture of urban, suburban, and rural areas, creates a unique telecommunications environment. Major cities like Pittsburgh and Philadelphia are central to the state’s infrastructure, while rural regions often rely on different service provision strategies.
Pennsylvania's area codes reflect not only its historical growth and urbanization but also ongoing changes in communication technologies, addressing the demands of a modern, interconnected society. The state’s legislative frameworks and regulatory bodies continue to adapt to ensure effective service provision across all demographics.

Pennsylvania has 11 area codes (484, 610, 814, 272, 570, 412, 878, 717, 215, 267, 724). These area codes are split between cities or states, so if you want to call to Pennsylvania, you need to know exactly where you would like to call.
The first 3 digits to call Pennsylvania may vary depending on where you want to call to, being one or the other depending on the region or city. Take a look at our listing above to find out which area code you need.
Calling Pennsylvania from another state in the United States is considered a long-distance call. Here’s how to make the call: First, dial the area code for Pennsylvania. Each state, and sometimes specific cities within a state, has unique area codes. Then, enter the 7-digit phone number of the person or business you’re trying to reach. If you’re calling from a landline, check with your provider, as long-distance charges may apply. However, most mobile carriers in the U.S. offer nationwide calling without additional fees. Alternatively, you can use VoIP or internet-based calling apps, like Skype, Zoom, or WhatsApp, to bypass traditional long-distance charges. The number you want to reach should look like this: 1-(AreaCode)-111-2222.
When making calls within the United States, dialing +1 depends on several factors. On most modern mobile phones, carriers automatically recognize the country code when calling within the U.S., so dialing +1 is usually not required; you can simply enter the area code followed by the phone number, such as 213-555-1234. If you’re using a landline, dialing 1 (the U.S. country code) before the area code and phone number is often necessary for long-distance calls; for example, calling from one state to another may require dialing 1-213-555-1234. When calling the U.S. from another country, dialing +1 is necessary, so a call from abroad would be formatted as +1-213-555-1234. VoIP and internet-based calling platforms, like Skype and WhatsApp, generally handle country codes automatically, making it unnecessary to dial +1 manually for U.S. numbers.
