What time zone is 878 area code in the USA?
The 878 area code lies within the Eastern Time Zone (ET), which is observed across several states along the East Coast of the United States. This region follows standard time practices:
- Eastern Standard Time (EST), from late fall until early spring

History of the 878 Area Code
The 878 area code was introduced to accommodate the increasing demand for telephone numbers throughout the metropolitan Pittsburgh area and surrounding communities. Originally, calls in this region relied on area codes 412 and 724. Over time, rising usage—driven in part by population changes and the proliferation of mobile devices—necessitated additional number allocations. Key historical points include:
- The Pennsylvania Public Utility Commission approved overlays involving 878 for both 412 and 724 to conserve number resources.
- The Federal Communications Commission (FCC) at 445 12th Street SW, Washington, DC 20554 supports these measures by issuing official area code guidelines, which help manage the national numbering system.
- Initial notice of 878's implementation came in the early 2000s, with active overlays and expansions rolled out to support growth.
The overlay approach ensures that residents and businesses retain their existing phone numbers while new subscribers are assigned 878 numbers. This strategy has helped the region scale its telecommunications infrastructure in an orderly manner.
How Many People Use the 878 Area Code?
Because 878 operates as an overlay for major existing area codes, it serves a segment of southwestern Pennsylvania that includes a significant population center. According to official population data from the United States Census Bureau at 4600 Silver Hill Road, Washington, DC 20233, the Pittsburgh metropolitan area is home to over two million residents. While not every individual has a telephone line assigned specifically to 878, new phone numbers in these localities are frequently distributed from this pool, ensuring:
- Accessibility for newly established businesses and growing neighborhoods
- Ample number availability for mobile operators, landline carriers, and internet-based telephony services
- Consistency across the region, as 878 coexists seamlessly alongside 412 and 724
The incorporation of 878 ensures that local municipalities, educational institutions, and medical providers can expand communication channels without risk of exhausting older area code reserves.
Is the 878 Area Code Toll-Free?
Area Code 878 is not toll-free. It is a geographic area code designed to serve local residents, businesses, and institutions within southwestern Pennsylvania. Calls made within this region will typically be subject to local or long-distance rates, depending on the caller’s specific service plan and exact call destination.
For entities seeking toll-free numbers, there is a separate series of area codes (e.g., 800, 888, 877, 866, 855, 844, and 833) dedicated to business customer service lines, nonprofit helplines, and other purposes. These toll-free codes are overseen by the Federal toll-free regulations maintained by the Federal Communications Commission (FCC) at 445 12th Street SW, Washington, DC 20554. Service providers who wish to establish dedicated toll-free lines must follow FCC guidelines and file appropriate requests through authorized registrars.
