Pennsylvania business phone guide

Pennsylvania's business economy

Pennsylvania had 13.1 million residents in the Census Bureau's July 2024 estimate, up 0.6% from April 2020. The U.S. population grew 2.6% over the same period. County Business Patterns counted 307,065 business establishments in the state in 2023 with 5,713,846 mid-March employees and $363.9 billion in annual payroll. The average establishment has 18.6 employees. 51.5% of establishments with employees had fewer than five people. The three largest sectors by establishments are retail trade (40,238), health care and social assistance (39,602), and other services (except public administration) (37,221).

How Pennsylvania's businesses compare

Pennsylvania has 23.5 business establishments per 1,000 residents, 4.5% below the U.S. figure of 24.6. Establishments average 18.6 employees against 16.7 nationally, and payroll per employee is $63,690 (6.8% below the U.S. $68,342). 51.5% of establishments with employees have fewer than five people (U.S.: 55.5%), while 6.2% have 50 or more. Because a handful of large employers lift the average, the share of very small establishments says more about who buys a small-business phone system.

Which Pennsylvania area code to pick

Every Pennsylvania area code requires ten-digit dialing for local calls, according to NANPA's dialing-plan data, so customers always see and dial the full number. In overlays (215/267/445, 484/610/835, 223/717, 582/814, 724/878, and 272/570), the codes share one territory, so a new number may come from any code in the overlay. A business that serves one city usually takes a number in that city's dominant code; one that covers a region can hold up to 3 local numbers on Callata's plan.

368 Pennsylvania cities and towns have their own local-number page. The most populous are Allentown (484/610), Reading (484/610), Erie (582/814), and Bethlehem (484/610).
