Standard Home Numbering Plan Area (HNPA) Local: 10-digit dialing (Area Code + 7-digit number). This means you must always dial the area code, even for local calls within the 947 area.

Standard Foreign Numbering Plan Area (FNPA) Local: Not applicable within the United States. FNPA refers to calls to countries outside the NANP.
Standard FNPA Toll (International): Follow international dialing procedures, which typically involve an exit code (e.g., 011 in the US), the country code, and the subscriber number.
Standard Operator Assisted: 0 + 10-digit dialing (0 + Area Code + 7-digit number). The "0" prefix connects you to an operator for assistance with calls.

Key takeaway: Always dial all 10 digits (area code + 7-digit number) when making calls within the 947 area code. This practice, known as 10-digit dialing, became mandatory in 2002 to accommodate the growing demand for phone numbers and the implementation of the 947 overlay.

Telecom Regulations and the FCC

The Federal Communications Commission (FCC) plays a vital role in regulating area codes and telecommunications within the United States. They are responsible for managing the NANP and ensuring its continued functionality. You can find detailed information about area code regulations, numbering plan administration, and other telecommunications matters on the FCC's official website. The FCC's oversight ensures fair competition among telecommunications providers and efficient use of numbering resources. As technology evolves and communication needs change, the FCC adapts its regulations to maintain a robust and reliable telecommunications infrastructure. For example, the FCC's mandate for 10-digit dialing in areas like 947 is a direct response to the increasing demand for phone numbers and the need to conserve numbering resources.
