Dialing Formats: Connecting Within and Beyond 660

To effectively communicate within and outside the 660 area code, you need to understand the correct dialing formats. These formats ensure your calls reach their intended recipients, whether they're across the street or across the country.

• Standard HNPA (Home Numbering Plan Area) Local Calls: Dial all 10 digits of the phone number (e.g., 660-XXX-XXXX). This applies to calls within the 660 area code.
• Standard HNPA Toll Calls: Dial 1 + 10 digits (e.g., 1-660-XXX-XXXX). This is necessary for calls to numbers outside the 660 area code but still within the North American Numbering Plan (NANP).
• Standard FNPA (Foreign Numbering Plan Area) Local Calls: While less common, if you're calling from outside the NANP (e.g., from Europe), you'll likely need to dial the international access code (011 in the US), followed by the country code (1 for the US), and then the 10-digit number.
• Standard FNPA Toll Calls: Similar to FNPA local calls, dial the international access code, country code, and the 10-digit number.
• Operator Assisted Calls: Dial 0 + 10 digits. This connects you with an operator who can assist with specialized calls, such as collect calls or calls to numbers with specific dialing requirements.

Important Note: As of October 24, 2021, ten-digit dialing became mandatory for all calls within area code 660, even for local calls. This change was implemented to accommodate the nationwide designation of 988 as the three-digit dialing code for the National Suicide Prevention Lifeline. This transition ensures that calls to 988 are routed correctly and prevents any conflicts with existing seven-digit numbers.

Regulatory Landscape: Governing Area Code 660

Area code 660, like all area codes within the NANP, operates under the watchful eye of regulatory bodies. These organizations ensure the stability and integrity of the telecommunications system.

• North American Numbering Plan Administrator (NANPA): The NANPA is responsible for overseeing the assignment and management of area codes and other numbering resources within the NANP. They play a crucial role in ensuring the long-term viability of the numbering system. You can find more information on their website (https://www.nationalnanpa.com).
• Federal Communications Commission (FCC): The FCC regulates interstate and international communications by radio, television, wire, satellite, and cable in the United States. They have ultimate authority over telecommunications regulations within the US, including the implementation and enforcement of numbering plan rules. Their website (https://www.fcc.gov) provides a wealth of information on telecommunications regulations.
• Missouri Public Service Commission (MPSC): The MPSC regulates public utilities within the state of Missouri, including telecommunications providers. They work in conjunction with the NANPA and FCC to ensure compliance with state and federal regulations.

Historical Perspective: The Birth of 660

Area code 660 was carved out of the existing area code 816 on October 12, 1997. This split was necessitated by the increasing demand for phone numbers in the region, driven by factors such as population growth, the proliferation of cell phones, and the rise of fax machines and pagers. The creation of 660 ensured that the available numbering resources could keep pace with the growing communication needs of the area. As of September 2022, the projected exhaustion date for area code 660 is the third quarter of 2043, showcasing the effectiveness of this split in providing long-term numbering capacity. This information is crucial for long-term planning and resource allocation within the telecommunications industry.
