Area Code 931: Comprehensive Guide to Clarksville, Tennessee

This guide provides a deep dive into the intricacies of Area Code 931, focusing on its relevance for developers building applications that interact with telephony systems and businesses operating within the Middle Tennessee region. We'll cover geographic coverage, dialing patterns, carrier services, regulatory considerations, and best practices for ensuring seamless communication within this area code.

Area Code 931

Area Code 931 is a telephone area code within the North American Numbering Plan (NANP), specifically serving Middle Tennessee.

You'll find it encompasses a significant area beyond Clarksville, including cities like Columbia, Cookeville, Tullahoma, and Manchester. This split was necessary due to the rapid growth and increasing demand for phone numbers in the mid-1990s, a trend that continues to this day.

Geographic Coverage in Detail

Understanding the geographic distribution within Area Code 931 is essential for location-based services and targeted marketing campaigns. Let's break down the key areas:

Clarksville, Tennessee: The Heart of 931

Clarksville, the fifth-largest city in Tennessee, serves as the focal point of Area Code 931. Located in Montgomery County, its geographic coordinates are approximately 36.52977 latitude and -87.35945 longitude. As of 2022, Clarksville boasted a population of nearly 168,000, with a median age of 30.1. [4] This demographic information is valuable for developers tailoring applications to the local user base.

Expanding Beyond Clarksville: Surrounding Cities and Towns

Area Code 931 extends its reach to numerous other counties and municipalities across Middle Tennessee. This expansive coverage makes it a critical consideration for businesses planning their communication strategies and developers designing applications with location-aware features. You should consider the diverse needs of users across this region when developing your solutions.

Dialing Patterns and Regulatory Compliance

Correct dialing is crucial for successful call routing and ensuring your applications comply with telecommunications regulations. Here's a breakdown of the dialing patterns for Area Code 931:

• Local Calls (within 931): You can typically dial the seven-digit number directly (7D). However, with the increasing prevalence of area code overlays, ten-digit dialing (1 + area code + 7D) is becoming increasingly common and is often recommended for ensuring call completion.
• Toll Calls (outside 931): Dial 1 + area code + 7D (One plus Ten Digits). This applies to calls originating from within Area Code 931 to numbers outside the area code.
• Operator Assistance: Dial 0 + area code + 7D (Zero plus Ten Digits).

Important Note: While 7-digit dialing might still function in some instances, adhering to 10-digit dialing is a best practice to ensure call completion and future-proof your applications. This is especially important as number availability within area code 931 becomes increasingly limited. [2]

Due to the region's growth, number availability within Area Code 931 can be a concern. Businesses are advised to secure numbers well in advance to avoid disruptions. Developers should incorporate number availability checks into their applications to provide users with realistic options.

Additional Considerations for Developers
