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]
