# West Virginia Area Code 681
The 681 area code is an overlay area code that serves West Virginia, specifically covering the same geographic region as the original 304 area code. Established in 2001, the 681 area code was created to address the growing demand for telephone numbers in the state as telecommunications usage expanded. When an overlay area code is implemented, both the new and existing area codes serve the same territory, meaning residents and businesses in West Virginia may have either a 304 or 681 area code regardless of their physical location. This system allows telephone companies to distribute numbers more efficiently without requiring customers to change their existing numbers or area codes.
The North American Numbering Plan (NANP) is the standardized system that designates area codes like 681 throughout North America, including the United States, Canada, and several Caribbean nations. The NANP organizes telephone numbers into a hierarchical structure, with three-digit area codes serving as the first component of a ten-digit phone number. When a region exhausts its available numbers within an area code, telecommunications regulators can implement overlay codes like 681 to ensure continued service availability. This systematic approach to number allocation helps maintain order across the continent's vast telephone network and ensures that all phone numbers follow a consistent format, making it easier for calls to be routed correctly across different carriers and regions.
