History

Tennessee has seen changes in its area codes to accommodate the growing need for phone numbers. Originally served by area code 901, the state introduced 615 for Middle Tennessee and later added codes like 423, 865, and 731 as demand increased. The most recent change was the introduction of the 629 overlay to provide more numbers in the 615 region. These adaptations illustrate the state's efforts to maintain efficient telecommunications services for its residents and businesses.
