802

Area code 802 is an important telephone area code with several key aspects: Exclusive Area Code for Vermont: Area code 802 is unique in that it is the only area code serving the entire state of Vermont. This includes all major cities and towns within the state, such as Burlington, Montpelier, Rutland, and Brattleboro​​. Long-standing Service: This area code has been in service since 1947, making it one of the original area codes established in the North American Numbering Plan (NANP) by AT&T. Its long history reflects the stability and continuity of telecommunication services in Vermont​​​​. Transition to Ten-Digit Dialing: As of October 24, 2021, area code 802 transitioned to ten-digit dialing. This change was partly due to the assignment of telephone numbers for the central office code 988, designated nationwide as a dialing code for the National Suicide Prevention Lifeline in 2020. The adoption of ten-digit dialing is a significant change in the dialing procedures within the area code​​. In summary, area code 802 is integral to the state of Vermont, being its sole area code since 1947. Its coverage of the entire state, including all major cities and towns, and the recent transition to ten-digit dialing, are crucial aspects of its role in Vermont's communication infrastructure.
