Established in 1983, Tennessee 811 serves as the statewide official one-call center. Tennessee 811 does not mark lines but functions as a communications link between our member utilities and anyone excavating.
Tennessee’s Underground Utility Damage Prevention Act (TCA 65-31-101) requires everyone who digs to contact Tennessee 811 at least three (3) working days’ notice before starting a project. Tennessee 811 processes the notification of proposed excavation and notifies our member utilities, or their contract locators, to mark their underground facilities prior to the excavation.
This free service helps prevent damage incidents which can result in millions of dollars in property damage, the interruption of utility service, personal injuries, and even loss of life.
Tennessee 811 is a non-profit governed by a Board of Directors.
