Tennessee 811  is the underground utility notification center for Tennessee.


Using our service, excavators are able to notify operators of underground facilities of proposed excavations, to request that the underground facilities be marked before they dig.


One easy phone call to 811  starts the process of having your underground utility lines marked for free!

 Buried utilities could exist just about anywhere you dig. Homeowners and contractors can prevent damage to underground utilities and prevent service interruptions by calling TN811 at least three working days prior to excavating.


It's free, easy, and it's the law!


 TN811 receives information from callers who are digging, processes it using a sophisticated software mapping system, and notifies underground utility operators that may have utilities in the area. The owners of the utilities then send personnel to mark and locate their utilities.


 Tennessee 811 accepts locate requests twenty-four hours a day, seven days a week.


Always call 811 before you dig!

 Give it a try, call 811 to protect yourself and your property against underground utility damage and liability.

 Find out where underground utility lines are buried before you dig. Anyone planning to dig in Tennessee must call before actual work begins and you will need to provide information about the work site when you call 811.
