811 is the national Call Before You Dig number. It helps protect pipelines and utility lines from excavation damage.
Each state manages the Call Before You Dig process. When you call 811, the request goes to your state’s 811 center for intake. The center sends the details to the affected utility companies to mark their facilities. The state sets how many days the affected utility have to mark their facilities. You must wait until this time has passed before starting any excavation work.
Details
When excavation work is needed on Xfinity or customer property, Xfinity or the designated contractor must contact 811 to request for the utilities to mark their facility in the area where work will be done. Excavation work can’t start until the required number of days set by each state have passed to allow the utilities to mark their facilities.
You must call 811 for any job that requires excavation, even small projects. Each state has their own Call Before You Dig laws, which may vary. Failing to follow the state 811 requirements may result in fines and repair costs.
