What is 811? 811 is the national phone number designated by the Federal Communications Commission that connects professionals and homeowners who plan to dig with their local one-call center.
How does 811 work? When you call 811 in the U.S.A., he/she is connected to the local one-call center, where a representative collects information about the caller's planned dig site. The one-call center then communicates the information to the appropriate utility companies, which send professional utility locating technicians to identify and mark the approximate location of lines within a few days of the phone call. Once the lines have been marked, the caller may dig safely around the marks.
