Call New York 811, by dialing 811, to verify that we received your request. If we have received your request, and no lines have been marked on your property, do not assume it is safe to begin digging. All of the notified member companies who have lines in the area must provide you with “positive response,” or give the all clear, before digging can commence. If you have not heard from the notified member companies, call New York 811. Have your ticket number handy.
