One of the most potentially hazardous situations in residential areas, industrial plants and construction sites is accidental contact with underground electric power lines, natural gas lines, communication lines and other utility services.

To ensure you're working safely, call an underground line locating service. There’s no charge for the service, and the call is free. Calling before you dig can not only save you money from a damage claim, it can also save your life.

All you have to remember is 811. That’s the FCC-designated number to call before any digging project. 811 will connect you to the local One Call Center, which will notify area utilities to mark the approximate location of underground lines. Check out more information on 811.

Most protection services require at least a 48-hour notice; some may be longer. Call 811 or the numbers below for the best information for your state.
