Call 811 Before You Dig


811 Call before you dig logo

In Pennsylvania, you are required to contact PA One Call, by dialing 8-1-1 at least three business days before you begin any excavation project. When PA One Call receives a call, it will alert the appropriate underground facility owners of your intent to dig. The underground facility owners will identify any underground lines or facilities at your work site.

Everyday excavation can result in consequences that you may not expect resulting in severe injury or death, environmental damage, and costly delays. You can reduce such risks by calling 8-1-1, the call before your dig number.

The Federal Communications Commission (FCC) approved the use of 8-1-1 as the national abbreviated telephone number for commercial and residential consumers to use to provide advanced notice of excavation activities.

In 2006, in keeping with the FCC ruling, the Pennsylvania Public Utility Commission ordered all telephone systems in Pennsylvania to fully implement 8-1-1.
