How does 811 Work?

What is 811?

811 is the free national before-you-dig service. Anyone who plans to dig should contact 811 or go to their state 811 center’s website before digging to request that the approximate location of buried utilities be marked with paint or flags so that you don’t unintentionally dig into an underground utility line.

When do I contact 811?

You should contact 811 or use your state 811 center’s website a few business days before you begin any digging, including common projects like planting trees and shrubs or installing fences and mailboxes.

What info do I need before contacting 811?

You will need to know the address of where you plan to dig, including the county and nearest cross street, as well as the type of project you’re completing and the exact area on the property where you’re planning to dig.

After I contact 811, what do I do?

You need to wait a few days to allow utilities to respond to your request and ensure that all utilities have indeed responded to your request before breaking ground. Once all utilities have marked their buried lines, you should dig carefully around any utility marks and consider relocating projects that are close to buried utilities.
