United States
In the U.S., 811 is the national one-call number. Dialing 8-1-1 will connect you directly to your local one-call center. For more information about the national one-call number, visit call811.com.
Most states require excavators to notify a local one-call center of any proposed digging or soil-disturbing activity at least two, sometimes three, business days before beginning any excavation. This is a free service.
When you call 811, the operator will redirect your call to your local state one-call center and request the location where you plan on doing work. A locator will come to mark the locations where you can dig safely within a few days.
Canada
The recently launched Click Before You Dig website, at www.clickbeforeyoudig.com, represents Canada’s first national “one-window” approach for requesting the locations of buried utilities prior to ground disturbance. A minimum of two full working days is required in advance for all utilities to be located and marked via the ClickBeforeYouDig.com process.
