Call Before You Dig - OKIE811

About OKIE811

OKIE811 is Oklahoma’s One-Call System that manages all incoming locate requests 24 hours a day, 7 days a week. This is a free service, there is no charge to the excavator or homeowner. 

OKIE811 has over 1,200 member companies that operate underground facilities across Oklahoma. When OKIE811 receives a locate request, they transmit a ticket to each underground facility operator that has services in the area. OKIE811 does not mark the lines; the facility operator sends a locator to the excavation site to mark the approximate location of their underground facilities in the area.

It is the facility owner’s responsibility to communicate where it is safe to dig by marking the area with flags and/or paint and through communications by phone, email or in person.

OKIE811 also provides safety and damage prevention services designed to promote public awareness about the importance of protecting underground facilities. There are six damage prevention councils across each of the states tourism areas in addition to statewide Public Damage Prevention Regional Partner Councils. 


Oklahoma One-Call System, Inc. is a non-profit 501(c)6 corporation, incorporated in the State of Oklahoma in 1979. It was formed for the purpose of preventing damage to underground facilities. Thirty-seven companies originally joined to fund a statewide one-call notification center.

On April 22, 1981, the Governor signed into law an act known as the Oklahoma Underground Facilities Damage Prevention Act. Effective January 1, 1982, the act provided that (1) owners and operators of underground facilities must register, through a notification system, and (2) all excavators must give notice to such underground operators at the notification system prior to excavation.
