Who We Are


The Missouri Underground Facility Safety and Damage Prevention statute (RSMo Chapter 319) provides for a notification center to be used by participating utilities to receive locate requests. Missouri One Call System, Inc. (MOCS), operating as a non-profit Missouri corporation, is such a notification center providing a single-point of contact for notification to its members through a state wide toll-free telephone number operating 24 hours a day, seven days a week. MOCS was established in 1986 and currently is providing statewide services to utilities and excavators to comply with the law. This law applies to any person excavating in the state of Missouri.

MOCS was established as a means to protect underground facilities and assist excavators and utilities in complying with Missouri’s statute and OSHA Rules 1926.651. By using the service that MOCS provides, the general public’s safety and the environment also are protected.

Safe digging is everyone’s responsibility.

Missouri law requires that any person making or beginning any excavation must notify the Missouri One Call System (MOCS) at least 3, but not more than 10 working days prior to beginning excavation, except in the case of an emergency.

Call 1-800-DIG-RITE (344-7483), 811 or click above to place a locate request.  You will need the address of where you plan to dig, what type of work you will be doing and the type of equipment that will be used.  Based on the address of the dig site the affected utility companies will be notified.  They will send a locator to mark the affected underground lines.
