About Missouri One Call System (MOCS)

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.
