What service does Missouri 811 provide?
Before Missouri 811 was founded, excavators were not only responsible for excavating, but they were also responsible for identifying each utility owner and calling them all individually to request that they locate their underground utilities. This process was very time-consuming and inefficient for excavators and utility owners alike. As a result, injuries and damages continued to increase, thus forcing the government to create the Missouri Underground Facility Safety and Damage Prevention Act RSMO 319. This Act provided a set of laws and regulations that standardized the digging process and paved the way for Missouri One Call Systems (later rebranded as Missouri 811 in 2023) to be established in 1986.
Missouri 811 is a not-for-profit organization that serves as the central point of contact for locating all public underground utilities throughout the state. Under the RSMO 319 laws, everyone in the state of Missouri is required to contact Missouri 811 to request a FREE underground utility locate before starting any digging project. Once Missouri 811 is contacted, it bears the responsibility of notifying all the public utility owners in the vicinity of the dig site so they can mark their underground utilities.

By serving as the central point of contact, Missouri 811 helps facilitate public underground locates for both homeowners and professional excavators.
How Does Utility Marking Work?
Utility marking is a complex process that involves several steps, ensuring accuracy and timeliness in locating underground utilities. Here’s a closer look at how it works:
Notification: The process begins when a homeowner or excavator contacts Missouri 811, at least three working days in advance, as stipulated by state law, to allow sufficient time for the utility marking process. This notification is typically done online or by phone.
Information Gathering: Missouri 811 collects detailed information about the proposed dig site so we can contact the appropriate utility owners. The more accurate the information, the better Missouri 811 and the public utilities can support the excavator or homeowner.
The following information will be requested by Missouri 811 when submitting a locate request:
Excavator Information:
Location Information:
Public Utility Company Notification: Once the dig site details are collected, Missouri 811 notifies the relevant public utility companies that have infrastructure in the area so they can mark their underground utilities. These can include water, gas, electricity, telecommunications, and sewage services.
Locating the Utilities: Utility companies then dispatch locators to the dig site who use a variety of tools and technologies to identify and mark the locations of their public underground utilities. The tools used may include electromagnetic equipment or signal transmitters.
Color-Coded Markings: The locators mark the ground with color-coded paint or flags, with each color representing a different type of utility. The markings provide a visual guide for areas to avoid when excavating.
Confirm the Marks: All public utilities are required to mark their underground utilities within three working days of being notified by Missouri 811 unless an extension has been granted. Homeowners and excavators are required to verify that all public utilities have responded to their locate request. This can be done by verifying the status provided by Missouri 811 via email.
Dig With CARE: It is important to remember that locating an underground utility is not an exact science. Each color code mark should be considered an “approximate locate” and extreme caution should be taken if excavation within 24” of either side of the markings is required. This area is considered to be the tolerance zone, and hand digging is highly recommended.
