811, damage prevention, learning and infrastructure — with a source for every operational summary.

01 / Contact the official center
Missouri 811’s current website is missouri-811.org. Call 811 or follow the official ITIC link to submit a request. Prepare the excavation location, depth, type of work, expected start and responsible contacts.
Large routes may need multiple requests. The center’s business rules address county and municipal boundaries and the permitted size of mapped work areas. Use the center’s rules before submitting.
Why you see both “two days” and “three days”: RSMo 319.026 requires at least two and no more than ten working days of advance notice. Section 319.030 starts the two-day period at midnight after receipt. Missouri 811 describes the process as a three-working-day notification period because the request day does not count.
The center states that tickets last 21 consecutive calendar days from the listed start date and time. Request renewal if work continues beyond expiration or marks become unclear. Follow the ticket’s dates; weekends and state holidays affect the notice period.
The law links here open the current sections, including the August 28, 2025 amendments. Historical search results can display older versions.
Open the ticket-number link in the notification email, or use ITIC Search. Enter the ticket number and review “Members Notified” for each utility’s status. Utility members use LTM to document responses; that is separate from excavator status lookup.
If a utility has not responded, use the official No Response process. Follow the center’s directions and scheduled start; a missing status is not a clear-to-dig indication. Keep the response history with the job record.
RSMo 319.015 defines approximate location as the width of the facility plus two feet on each side, with provisions for unusual conditions. State law controls over conflicting CGA guidance. The current notice statute addresses confirming horizontal and vertical position and using hand or soft digging as a best practice when possible.
Section 319.026 requires reporting damage, dislocation or disturbance to the notification center, including damage to protective items. A pipeline contact that releases gas or hazardous liquid requires immediate 911 contact. Do not conceal damage or make unauthorized repairs; consult the statute for its limited sewer-repair exception.
RSMo 319.045 provides civil enforcement authority and equitable remedies. Missouri 811 publishes violation forms and the Attorney General’s One-Call Unit contact: 573-751-2290 or OneCallUnit@ago.mo.gov. Record dates, location, involved parties, ticket information and photographs.
The published forms and contacts were reviewed; no complaint was filed and delivery of the forms or email was not tested.
Use Missouri 811’s official calendar for locator, safety and internet-ticketing sessions. Its website also links an online learning system. Confirm the date, course format and registration directly with the provider. No ReliaTXT workshop is scheduled in this prototype.
Use these sources to research programs and project stages. Award areas, service availability and planned construction are different kinds of evidence. None of them substitutes for utility locating.
Program hub includes award documents and a provider/location/amount table alongside older status updates. Individual contracts, route geometry and construction completion have not been audited.
Current hub exposes the 2027–2031 program, November updates, construction and scoping/design raw data, and an interactive map. A programmed project is not necessarily under construction.
Drinking-water and wastewater funding resources, including revolving-fund loans, planning grants and lead service line funding. Check each program for eligibility and application periods.

Local road-opening permits, city and county right-of-way rules, private-facility coverage and site-specific exceptions.
Complete legal exception review, all administrative rules and a qualified review of safety summaries before production publication.

Sources were reviewed on November 13, 2026. “Verified” means the cited source supports the described record; it does not certify site conditions or all legal obligations.
Current official center website, with homeowner and contractor ticket entry points. Call 811. The older mo1call.com address was not relied on for current guidance.
Use the ticket link in notification emails or ITIC Search, then inspect Members Notified. The center explains notice timing, 21-day ticket life, renewals and no-response requests.
Locator Ticket Management is the utility-member workflow for reviewing locate notices and recording responses. It serves a different role from excavator ticket search.
Notice must be given at least two but no more than ten working days before expected excavation. The current section covers notice contents, remarking, discovery of unmarked facilities and damage reporting.
Explains response duties and the start of the two-working-day period at midnight after receipt. Includes the notification center’s locate-status system and procedures for marking and clarification.
Defines approximate location as facility width plus two feet on each side, with provision for unusual conditions. Missouri law controls if CGA best practices conflict with it.
Authorizes civil enforcement by the Attorney General or a prosecuting attorney. The Attorney General may also seek equitable relief. Consult the section for penalty limits and criteria.
Lists Attorney General One-Call Unit contacts, violation forms and documentation guidance. The published unit phone is 573-751-2290 and email is OneCallUnit@ago.mo.gov.
Official calendar for training and events. Check the provider’s event page for current dates, availability and registration; this site does not sell or reserve seats.
Rules for describing routes, parcels and polygons, crossing county or municipal boundaries, and qualified emergency internet ticketing. Review before preparing a large project request.
