Missouri 811 (formerly Missouri One Call System) serves as the single point of contact for all public underground facilities located throughout the state 24 hours a day, 7 days a week, 365 days a year. Once Missouri 811 is notified of a dig site by the excavator (homeowner or professional), Missouri 811 notifies all the public underground facility owners in the vicinity of the dig site so they can locate and mark their own facilities to prevent damage or disruption. This service is funded by its members and is free to anyone digging in Missouri.
