Gopher State One Call 1-800-252-1166


Gopher State One-Call (GSOC) is the Minnesota Underground Facility Notification Center through which a person can notify operators of underground facilities in the area of proposed excavations and can request that the underground facilities be marked.

Call Before You Dig

Just about anywhere you dig there could be buried underground utilities. Homeowners and contractors can prevent damage to underground utilities and prevent service interruptions by calling Gopher State One-Call at least two working days prior to excavating. GSOC takes information from callers who are digging, processes it in a computer, and notifies underground utility operators that may have utilities in the area. The owners of the utilities will send personnel to mark and locate their utilities within two working days using the APWA Color Code provided:

  • Blue-Water
  • Orange-Communication; Cable TV
  • Red-Electric
  • Sewer-Purple
  • Temporary Survey Markings
  • White Proposed Excavation (Sidewalk Repairs)
  • Yellow-Gas-Oil-Steam

Anyone digging in Minnesota must call before digging if using power equipment. Even when hand digging, you are encouraged to call. The person who is doing the work is responsible for calling GSOC. If the owner contracts with a professional excavator to do the excavation, then the professional excavator is responsible for calling GSOC. To request a locate, you will need to complete the information on the Locate Ticket Form or for several locates use the Multiple Locates Ticket Form. Locate requests can be faxed (800-236-4697) or telephoned (800-252-1166) to Gopher State One-Call.

The service is free. Just call before you dig - it is the law.


Call GSOC at least 2 working days before you dig.
