The North Carolina One-Call Center, a non-profit organization funded by our members, takes excavation information from contractors, utilities and homeowners, anyone engaged in excavation activities, and transmits this information to our members. The member utility owner or their representatives will mark the location of the underground facilities within 48 hours of your call, free of charge. The members range from utilities to universities, from municipalities to home owner associations. Each caller is informed of the members that will be notified. The excavator needs to call directly, any utility owner or their representative that is not a member to physically mark the utility lines.
