About

Iowa law states that if you are excavating, including digging, you must call Iowa One Call at least 48 hours in advance to minimize the risk of damaging any underground facilities (electric, gas, communications/television, water, and sewer). Saturdays, Sundays and legal holidays do not count toward the required 48-hour notice. The one-call system provides two easy ways to obtain locating and marking of underground facilities. It’s fast, it’s free, it’s the law.

Call or Click

The national 811 three-digit dialing system allows easy access to Iowa One Call. You can simply dial 811 to be connected to a live person at the call center. (If you are near the Iowa border or out of the state, dial 1-800-292-8989). During this five-minute phone call, the call center representative will gather information about your excavation that will be transmitted to the facility operator and locators. 

You may also create a ticket on our website. Generating a ticket online allows you to create precise drawings and descriptions of your proposed excavation. The NextGen system offers detailed mapping tools to easily communicate the extent of your project with the locators.

From the time the notice is transmitted, the facility operators have 48 hours (excluding Saturdays, Sundays and holidays) to locate their infrastructure with spray paint and flags. Note: Iowa One Call is neither a utility nor a locating service. Iowa One Call owns no facilities and does not locate underground facilities.

The Iowa One Call system processes over 540,000 tickets and coordinates more than 2.7 million locate requests per year in communities throughout Iowa. 

History and Background

Iowa One Call (IOC) was started in 1980 by Northwestern Bell (CenturyLink, until recently Qwest) and Iowa Illinois Gas & Electric (now MidAmerican Energy Co.) as a means to maintain the integrity of their utility systems. The service at that time was voluntary but since January 1, 1993, all owners and operators of underground facilities are required by state law to join IOC. Membership now exceeds 1,400.

IOC provides contractors/excavators, homeowners, and others who plan to disturb the earth, with a single toll-free number to call, and online ticket entry, for the locating and marking of these underground facilities.

IOC is not a utility. IOC owns no facilities and does not locate underground facilities. IOC receives requests for underground facility locates from excavators (persons and legal entities) planning projects that will entail excavating. IOC processes all requests for locates and then transmits the requests to the IOC member companies (all owners/operators of underground facilities are required to register with the Iowa One Call system) who own, operate or maintain underground facilities within the area of proposed excavation. Each underground facility operator is then responsible for locating and marking their own facilities. 

The service provided by Iowa One Call, and the locating and marking of underground facilities by underground facility operators, is free of charge to excavators. The IOC system is paid in full by IOC member companies.

The board of directors is elected by the membership of the organization and does not receive compensation for serving. An IOC annual report is filed with the Iowa Utility Board and is available for review. IOC meetings and records are subject to the State’s open meetings and records law. A certified audit is conducted yearly.
