Base Map Update Changes


Iowa One-Call is pleased to inform you that we have updated and improved the geographic base map for all Iowa counties. If you have coverage near or crossing county boundaries, please take a close look to verify that you will have property coverage with the new county boundaries.


The new map data will be installed on November 16, 2016. Please compare your existing coverage area against the new map before November 1, 2016 to ensure your facilities will remain properly protected and to give yourself adequate time to make any necessary changes prior to the installation of the new map data.

Whether you're trenching in a field, planting a tree or digging a foundation, Iowa law requires everyone to locate underground utilities before digging. First, notify Iowa One Call to begin the process, then wait 48 hours (excluding Saturday, Sunday and legal holidays) BEFORE any digging begins. Call or click before you dig. This service is FREE and it's the law.



It's Holiday Season!

Any person planning to engage in projects that will entail digging, excavating, or disturbing the earth, are required to provide notice to IOC at least 48 hours prior to the commencement of digging/excavation, excluding Saturdays, Sundays, and legal holidays.




Iowa One Call is pleased to announce that homeowners and one time excavators can now use the newly streamlined system to submit their requests online. Effective March 1, 2013, a version of on-line ticketing designed specifically with the occasional user of Iowa One Call in mind will be available.


On-line ticket entry has been used in Iowa for several years. Because professional excavators as a group were the biggest users of Iowa One Call, the software used primarily designed with them in mind.


Several modifications to the program have made it much more user-friendly for the homeowner or other one time excavator. Getting started is as simple as clicking on a link and entering your email address. The user will be sent a link by return email to verify their request. Once they click on the accompanying link, they will be transferred to the ticket entry web site and be able to get started.
