Information required for requesting locate facilities:

When you call, please be prepared to give an Iowa One Call operator the following information:

Within a city:

• A street address or block and lot numbers, or both, of the proposed area of excavation.
• The name and address of the excavator.
• The excavator's telephone number.
• The type and extent of the proposed excavation.
• Whether the discharge of explosives is anticipated.
• The date and time when excavation is scheduled to begin.
• Approximate location of the excavation on the property.
• If known, the name of the housing development and property owner.

Outside a city:

• The name of the county, township, range, and section.
• The name and address of the excavator.
• The excavator's telephone number.
• The type and extent of the proposed excavation.
• Whether the discharge of explosives is anticipated.
• The date and time when excavation is scheduled to begin.
• Approximate location of the excavation on the property.
• If known, the quarter section, E911 address and global positioning system coordinate, name of the property owner, name of housing development with street address or block and lot numbers, or both.

Each locate request processed is assigned an eight-digit serial number by the computer. This number contains all the information about your call. It is important to write this number down and keep it with your records. Iowa One Call retains this information for six years.

* If you need additional assistance, call your local County Recorder's office.

Location Accuracy is Important

A common mistake in utility locates is not properly identifying your excavation/digging location. Prior to making a request, be sure to determine whether your excavation site is located in a village/city or a township. Often, your mailing address may include the name of the nearest village/city, when you are actually located in a township.
