About Us

JULIE, Inc. (JULIE) is a not-for-profit corporation dedicated to keeping Illinois safe and connected. JULIE stands for Joint Utility Locating Information for Excavators.

Across the country, every few minutes an underground utility line is damaged because someone decided to dig without contacting a one-call center such as JULIE first. This is a free service. JULIE neither owns nor marks any underground utility lines.

View the JULIE Fact Sheet for more information.

In Illinois, safe digging starts when you call JULIE at 8-1-1 (the nationwide 3-digit number to have your underground utility lines marked at no cost) or go online to enter a locate request.  If you are digging within the City of Chicago’s Corporate Limits, you can reach 811 Chicago by calling  312-744-7000.


In the early 1970s, four major Illinois utility companies realized that when burying their own facilities, they were inadvertently damaging the lines of other companies.   In August 1974, Illinois Bell Telephone, Natural Gas Pipeline, Northern Illinois Gas and Commonwealth Edison founded JULIE as a means of preventing injuries and reducing damages to underground facilities.  JULIE began operations in Will County and expanded its coverage in December 1980 to include all of Illinois with the exception of the City of Chicago. In1992, we built our state-of-the-art facility at our current location serving as a model for similar organizations across the nation.

In 1976, the JULIE system was accepted by the Illinois Commerce Commission as compliance with the one-call notification section of General Order 185.  The Illinois General Assembly enacted the Illinois Underground Utility Facilities Damage Prevention Act on January 1, 1991 with changes to the Act in 2002, 2003, 2004, 2006 and 2009.
