Call Before You Dig

Call Before You Dig

Do you know who to call before digging or excavating on your property?

You need to call the Oregon Utility Notification Center (OUNC). The OUNC is the Oregon state agency that administers Oregon’s excavation laws and the statewide toll free “One-Call” number: 1-800-332-2344 (2DIG), or just 811.

The Governor-appointed Board of Directors serves to administer the OUNC, and also caries out a variety of public relations and educational programs, such as “Dig Safely” and “Call Before You Dig”. The “One-Call Center” is located in Portland and is staffed by about 50 operators. The Center is available to process locate requests seven days a week, 24 hours a day.

The One-Call Center provides a free service to home owners, contractors and other excavators, informing them of any buried facilities in the area where they are planning to dig. To request locates for proposed excavation, you can reach the One-Call Center at 1-800-332-2344.

Oregon law requires that anyone digging in private property or any public right of way to call the One Call Center prior to digging. Everyone, contractor and homeowner alike, must call two business days before digging. After the call is received, the One-Call Center will notify all affected Operators. The Operators then have two business days to locate and accurately mark their underground facilities using color-coded paint. For more information, view the Call Before You Dig handout from the State website.
