Call before you dig. It's the law!
Find your One-Call number here.

The Utility Notification Center is the one-call agency dedicated to safeguarding citizens and construction personnel who work around utilities, as well as safeguarding the underground infrastructure of pipes, mains and lines which bring utilities to your community.

Calling before beginning any excavation prevents damage to underground facilities, service interruptions, and bodily injury.

The Utility Notification Center is open 24 hours a day, every day, and accepts calls from contractors, homeowners, or anyone planning to dig in Oregon, Washington, Montana and Hawaii. Calling before you dig ensures that any publicly owned underground facilities will be marked according to the APWA color code so that you can dig safely.

For more details about why you should call, what you need to know before calling, and what happens after you call, see the Excavator frequently asked questions (FAQ), and the laws regarding calling before you dig.

Locate requests are accepted over the phone, through a fax-a-locate program, or through the ITIC program. If you need to process a locate request, or need additional information about locates, you may contact the Utility Notification Center at any time.
