Colorado 811 and one-call center
Anyone planning excavation in Colorado should contact 811 before digging. Find Locators is not a one-call center and cannot create, update, extend, or resolve a locate request — use the official center below for the process, requirements, wait times, and tolerance-zone rules that apply.
Colorado 811 (Utility Notification Center of Colorado)
- Phone: 811 (damage reporting 800-922-1987; office 303-232-1991)

What to do after the ticket
Review the response from each notified facility operator, resolve incomplete or unmarked responses through the official Colorado process, and assess whether privately owned facilities may remain. A private locator does not replace the official notification.
