IMPORTANT! Emergency and damage tickets cannot be processed through an online ticket submission-you have to place a phone call!  If you are experiencing an emergency or need to report a damage to an underground utility line, please call 911 for medical attention and 911 assistance if needed, and then call us  811  or 800-922-1987  to report the emergency or damage circumstance.  

Before you submit your locate request online, here are a few helpful tips:  

  • According to the Colorado Revised Statue 2022, commonly known as the “Colorado One-Call Law,” all individuals or entities digging in the State of Colorado must contact 811 BEFORE starting any excavation.

  • Whether you’re digging deep or even just a few inches, you must contact Colorado 811 to have public underground utilities marked.

  • All ticket data must be entered in English. Submitting ticket information in any other language will delay the processing of your request.

  • A valid email address must be provided, as it will be used to send important information regarding your locate request, including a ticket confirmation and number.

  • Your request is not valid until an email confirmation has been sent and is received.

  • After receiving your email confirmation, utility companies will respond within two business days (not including the day you receive your confirmation) with either the status of your request or by marking the property.  

  • If public underground utilities are present, their locations will be identified using paint and/or flags. Depending on the utilities present, multiple companies may come out to perform the locates.

  • The party performing the actual excavation (homeowner, contractor, landscaper, etc.) must submit the locate request in their own name.

  • You can check the status of your locate ticket request  using the Ticket Number found in your confirmation email in your Colorado 811 account . 

  • The party performing the actual excavation (home/property owner, contractor, landscaper, etc.) must submit the locate request in their own/company name as an authorized user of the account.

  • Requests to extend public utility marking beyond the boundaries of a single address/property are not permitted.

  • The provided address must be clearly visible on your property.

  • The area must be fully accessible – with no locked gates or animals — for two full business days, not including the day the email confirmation is received.

  • There may be private underground utility lines within your dig area. Private underground lines are owned by the owner of the property and will not be located or marked by 811 as part of this request. It is the responsibility of the excavator to have private utility lines located separately from the Colorado 811 locate request service. There are privately operated locate companies that will mark private underground utility lines on your property. Please Click Here for a list of private locating companies that may be able to assist you. Failing to mark private underground utility lines can cause damage to those lines or lead to serious injury or death.

  • Your request is not valid until an email confirmation.

  • Requests received after 2:00 pm MT may be processed on the next business day.

Positive Response

Positive Response is mandated under Colorado State law, to be provided by the underground facility owner to the excavator requesting the locate request. The facility owner is required to post a Positive Response through the Colorado 811 Positive Response System.

  • If the facility owner has not published to the Colorado 811 system within the expected time-frame, a “Positive Response Re-notification” will be automatically generated at 11:59 p.m. on the locate by date, and every subsequent day until a response is posted.

  • Prior to excavating an excavator must process an “Excavator Re-notification” (formerly known as a Second Notice) if there is no response from the facility owner beyond the due date.

  • Colorado 811 agents do not have a direct link to provide positive response information for any locate request. Please refer to this program only through www.colorado811.org, or call the facility owner directly.

  • Please do not make calls to 8-1-1 for positive response information, if you need assistance please call (877) 318 8188 or email onlineservices@co811.org

You can check response without logging into the system by clicking the ‘Check Ticket Response’ button below and entering the ticket number and phone number or simply login by clicking the ‘Ticket System’ button.
