Starting January 29, 2026, Colorado 811 (CO811) will require Facility Owner/Operator Members to upload supporting documentation as part of their Positive Response.

Please note, a Positive Response is not considered complete until a file attachment is submitted.

  • Daily renotifications will be sent if supporting documentation is missing, except in the following situations: 
Attachments are not required for these Positive Response Codes:

  • 013 – No Conflict, Privately Owned Utility on Property (Contact Private Utility Owner for Locate) 
  • 025 – Locate Not Completed without Excavator Agreement 

     

Attachments are also not required for the following ticket types: 

  • Damage 
  • Emergency 
  • Cancel 
When do renotifications and charges apply? 
  • Automatic Positive Response Renotification ticket deliveries and associated charges will begin January 29, 2026, if no file attachment is provided as required.
