Colorado 811 File Attachments Deployment & Functionality

WHAT: Colorado 811 is deploying File Attachments Functionality on Friday May 22, 2020.

WHEN: May 22, 2020

WHY: Colorado State law requires that Colorado 811 provide a method by which homeowners, professional excavators and members can exchange file attachments through the notification association (Colorado 811).

WHAT THIS MEANS TO YOU: This software upgrade will not immediately impact you; however, you will notice newly available options related to file attachments in the CO811 applications that you use every day. Starting on Friday, May 22, 2020, homeowners, professional excavators, and members can use CO811 software applications to exchange file attachments when requesting a notification (ticket) and when posting a positive response. There will be a grace period of seven-months for members to adjust to the new file attachment feature set. Effective: 01/01/2021, File Attachments/Positive Response will be available and mandated for all members completing this two-factor requirement under law. Read more on the law at
