Single Address Request Web Ticket Entry Check Ticket ResponseWeb Ticket Entry
Web Ticket Entry (WTE) allows any authorized user to process Colorado 811 locate ticket requests online with full mapping capabilities. WTE is strongly recommended for all professional excavators to process their own tickets.
Notice: Colorado 811 will transition from our legacy Norfield/ Newtin system to the new Exactix ticketing platform in January 2026. For more information about Colorado 811’s new Exactix Ticketing System, please click here.
Web Ticket Entry WTE User Policy Abbreviation ListSingle Address Requests
Single address or residential and private property requests allow you to submit a single-address locate request online, 24/7. It's simple, fast and free.
Emergency and damage tickets cannot be processed through this platform. If you are experiencing an emergency or damage, please call 911 if appropriate and then call 811 to report the emergency or damage.
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 request, including a ticket confirmation and number.
The party performing the actual excavation (homeowner, contractor, landscaper, etc.) must submit the locate request in their own name.
This platform is for single-address locate requests only. If you need to process point-to-point or intersection requests, please use Web Ticket Entry or call 811.
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 the 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.
Your request is not valid until an email confirmation is received.
After receiving your email confirmation, utility companies will respond within two business days (not including the day you receive your confirmation) with the 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.
Check the status of your request using the ticket number found in your confirmation email at https://newtin.co811.org/responsedisplay/ .
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 Renotification” will be automatically generated at 11:59 p.m. on the locate by date, and every subsequent day until a response is posted.
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.

Web Ticket EntryExactix
Colorado 811 is committed to being one of the leaders of damage prevention efforts in Colorado by providing efficient access to a One-Call Notification Service to foster effective communication between the professional excavators, underground utility companies, and the public.

We are currently in the development phase of this project and will continue to share updates as the transition progresses.
As we move towards this important system upgrade, supporting our members and all other users remains a top priority. To ensure a smooth and successful transition, Colorado 811 will offer a series of informational sessions and comprehensive user training. In addition, we’ve launched a brand-new Knowledge Base, packed with FAQs and helpful resources to answer your questions and provide you with additional information every step of the way.

Excavator Training on Colorado 811 Exactix Ticketing System
Every current WTE user is required to take one of the Exactix training sessions and MUST pass a competency exam to gain access to the new Colorado 811 Exactix Ticket System.
These sessions are designed to train existing CO811 Web Ticket Entry (WTE) professional users – this training is not recommended for brand new users of the Colorado 811 ticket system or home/property owners. You must have an active WTE user account already set up to attend these training sessions. New users are encouraged to be on the lookout for future training post the Exactix Ticket System launch, since new account creation will not be available until post-launch date.
Training options for current WTE users and future new users include online on demand training sessions and live in-person training sessions to equip users with the Exactix system knowledge to submit locate ticket requests effectively and efficiently.
