What is the Mississippi 811 (MS811) Positive Response Information System (PRIS)?

The MS811 PRIS is an automated information system operated and maintained by MS811. Begin January 1st, 2021, the Mississippi Excavation law will require that utility owners/operators report through PRIS the status of the work performed, within 2 working days. Please see House Bill 1334 for supporting documentation. Excavators can review the information submitted to determine the status of their request prior to excavation. PRIS can improve communication between the utility and excavator. It can also prevent delays in work and prevent unnecessary “No Response” tickets.


How can I check on the status of a locate request?

We encourage all excavators to review the response information for their tickets prior to excavation or before calling to report a “No Response”. Response information can be viewed using any of the following methods.

  • MS811 Web Portal
    • You do not need an account to view ticket response information
    • Click on “Find Tickets”
    • Enter your ticket number
    • Click Search
    • Current responses submitted will be listed under the “Response Status As of” section of the ticket.
  • MS811 Mobile App
    • Available for download on iTunes and Google Play
    • You do not need an account to view ticket response information
    • Click on
    • Select “Find Tickets”
    • Enter your ticket number
    • Click Search
    • Current responses submitted will be listed under the “Responses” section of the ticket.
  • Ticket Confirmation Email
    • MS811 will transmit a confirmation email to the excavator, immediately after a locate request is processed, if a valid email address is provided.
    • The ticket number contains a hyperlink that automatically open the ticket in the Web Portal.
    • Current responses submitted will be listed under the “Response Status As of” section of the ticket.
  • Ticket Response Status Notification Email
    • MS811 will transmit a status notification email to the excavator, if all utilities have responded, or on the legal ‘locate by’ date and time.
    • The notification is only sent if a valid email address was provided on the locate request.
    • The notice includes response status information submitted to the MS811 PRIS, by participating utility owner/operators, as well as a hyperlink that will open the ticket in the Web Portal.

You can use the ticket number hyperlinks any time you want to see if additional responses have been submitted after receiving the notices.


What should I know when reviewing the response status information?

The following are the different responses you may see when reviewing the status of your ticket, as well as what you should know about them. If the utility owner/operator has multiple utility types, there may be a separate response submitted for each utility.

  • Located: Facilities marked
    • The utility has marked their lines in the area specified on the locate request, however, if you encounter or see evidence that the utility still has unmarked underground utility lines, cease excavation, and contact MS811 immediately.
  • Clear: No conflict
    • The utility does not have any underground utilities in the area specified on the locate request, however, if you encounter or see evidence that the utility still has unmarked underground utility lines, cease excavation, and contact MS811 immediately.
  • On Site Meeting Request: Utility representative is requesting to be on site during excavation
    • The utility should have contacted you to set up the meeting. If they have not done so you should contact them yourself directly.
  • Locate Delayed: Locate Delayed
    • The only reason locate delayed should be selected, is when lines can only be located by excavation. Please see the Mississippi Excavation Law section 77-13-9c for supporting documentation.
    • If the utility company must excavate to locate their lines, by law, they have an additional 2 working days to get their lines located. Once the lines have been successfully located the utility is required to update the status to “Located”.
    • If a locate is delayed for any other reason the utility is not in compliance with the law and you may file an violation against them using the Alleged Violation Reporting (AVR) tool.
  • Located To Meter Only: Private property beyond meter not located
    • Most utility companies will only mark up to their meter or the property line if there is no meter. The landowner will be responsible for locating any underground utilities beyond that point.
  • No Response: Utility did not submit response
    • The utility did not submit a response by the required date/time.
    • When a utility does not submit a response to PRIS within 2 working days you can file an AVR against them.
  • Non-Participant: Company is not currently participating in Positive Response
    • The utility owner/operator is not currently participating in the PR program. Keep in mind that until January 1st, 2021, utility owner/operators are not required to submit response information to PRIS. Any time after that date an AVR can be filed against non-participants

Any time a utility has not marked, submitted a response, or contacted you within 2 working days of the notification and you are not sure what to do, contact MS811.

We hope that PRIS will improve communication as well as increase safety. If you have any questions or concerns about the PRIS, feel free to contact Amanda Russell or Joanna Henderson at (601) 368-1150.
