Response Codes
Electronic Positive Response (EPR) Codes as defined by DigAlert
The EPR codes on this page are maintained by DigAlert in conjunction with USA North 811 for continuity within the state of California. These codes are used for members to submit responses to DigAlert's EPR servers.
These codes are changing January 1st, 2025. Please make the needed adjustments on your systems.
The codes with red font and strike through will be REMOVED
The codes highlighted in green are being reworded
The code highlighted in blue will become system use only and not selectable by the operator
For Excavators wishing to check responses, please see → Verifying Responses via Website. The responses will be displayed with the description, not the code.
More information!
For more information on what the response codes mean and when to use them, please see Best Practices.

To integrate these response codes with your ticket management system, you can retrieve this list via API by accessing https://das.digalert.org/v1/getresponse-codes as a GET. This API will return the following JSON formatted message.
Field definitions:
“last_change” displays the date the last change was made to the EPR codes as a string
“version” displays the EPR Codes JSON file version as a string
“response_codes”:
“response” displays the EPR response code (three numbers as a string)
“state” displays the state/center as a string (max 4 chars) - For Underground Service Alert of Southern California will always show CA-S
“description” displays the readable description of the EPR response code as a string
“allowed” displays wether the EPR code is available for public use as a bit/boolean. “false” means this code can only be used by DigAlert’s system internally. “true” means the EPR code can be used by members when posting.
This will not show the new list until it goes live on January 1st, 2025
