Electronic Positive Response (EPR) & WebTMS EPR Codes as defined by DigAlert

The EPR codes 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.  WebTMS users will automatically post EPRs when they post a response within WebTMS itself.

For Excavators wishing to check responses, please see → Checking Electronic Positive Responses.  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 Electronic Positive Response Best Practices

Code 016 will not be available for use until January 1st 2023
