5.3 Locate Reference Number
The excavator receives and maintains a reference number from the 811 center that verifies that the locate was requested.
All calls from excavators processed by the 811 center receive a unique message reference number, which is contained on all locate request messages. The excavator records this number; it is proof of notification to the members. The computer-generated request identifies the date, time, and sequence number of the locate request. Each locate request ticket (notification) is assigned a unique number with that 811 center, the requestor, and the facility owner/operator. This number distinguishes this ticket from all other tickets so that it can be archived and retrieved upon request to provide the details of that request only.
