The Texas Notification System consists of three separate Notification Centers. Each Notification Center is responsible for receiving information about a planned excavation and sending that information to its member utility companies and to the other two Notification Centers. The utility companies, once notified, have 2 working days to send their personnel or contract locators to the excavation site to mark the approximate location of their underground facilities. An excavator only needs to call one of the Notification Centers. That center is responsible for relaying the information to the other centers.

If you need utility lines marked or located, you can call the statewide number 1-800-545-6005 or you may contact a Notification Center directly. You only need to contact one center. That center will relay the information to the other two centers.
