About

Committed to protecting billions of dollars of underground utilities & the people around them by notifying utility members of someone's intent to dig.

When you need to know where underground utilities are located before you dig, contact Texas811.

It's a FREE service!

Texas811 creates a ticket that alerts the nearby registered utility companies to go to your worksite and mark where their underground utilities are located.

This helps prevent unintended consequences from digging into an underground utility such as injury, damage to property and service outages.

Texas811 is the link between your plans to dig and our member utility companies. Texas811 does not actually mark underground utilities. We notify our member utility companies of the planned excavation and they send locators to mark their lines.

Founded in 1984, the non-profit Texas811 is the largest one-call contact notification center in the country with more than 2,000 members.

Texas811 members are utility companies and municipalities who choose Texas811 to provide them notifications of planned excavations near their underground lines.

To educate excavators, emergency responders and the public, Texas811 hosts damage prevention educational events; an annual Summit and training sessions. Texas811 manages the largest Facebook page of any state one-call organization in the country, which helps educate the general public about underground safety.

DIGTESS

DigTESS is the name we were known by from our inception in 1984 until 2009. The 811 number was created in 2007, and we changed our name to Texas811 in 2009. The Dig TESS name was so well known that to this day we receive calls requesting a Dig TESS.

Our DigTESS heritage still lives in our blood. It is in every ticket we process, in our damage prevention programs and in our customer service.

When you want DigTESS quality, you’ll find it at Texas811!
