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.

Founded in 1984, the non-profit Texas811 is the largest one-call notification center in the country. We protect billions of dollars of underground utilities and the people who live and work around them.

We notify utility companies that are registered with Texas811 of the planned excavation, and they send locators to mark their underground utility lines. These markings represent the approximate location of the underground utility lines.

Texas811 is the link between your plans to dig and our member utility companies.

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

Our mission is to facilitate damage prevention, promote public safety and protect the environment through stakeholder education and communication.

Damage Prevention Educational Events

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.

Hours and Holidays

Texas811 provides around-the-clock availability via the Internet or phone 811

Texas811 observes all Texas State Holidays (which are not included in the two business day waiting period prior to digging)

If a Federal holiday falls on the weekend, it will be observed on the observance day aligned with the law.
