Texas811 makes every attempt to ensure registering your underground facilities is as effortless as possible.

We offer a variety of methods for member mapping submissions. These formats, along with detailed instruction and requirements for updates, are included on our Member Mapping Submission Form below. Safety and damage prevention are a top priority at Texas811; therefore, we encourage our members to update their database as frequently necessary, and per Chapter 251.107 of the Texas One-Call law at least quarterly.


Members have access to view mapping data 24/7. Please sign up at the Texas811 Portal and contact the Texas811 GIS team for access.

For additional information, please contact the Texas811 GIS team by email or phone: 888-771-1877 (option 3).
