How You Can Help

The California Public Utilities Commission maintains the State Broadband Coverage Map which identifies coverage areas.  Currently this data is solely provided by carriers such as ATT, Verizon and Comcast.  By completing the CPUC Broadband Survey, you will be confirming or refuting carrier supplied information and helping the CPUC provide a more accurate description of coverage in California.  This confirmation process is known as ground proofing (see Glossary).

Take the CPUC Survey!

Survey The information you provide by completing the survey and downloading the smartphone app will be incorporated into the consumer feedback layer, and to validate or invalidate provider's service availability information.
