Guidelines for Broadband Data Submission         

The Broadband Data Request will be sent to California broadband providers on or before March 1st of each year, outlining any instructions or changes in our data collection process. Please submit your data in accordance with the data request instructions by the submission deadline.  

A separate Voice Data Request for California Voice provider's was sent on April 3, 2020. Please submit your data in accordance with the data request instructions by the extended submission deadline of June 1 for your voice data.    

Pursuant to Public Utilities Code §§ 311, 314, and 716, inter alia, and Decision D.16-12-025, all communications providers certificated and/or registered with the California Public Utilities Commission (CPUC), that also file Form 477 with the Federal Communications Commission, shall submit annually to the Communications Division by April 1st, broadband subscriber and deployment data at a Census Block level as of the prior calendar year’s end in a form as designated by Communications Division Staff.  Only Mobile providers may submit broadband subscriber data at the Census Tract level.  All providers may fulfill the subscriber reporting requirement by submitting subscriber data at the more granular street address level.

Starting in the 2019 data collection cycle, Fixed Wireless providers are no longer required to submit tower location information. They are required to submit broadband Deployment data at the Census Block level.
