Guidelines for Broadband Data Submission         

A 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.  

NEW! 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 that also file Forms 477 with the Federal Communications Commission shall submit annually to the Communications Division, voice and broadband subscriber and deployment data at a census block level as of the prior calendar year’s end. As an alternative, providers may fulfill the subscriber requirement by submitting subscriber addresses, which the CPUC will then convert to census blocks.

If you have not already done so, please also submit Middle Mile Network data in accordance to the Guidelines for Middle Mile Facility Data Submission.
