Guidelines for Voice Data Submission

The Voice 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, April 1.

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. Please note that census block reporting should be based on the 2020 census block boundaries (see shapefile link below).
