California High Cost Fund-B

The California High Cost Fund-B (CHCF-B) was implemented in accordance with Public Utilities Code § 739.3.  It provides subsidies to carriers of last resort (COLRs) for providing basic local telephone service to residential customers in high-cost areas that are currently served by Pacific Bell Telephone Company dba AT&T California, Verizon California Inc., Citizens Telecommunications Company of California dba Frontier Communications of California, and Cox Communications.  The purpose of the subsidies is to keep basic telephone service affordable and to meet the Commission’s universal service goal. 

The downloadable file below contains a list of high cost 2010 Census Block Groups (CBGs) and the associated cost of service per landline within each CBG where the cost is $36 or more per line, according to the Cost Proxy Update Provision adopted by Commission Decision (D.)14-06-008 in Rulemaking (R.) 09-06-019. The Census Block Groups are in the “Excel Workbook" file format. Download. Please click here for the September 30, 2014 Administrative Letter from Communications Division to CHCF-B Carriers regarding the implementation of 2010 Census Block Groups (CBGs) for the filing CHCF-B Monthly Claims Pursuant to Decision (D.)14-06-008.


CHCF-B is funded by an all-end-user surcharge billed and collected by telecommunications carriers which, in turn, remit the surcharge monies to a financial institution as directed by the Commission or its representatives.  Procedures for the administration of CHCF-B and guidelines for qualification of COLR are set forth in the Adopted Universal Service Rules adopted by the Commission in D.96-10-066.  

There is an advisory board, the CHCF-B Administrative Committee
