Cal. Code Regs. tit. 10 § 2052.3
No true or fictitious name proposed by an applicant or licensed producer shall be approved if such name states or implies, or would lead reasonable persons to infer, that the applicant or licensed producer is an underwriter (i.e., an insurer or guarantor). This section, however, does not prohibit any agent from indicating that such agent is an authorized representative of an admitted insurer if such agent is also clearly designated as an agent representing such insurer or a natural person otherwise entitled to do so from using the title "Chartered Life Underwriter" (CLU) or "Chartered Property and Casualty Underwriter" (CPCU), and no approval from the Commissioner is required for the use of such association, wherein each member of the association is also separately licensed, may use the word "underwriter" in the name under which the association is licensed.
