The Source of Workers' Compensation Insurance Coverage Data

The Insurance Commissioner's regulations contained in the California Workers' Compensation Uniform Statistical Reporting Plan – 1995 (Uniform Statistical Reporting Plan) require insurers to report to the Workers' Compensation Insurance Rating Bureau of California (WCIRB) policy information that pertains to California workers' compensation insurance. The information available via this website is extracted from the data reported to the WCIRB. The Uniform Statistical Reporting Plan requires insurers to report policy information to the WCIRB no later than thirty (30) days from the inception date of the policy. The WCIRB makes the name of the insurer available on this website within thirty (30) days of receiving the policy information from the insurer.
