WCRB Web Services



The WCUnderwriting Web Service provides 24/7 access to the experience modification factor with no human interaction. Instead of an underwriter manually searching for experience modification factors using the wcrb.org Experience Modification Lookup member product, participating carrier’s set up their server to connect with the WCRB’s web service by sending unique credentials (provided upon registration for this service), a state code, Risk ID and/or policyholder’s Federal Employer Identification Number (FEIN) and the web service will return the corresponding experience modification factor. This web service is built in conformance with WCUNDERWRITING - a national standard developed by the Workers Compensation Insurance Organizations (WCIO).

See the WCUnderwriting Circular 3185 for more information.
