The Insurance Unit maintains a record of the workers' compensation insurer for every employer in the state. This record, known as the insurance register, dates back to the 1930's and facilitates the filing and investigation of claims. The injured worker may contact this office directly to obtain the insurance information of an employer.

Through legislative action, the Workers' Compensation Rating and Inspection Bureau (WCRIBM) became the official repository of insurance policy coverage in 1991. The DIA was provided with computer access to this database, which includes policy information from 1986 to present. Information from 1987 and prior must be researched through the files at the DIA, now stored on microfilm.
