Workers' compensation information system (WCIS)

Workers' compensation claims by region, county, and postal code

First Reports of Injury (FROIs) submitted by Trading Partners to the Workers’ Compensation Information System (WCIS) capture three pieces of location information about California’s workers’ compensation claims. The three pieces are the postal code of the accident/injury site; the employer’s complete address; and, the employee’s address.

The tables, charts and reports below are taken from the postal codes of each of these three pieces. The numbers reflect the WCIS database information as of the run date of the report.
