Fax Washington Workers' Compensation — Cover Sheet and Documents
The difference between a matched filing and a stalled one at Washington State Department of Labor and Industries is usually the cover sheet — here is what to include.

This page covers what to label, what to fax, and how to find the office's current fax number.
Does Washington State Department of Labor and Industries accept a fax?
Workers' compensation is one program where fax is genuinely common — claim forms, a first report of injury, medical reports, wage statements, and appeal filings often go by fax to the board. Some documents may require e-filing, so confirm the current line and format. Treat fax as one channel alongside online and in-person, not the default for every document.
