The Department of Labor does not have one fax number; each program runs its own. The Energy Employees Occupational Illness Compensation program (DEEOIC) fax is 206-224-1216. The Black Lung program (DCMWC) national office fax is 202-693-1395. For federal workers' compensation (FECA), DOL's fax line 800-215-4901 is for medical authorization requests. FECA claim forms go through the ECOMP portal instead. Put your case number at the top of every page.

This guide lists the DOL fax numbers we verified on dol.gov, explains which documents each line accepts, and covers the things you cannot fax at all.

  • Verified numbers for the Energy, Black Lung, and FECA programs, including district offices and resource centers
  • What to send online or by mail instead, especially FECA claim forms and bills
  • The case number rule that keeps faxes attached to your claim

The number on your letter wins

If a claims examiner, district office, or resource center sent you a letter that names a fax number, use that number. It routes to the team already holding your file, which beats any general line on this page.

Letters also tell you which case number to use. That number is the key DOL uses to match incoming pages to a claim, and it belongs on every page you send.

Federal workers' compensation (FECA)

FECA is the program most people mean when they search for an OWCP fax number, and it is also the one where fax plays the smallest role.

  • Claim forms are filed through ECOMP, the Employees' Compensation Operations and Management Portal. DOL's own training material says all FECA claim forms are to be filed there.
  • Correspondence and evidence can be uploaded into your case through ECOMP or mailed to P.O. Box 8311, London, KY 40742-8311.
  • Bills and the OWCP-915 and OWCP-957 reimbursement forms must be mailed to P.O. Box 8300, London, KY 40742-8300, according to DOL's FECA contacts page.
  • Medical authorization requests are where fax still applies. DOL tells providers to fax the right Medical Authorization form and supporting records to 800-215-4901, or to use the OWCP Web Bill Processing Portal. Authorization cannot be requested until a claim number exists.

So if you are an injured federal worker, the 800 fax line is usually your doctor's job, not yours. Your own paperwork goes through ECOMP or the mail.

How to fax DOL, step by step

  1. Pick the right program. FECA, Energy, and Black Lung claims are handled by different divisions, and a fax to the wrong one does not get forwarded quickly.
  2. Check your letter for a specific fax number.
  3. Write your case number at the top of every page. DOL asks for this on all correspondence. Use clean 8.5 x 11 paper.
  4. Add a cover page with your name, case number, phone number, what you are sending, and the page count.
  5. Scan clearly in black and white. Medical records with small print and handwritten notes lose detail at fax resolution, so scan them straight.
  6. Fax and keep the confirmation with a copy of what you sent.

Common mistakes

  • Faxing FECA claim forms. They belong in ECOMP. A faxed claim form may never become a claim.
  • Faxing bills that must be mailed. DOL states that OWCP-915 and OWCP-957 forms must be mailed in for processing.
  • No case number. Without it, pages can sit unmatched. For the Energy program, the DEEOIC case ID is what the Energy Document Portal asks for too.
  • Using a number from an old manual. DOL has retired and moved fax lines over the years. Take numbers only from current dol.gov pages or your letter.
  • Sending a wage complaint by fax. The Wage and Hour Division takes complaints by phone at 1-866-487-9243 or online.
