Why AmTrust Financial has no single fax number
Like most carriers, AmTrust Financial splits incoming faxes across separate teams. What you send to claims will not arrive at appeals unless the number matches. Identify the destination team first, and the paperwork lands with the right desk.

Faxing to AmTrust Financial — FAQ
The answer varies by document and department at AmTrust Financial. Some adjusters accept fax for a signed form but ask that supporting documents be uploaded. When fax is the right channel, an online fax gets it there without a machine. The channel that works is whichever one the receiving department actually asks for.
No. AmTrust Financial routes faxes to separate department lines, so the claims department and the treatment authorization team do not share a number. Claims, the medical bill review unit, and appeals each keep their own line. Verify the current fax for the treatment authorization team or your target team first. Which line is right depends on the department, not the workers' compensation insurer as a whole.
Put your claim number on every page, plus the claim or reference number when there is one. Add a cover sheet addressed to policyholder services at AmTrust Financial with a callback number. A delivery confirmation then tells you the fax reached AmTrust Financial. The identifiers matter as much as the document itself.
Faxes reach AmTrust Financial whenever you send, but when they are handled varies by department. Departments keep a Monday-to-Friday schedule. An urgent request carries a shorter timeframe, so send well ahead. Confirm receipt of an appeal or authorization rather than assuming it was actioned.
