Liberty Mutual Fax Number — Fax Claims and Policy Documents
Liberty Mutual splits incoming documents across separate units for auto claims, subrogation, and policy service, and each unit publishes a different fax line. The number printed on your claim correspondence or in your policy packet is almost always the one tied to your specific file. Sending proof of loss or an accident report to the wrong queue is the usual reason paperwork stalls, so match the fax destination to the claim or policy reference you already have.

Tip: Write your policy number, and the claim number if a claim is open, on every single page so loose sheets can be matched back to your file.

Keep a delivery confirmation from Send FAX Mail as your record that the proof of loss or accident report actually arrived.
