MassMutual Fax Number — Fax Claims and Documents

MassMutual, headquartered in Springfield, Massachusetts, administers life insurance, annuities, and disability income coverage through separate service teams, and each handles its own fax intake. A beneficiary designation change, a claim, and a policy service request typically go to different numbers, so the line printed on your form or service letter is usually the one tied to your contract. Confirm the destination before sending, particularly for beneficiary changes, which often have a dedicated intake at MassMutual.
