Sun Life U.S. Fax Number — Reach the Right Department
Faxing Sun Life U.S. starts with a fact that trips people up: the disability insurer routes documents to separate department lines, not a single number. Headquartered in Wellesley, Massachusetts, Sun Life U.S. is a disability and absence carrier that handles claims and documents by fax and online. Claims are not the same line as the appeals team, so identifying the destination is what gets the paperwork where it belongs.
