CNA Insurance Fax Number — Fax Claims and Documents

CNA Insurance routes claims, policy changes, and beneficiary updates through different intake fax lines depending on the line of business, so there is no single number that covers everything. Property and casualty claims, life policy servicing, and appeals each go to separate teams, and using the wrong line usually means your paperwork sits unprocessed. Pull the fax number printed on your policy declarations page or claim acknowledgment letter, and confirm it by phone before you send anything time-sensitive.

What You Can Fax to CNA Insurance

  • Insurance claims
  • Policy change requests
  • Beneficiary designation changes
  • Proof of loss documentation
  • Appeals and grievances
Tip: Put your policy number and claim number at the top of every page, not just the cover sheet, since CNA's claims team often separates pages during scanning. For a property or casualty claim, attach the date of loss, a plain description of the damage, and a daytime phone number where an adjuster can reach you. Send FAX Mail returns a delivery confirmation you can keep as proof the proof-of-loss documents went through on time.
