Verified Liberty Mutual fax numbers

Verified November 2026:

What you are sending Fax number Source

Notes:

  • Claims contact fax: it appears in the Texas section of the disclosures page (in English and Spanish), as the contact for questions about a claim. Liberty Mutual does not describe it as a general document intake line, so put your claim number and a clear note on the cover sheet, or ask your adjuster where to send documents.
  • NJ PIP: the letter gives phone 1-800-486-6152. It sends precertification requests to an outside vendor, CSG, at a separate fax listed in the letter, not to Liberty Mutual's PIP fax.

Uploading with EZDrop

Liberty Mutual's EZDrop tool at ezdrop.libertymutual.com lets you upload documents to a claim. You'll need the claim number and claim type, and files can be up to 10MB (5MB for text and image files on workers' compensation claims). File names should not include personal information. Uploads attach directly to the claim, so there is nothing to match by hand.

The number from your adjuster wins

Once a claim is open, your adjuster can give you a fax number for that claim. Use it: it routes to the team handling your file. If someone contacts you unexpectedly asking you to fax ID or bank details to a "Liberty Mutual" number, confirm it on libertymutual.com or by calling the number on your policy documents first.

How to fax Liberty Mutual, step by step

  1. Try EZDrop first if you have your claim number.
  2. Pick the right fax: your adjuster's number, the claims contact fax, or the NJ PIP provider fax.
  3. Add a cover sheet with your name, claim number and what's enclosed.
  4. Write the claim number on every page.
  5. Fax it and keep the confirmation.

You can send a fax online for $2.99 with no subscription and no account.

Mistakes that slow down a Liberty Mutual claim

  • No claim number on the pages.
  • Precertification sent to the PIP fax. In New Jersey it goes to CSG.
  • Files too large for EZDrop. Split anything over the limit.
  • Using a fax number from a directory site rather than Liberty Mutual's own pages.
