Chase does not have one general fax number. Each department publishes its own: 1-866-701-9886 for fraud claims on personal checking, savings, debit cards, and credit cards; 1-866-282-5682 for mortgage assistance documents; and 1-614-422-7575 for Home Lending fraud and for mortgage changes after a customer's death. All of these come from chase.com. For consumer credit card disputes, Chase does not publish a fax number, so follow the instructions on your dispute letter.

This guide lists the Chase fax numbers we verified, explains when your own letter overrides them, and covers what to put on each page so documents reach the right file.

  • Verified chase.com numbers for fraud, mortgage assistance, and estate mortgage requests
  • The letter about your case beats any general number
  • Card disputes: no published fax; use the online dispute tools or your letter

Notes:

  • Fraud: the Report Fraud page pairs each fax with a phone line. For personal accounts and debit cards, call 1-800-935-9935 (option 8); for personal credit cards, 1-800-955-9060 (option 2). Calling first usually gets you a claim number for your cover sheet.
  • Mortgage assistance: Chase says to send all financial documents at once, write the full loan number at the top of every page, and keep paying your mortgage while the application is reviewed. Questions go to your Relationship Manager or 1-800-848-9380.
  • Estate kits: each kit includes a cover sheet and asks for a copy of the certified death certificate. If you are not an account holder, Chase says to submit by fax or mail.

The number on your letter wins

When Chase opens a claim or case, the letter or secure message about it usually says how to send documents. That instruction is tied to the team holding your file and overrides the general numbers above.

Be careful with numbers that reach you any other way. Scammers posing as bank staff ask people to fax IDs and statements to numbers they control. If someone calls or emails you with a Chase fax number, hang up and check it against chase.com or the number on the back of your card before sending anything.

Credit card disputes

We did not find a fax number for consumer credit card disputes on chase.com. Numbers circulating on blogs and fax directories are not published by Chase, and a dispute packet usually contains your card number and transaction details.

Instead:

  • Dispute online or in the Chase app, where you can usually add documents to the claim.
  • Sign in to chase.com and send a secure message with your documents if your case allows it.
  • Follow your dispute letter. If Chase asks for documents by fax or mail, the letter tells you where.
  • Call the number on the back of your card and ask where to send supporting documents for your case.

If the charge involves fraud rather than a merchant dispute, the fraud fax above applies once you have reported it. For general guidance on bank disputes, see our guide to faxing a bank.

How to fax Chase, step by step

  1. Pick the right line from the table, or use the one on your letter.
  2. Write your identifier on every page: claim number for fraud, full loan number for mortgage assistance.
  3. Use Chase's cover sheet if the kit or letter provides one.
  4. Scan clearly. Bank statements and pay stubs have small print, so scan straight and in black and white.
  5. Send one complete package. Chase's mortgage team specifically asks for all documents together.
  6. Keep the confirmation with a copy of what you sent.

No fax machine needed: you can send a fax online for $2.99, with no subscription and no account. Chase also notes that faxing mortgage assistance documents is free from any Chase branch.

Mistakes that slow Chase down

  • Using the fraud line for a mortgage application, or the reverse. Each line feeds a different team.
  • No loan or claim number. Loose pages without one are hard to match.
  • Partial packages. Missing pay stubs or a missing signature page can stall a mortgage assistance review.
  • Full account numbers where not needed. On cover sheets, the last four digits are usually enough unless Chase asks for the full number, as the mortgage team does for loan numbers.
  • Faxing a number from a search result. Use chase.com or your letter.

Faxing Chase works when you match the document to the department, put the right reference number on every page, and keep your confirmation.
