The one fax line Rocket Mortgage publishes

Rocket Mortgage lists (877) 382-3138 on its disclosures and licenses page, next to the Detroit servicing address, in the section covering written requests about a loan. That is the destination for the three letters a borrower most often has to put in writing: a qualified written request, a notice of error, and a request for information.

There is no separate published fax for payoffs, insurance documents, or hardship packages. Rocket routes most day-to-day documents through your Rocket Account instead, so a fax is the right choice when you need a dated written record rather than an upload. If Rocket has sent you a letter that names a department fax, use the number on that letter: it belongs to the team already expecting your document.

What borrowers send to this line

The paperwork that reaches this fax is written correspondence about a specific loan:

  • A qualified written request or notice of error, when a payment, escrow figure, or fee on your statement is wrong
  • A request for information, such as the identity of the loan owner or a payment history
  • A written payoff request, with the loan number and the payoff date you need
  • Insurance loss documents when a claim check has to be endorsed
  • A third-party authorization letting a spouse, attorney, or agent speak to Rocket for you

Write the loan number on every page, not only the cover sheet. A short letter runs one or two pages; a letter with statements attached usually runs five to fifteen.

What happens after the fax goes through

This line receives documents and does not answer on the same channel. Rocket replies by mail or through your Rocket Account, so there is nothing to wait for on a fax line, and there is no acknowledgment page coming back.

That makes your own proof the thing that matters. FaxTerra emails a delivery receipt showing the destination number and the time the fax was accepted by the receiving machine. Keep it with your copy of the letter, since a written request only starts a servicer response clock once it has arrived, and the receipt is what dates it.

Verify the number before you send

A servicing letter carries your name, address, and loan number, so confirm the destination before it leaves:

  • Use the fax number printed on the Rocket letter or form in front of you, when you have one.
  • Otherwise read it directly from rocketmortgage.com/legal/disclosures-licenses, which is where Rocket publishes it.
  • Do not use a number from a search snippet or a third-party mortgage directory. Servicing numbers move when a servicer reorganizes, and directories keep the old one.
  • If your loan was transferred to another servicer, the fax number transfers with it. Check the transfer notice you received rather than assuming Rocket still services the loan.

FAQ

Frequently Asked Questions

What is the Rocket Mortgage fax number?

Rocket Mortgage publishes (877) 382-3138 on its disclosures and licenses page, for written servicing correspondence including qualified written requests, notices of error, and requests for information. The mail alternative is P.O. Box 442359, Detroit, MI 48244.

Can I fax a payoff request to Rocket Mortgage?

Rocket does not publish a separate payoff fax. A written payoff request with your loan number can go to the servicing correspondence line, and Rocket can fax the payoff quote back to a number you supply. The quickest route for a routine payoff figure is your Rocket Account.

Will Rocket Mortgage fax me a reply?

Not as a rule. The published line takes documents in, and the answer comes by mail or in your Rocket Account. Keep your delivery receipt as proof of the date your request arrived.

Do I need a fax machine to fax Rocket Mortgage?

No. Upload a PDF or photos of your letter to a free FaxTerra account, enter the number, and send from a phone or computer. Nothing is installed and no fax line is involved on your side.

Is FaxTerra affiliated with Rocket Mortgage?

No. FaxTerra is an independent online fax service. We deliver your document to the fax number you enter and confirm when it arrives. We cannot look up your loan or speak to Rocket for you.
