What Is a Mortgage Servicer?

Short answer

A mortgage servicer is the company that collects your monthly payment, sends your statements and manages your escrow account; it may not be the lender that made the loan. When servicing is sold, federal rules require notice at least 15 days before the transfer from the old servicer and within 15 days after from the new one, and for 60 days an on-time payment sent to the old servicer cannot be treated as late (as of November 2026).

Definition

The company that handles your loan day to day: it processes payments, answers questions, tracks principal and interest, manages escrow, and works with you if you fall behind. Your lender is the institution that originally loaned the money.

Worked example

Example only: you close in March and make your April 1 payment to Servicer A. A letter from Servicer A dated May 10 says servicing moves to Servicer B on June 1, and gives the last day A accepts payments and the first day B does. On June 1 you mail your payment to Servicer A by mistake and it arrives before the due date. Because this falls inside the 60 days after the transfer, Regulation X says it may not be treated as late for any purpose; A must send it on or return it, and you start paying B. Your loan terms and escrow balance move with the loan unchanged.

Servicing transfer rules (12 CFR 1024.33)

Under the CFPB's Regulation X, as of November 2026, the transfer notice must include:

• The effective date of the transfer
• Name, address and a toll-free or collect number for both the old and new servicer
• The last day the old servicer accepts payments and the first day the new one does
• Whether optional insurance, such as mortgage life coverage, is affected
• A statement that the transfer does not change your loan terms other than servicing

Your escrow account moves with the loan, so keep paying the same total PITI to the new servicer.

How to find your servicer

The CFPB says to check your monthly statement or coupon book first. If you can't, use the free MERS ServicerID lookup at mers-servicerid.org or call (888) 679-6377. You can search by property address, by borrower name and Social Security number, or by the MIN on your mortgage. Beware of letters that ask you to send payments elsewhere without a matching notice from your current servicer.

In South Florida

In South Florida, escrow often covers large property tax and windstorm and flood insurance bills, so a servicing transfer is a moment to check that your policies list the new servicer as mortgagee and that tax and insurance payments are not missed. Many loans closed through a broker like QMS are serviced by a company other than the lender on your closing disclosure.
