The Desktop Underwriter® (DU®) validation service uses third-party data vendors to independently validate borrower income, employment, and asset data, providing our lenders Day 1 Certainty® on validated loan components. Fannie Mae has an open platform for data vendor participation to provide choices to our customers. Lenders may participate in the DU validation service through relationships with vendors of their choice that can provide Day 1 Certainty validation reports accepted by Fannie Mae. See below for a list of vendor options and eligible reports.

To mitigate the risk that Fannie Mae assumes by offering representation and warranty relief on validated loan components, we have a structured process and guidelines for determining eligible verification reports. However, vendors and other approved vendor tools are subject to lenders’ requirements and approval processes. As additional eligible reports become available, Fannie Mae will add them below. See Prospective Report Suppliers for a list of those that have entered Fannie Mae's report supplier assessment process. Suppliers that want to participate should click here.

Prospective Report Suppliers (as of December 10, 2019)

Fannie Mae is working to expand the pool of eligible verification reports. Prospective report suppliers for the Fannie Mae DU validation service are listed in the table below. "Coming Soon" indicates that a prospective report supplier is participating in the report supplier assessment process. These entities may or may not meet the requirements of Fannie Mae's vendor assessment framework, and may or may not ultimately participate in the DU validation service. "In Pilot" indicates that a prospective report supplier completed the assessment process and necessary technology integration, and is set up in DU for lender testing on a limited basis as determined by Fannie Mae and may or may not be rolled out more broadly.

The table is updated as status changes occur, and we will notify lenders when additional report suppliers complete the pilot phase and become available in DU for all users.

Report suppliers may sell their reports directly to lenders, have authorized distributors, or both. Vendors that would like to become report distributors should contact report suppliers directly. Check with the report supplier if you have questions about their participation in the DU validation service.

NOTE: Fannie Mae does not endorse any particular vendor, and does not represent or warrant that any report supplier will meet a lender's requirements. Lenders must establish controls to manage and monitor the vendors in accordance with their own regulatory requirements.
