Credit Score Models and Reports Initiative
Publication of additional historical credit data
On July 1, 2026, Fannie Mae published historical credit score data for FICO® Score 10T and additional data for VantageScore® 4.0. This effort aims to enhance transparency and provide additional insights to our industry partners.
VantageScore 4.0 and FICO Score 10T Credit Score Model Update
What’s Changing
The Fannie Mae Selling Guide will be updated to allow for the current use of VantageScore 4.0 and future use of FICO Score 10T credit scores for loans delivered to Fannie Mae. These changes are effective immediately and will be implemented through a limited lender rollout to help ensure operational readiness across our systems and the industry before making it broadly available.
What Stays the Same
Lenders not participating in the limited rollout must continue using Classic FICO scores from all three credit bureaus for Desktop Underwriter® and manually underwritten loans until receiving approval for new score usage or broad availability.
Timeline and Next Steps
- VantageScore 4.0
- Available now for a limited number of approved lenders to use through a tri-merge credit report from each credit bureau for new casefiles submitted via Desktop Underwriter® and loans delivered through Loan Delivery. Lenders interested in using VantageScore 4.0 can express interest online or contact their Fannie Mae representative.
- FICO Score 10T
- Available at a later date. We'll provide advance notice and implementation guidance before launch.

Previous Announcements & Statements
Current Credit Score Model
In accordance with the requirements of the Validation and Approval of Credit Score Models Rule (12 C.F.R. Part 1254), Fannie Mae performed the required assessments for the Classic FICO credit score model and determined that Classic FICO should be approved for continued use by Fannie Mae. The Federal Housing Finance Agency announced its approval of this determination on Nov. 10, 2020. This was an incremental step until further updates in accordance with the Rule.
