Reminder: Use of UEI Instead of DUNS on Federal Applications

Beginning on March 19, 2022, SAMS Domestic will implement the newest version of the SF-424 forms on all applications. The SF-424 will be updated from V3.0 to V4.0, which will require applicants to enter their UEI instead of the DUNS. 

When submitting federal applications after this date, make sure to check agency form requirements as appropriate.
