On March 26, 2004, HUD published an interim rule implementing an Office of Management and Budget (OMB) policy directive that requires grant applicants, other than individuals, to provide a Data Universal Numbering System (DUNS) number when applying for Federal grants or other assistance agreements on or after October 1, 2003. HUD is applying this policy widely to its assistance programs in order to have a single identifier for applicants and to facilitate the transition to electronic application submission. This final rule follows publication of the March 26, 2004, interim rule. HUD did not receive any public comments on the interim rule and, therefore, is adopting the interim rule without change.
