Before you can register as an organization applicant with Grants.gov, you will need to create a username and password on Grants.gov and complete registration in SAM.
Complete an Authorized Organization Representative profile and create a username and password on Grants.gov. Note: an applicant entity's "Unique Entity Identifier (UEI)" must be used to complete this step. On April 4, 2022, the UEI used across the federal government changed from the Data Universal Numbering System (DUNS) Number to the Unique Entity ID (generated by SAM.gov). UEIs are used to identify entities registered in SAM. For more details on UEIs, read What is a UEI? on the JustGrants Resources website.
The process of registering in Grants.gov can take up to 4 weeks. Once the SAM registration/renewal is complete, the information transfer from SAM to Grants.gov can take as long as 48 hours. OJP recommends that the applicant register or renew registration with SAM as early as possible. See the Register page on Grants.gov for details and instructions.
