All organizations applying for grants via Grants.gov using the SF 424 forms must complete a one time registration with Grants.gov. Principal Investigators do not need to register with Grants.gov. An Authorized Organizational Representative (AOR) or Signing Official for the institution needs to complete this step. If you are unsure of whether your institution has an account with Grants.gov, contact your Office of Sponsored Research. This process could take several weeks, so applicants are strongly encouraged to begin the registration process as early as possible.
