What do I put in the Federal Identifier field of the SF424 (R&R) cover component?
If “Type of Application” is “New”, you can leave the Federal Identifier field blank on the first submission attempt. However, the Federal Identifier field becomes a required field when submitting a Changed/Corrected application to address errors/warnings. When submitting a Changed/Corrected “New” application, enter the Grants.gov tracking number of the previous submission attempt (e.g. GRANT00123456). If you are unable to find the tracking number, enter “N/A”. If “Type of Application” is “Renewal”, “Revision” or “Resubmission”, enter the IC and serial number of the prior application/award number (e.g. CA123456). For these types of applications, do not change the Federal Identifier field when submitting Changed/Corrected applications.
