Do I need to provide the Funding Opportunity Number (Item #12) & the Competition Identification Number (Item #13) on the SF-424?

If you submit your application electronically via Grants.gov, then you need to provide these numbers. They are located on the Grants.gov Web site on the application download page and also on the application package page once it is downloaded. If you submit your application in paper format by mail or hand delivery, then you do not need to provide these numbers as they are used strictly for the electronic package submitted via Grants.gov.
